    A jury in the Eastern District of Oklahoma convicted Henri Piette of
    kidnapping and traveling with intent to engage in sexual relations with a juvenile.
    The district court sentenced Piette to life imprisonment on the former conviction and
    360 months’ imprisonment on the latter. He seeks to have his convictions overturned
    or his sentence reversed. We hold that the district court did not err by admitting
    evidence of Piette’s uncharged acts of molestation, and that statutes extending the
    unexpired charging period for the traveling-with-intent charge did not have an
    impermissible retroactive effect. However, we conclude that the district court plainly
    erred by misallocating the burden of proof once Piette disputed the timing of the
    kidnapping by arguing that the victim, Rosalynn McGinnis, consented. If she had
    consented, the kidnapping would have been over, and the statute of limitations would
    have begun to run, potentially rendering the indictment untimely. We reverse
    Piette’s kidnapping conviction because there is a difference between what happened
    here—Piette failing to prove by a preponderance of the evidence that McGinnis ever
    consented—and what the Constitution requires: the government proving beyond a
    reasonable doubt that she never consented at a time that would cause a statute of
    limitations problem. Finally, we reject Piette’s argument that he was denied his Sixth
    Amendment right to self-representation at sentencing. Exercising jurisdiction under
    
    28 U.S.C. § 1291
    , we affirm in part, reverse in part, and remand for further
    proceedings.

    I.
    a.
    The following account is based on trial testimony. Rosalynn McGinnis was
    born in 1984. In the early 1990s, McGinnis lived in Springfield, Missouri, with her
    parents, Gayla and Michael, and several siblings. One day, while playing at the park,
    the McGinnis children met Henri Piette’s children. The kids became close, bonding
    over sleepovers, movies, meals, and time spent on Piette’s trampoline.
    Piette first molested McGinnis at one of these sleepovers. She was nine. At
    first, she thought it was a “bad dream,” but soon she realized that it was far too
    detailed to have been a dream. R. Vol. II at 188. Gayla had not believed McGinnis
    when she was previously molested by her half-brother, so McGinnis did not tell
    anyone about what Piette did.
    McGinnis was not Piette’s only victim in Springfield. One of Piette’s sons,
    Tobias Piette, testified that he saw Piette molest several other children while they
    lived there. One day, he walked in on Piette giving an eight-year-old girl a shower
    and touching her vagina. Another time, he saw Piette giving a different young girl a
    driving lesson; he groped her butt while she sat on his lap.
    As the McGinnis and Piette children got to know each other better, so did
    Gayla McGinnis and Henri Piette. They discussed Gayla’s interest in religion and
    the Church of Jesus Christ of Latter-day Saints. Piette gradually drove Gayla away
    from her husband Michael, who did not share her interest in these topics and was
    often away from home. Soon, Michael left Gayla and the children entirely. “Almost
    3
    Appellate Case: 20-7008     Document: 010110726427       Date Filed: 08/18/2022       Page: 4
    immediately,” McGinnis’s brother testified, it was as if Piette “had stepped into
    [Michael’s] shoes.” 
    Id. at 489
    .
    But Piette ran a very different kind of home. He read Bible passages to the
    children constantly. He encouraged Gayla to physically discipline the children. He
    started separating the children and imposed something “almost like a hierarchy
    system.” 
    Id.
     He beat Gayla “countless” times. 
    Id. at 634
    . He also beat the children.
    After one of Piette’s beatings drew the attention of authorities, Piette convinced
    Gayla that she would be blamed for it, and they took the family on the road. They
    moved on an almost daily basis, passing through Arizona, Oregon, Utah, California,
    Montana, Missouri, Texas, Oklahoma, and Guatemala. Piette forced the others to
    beg for money. They lived in a tent. Piette gave McGinnis beer and molested her
    daily.
    Piette, Gayla, and the children settled in Wagoner, Oklahoma. There, Piette
    escalated his physical, sexual, and psychological abuse. He hit the children with two-
    by-fours when they said “hanged” instead of “hung.” 
    Id. at 212
    . He punched Gayla
    in the face. He raped McGinnis. She was eleven. Finally, Gayla escaped to her
    mother’s home in Independence, Missouri, and took her children with her. A few
    weeks later, Piette went to Independence and took them back.
    When they returned to Wagoner, Piette addressed his “sin” with McGinnis by
    marrying her in a secret ceremony officiated by Piette’s son Tobias. 
    Id. at 219
    .
    Piette also married Gayla around this time. The sexual abuse of McGinnis continued
    unabated. Piette performed oral sex on McGinnis and penetrated her vagina daily
    4
    Appellate Case: 20-7008    Document: 010110726427       Date Filed: 08/18/2022     Page: 5
    with his penis and fingers. She was twelve. After a run-in with Child Protective
    Services, McGinnis and her family landed in a domestic violence shelter in Poteau,
    Oklahoma, away from Piette. McGinnis briefly attended middle school in Poteau.
    On January 31, 1997, McGinnis went to school in Poteau and did not come
    home. Piette visited her on the playground that day. He told McGinnis that he loved
    her and that he would reunite their family. He told her to look for “signs.” 
    Id. at 234
    . Later that day, McGinnis noticed a sombrero and a poncho inside a school
    building; she recognized them from a trip to Mexico with Piette. She ran outside the
    school and saw Tobias Piette in a truck; he took her to Tulsa, where they met up with
    Piette and Piette’s other children. When McGinnis asked about the rest of her family,
    Piette told her there was not enough time to get her brothers and that Gayla “wasn’t
    coming back.” 
    Id. at 240
    . He introduced McGinnis to his children as “their new
    mother.” 
    Id.
     McGinnis was horrified.
    McGinnis did not attend school after the sixth grade. Piette moved McGinnis
    and his children around the country several times, taking advantage of benefits
    provided by the Church of Jesus Christ of Latter-day Saints, and avoiding detection
    by using false names and changing McGinnis’s appearance.1 Everyone was drilled
    on what to say if people started asking questions. Piette forced McGinnis to write
    letters to relatives, the media, and law enforcement, saying that she ran away from
    1
    Eventually, McGinnis legally changed her name to Stephanie Reed, one of
    the aliases Piette forced her to adopt.
    5
    Appellate Case: 20-7008    Document: 010110726427         Date Filed: 08/18/2022      Page: 6
    her “crazy” mother and “no good” family. 
    Id. at 263
    . If she misspelled a word she
    was hit. In reality, Gayla diligently searched for McGinnis.
    Piette continued subjecting McGinnis to constant physical and sexual violence.
    He raped her “[t]hree times a day, maybe more.” 
    Id. at 249
    . Shortly before
    McGinnis turned thirteen, while living in Oklahoma City, she became pregnant for
    the first time. She had a miscarriage and Piette told her to flush it down the toilet.
    Piette started giving McGinnis crack cocaine and beat her more frequently. Then,
    while living in Idaho, McGinnis became pregnant again. This time, she was fourteen.
    Piette moved the family to Mexico to avoid questions about her pregnancy, but when
    Piette brought McGinnis to the hospital the doctors said it was too soon to deliver the
    baby. Piette disagreed. He used a pocketknife to deliver the baby on the floor of a
    van. At the time, they were “living in an abandoned trailer that was on a piece of
    land that had no electricity, no water, had holes in the floors and was infested with
    bed bugs.” 
    Id. at 276
    .
    Over the next sixteen years, Piette moved the family around Mexico and
    Guatemala, rarely spending more than a few months in any one location, though they
    would take occasional trips back to the United States. McGinnis delivered eight
    more of Piette’s children. These children did not go to school, socialize, or even
    learn how to read. They were isolated from others. Piette tried to prevent them from
    learning where they were living. The children were also neglected. One of the boys
    had a single pair of shorts that he kept on his body with a rope. One of the girls
    almost drowned in a bucket of water. Piette hung her upside down to shake the water
    6
    Appellate Case: 20-7008    Document: 010110726427         Date Filed: 08/18/2022    Page: 7
    out and she recovered. The family’s lifestyle consisted of “begging on the streets and
    living from place to place.” 
    Id. at 340
    . Sometimes, McGinnis sold ice cream and
    other foods. Other times, Piette would make racist comments to provoke the locals
    into fighting McGinnis for money. Whatever the source, all money went to Piette.
    He spent it on drugs and alcohol, which he also abused.
    Years passed, and Piette’s brutality continued. McGinnis testified that there
    was never a time that Piette was not beating her. He would sometimes tie McGinnis
    to a bed or chain her to a pole for days. She testified that she has scars all over her
    face, has had both her arms broken, has been stabbed and shot, suffers chronic pain,
    and needed throat surgery to be able to speak. Piette would also terrorize their
    children, hitting them with two-by-fours, bats, rocks, pans, pickaxes, glass bottles,
    fruit, and “[a]nything that was in reach.” 
    Id. at 119
    . He would beat the children to
    the point of unconsciousness and then tell them that he loved them. “[I]t just
    surprised me how close I can get to dying without dying,” McGinnis’s firstborn
    testified. 
    Id. at 127
    .
    Piette also started molesting the children McGinnis delivered. Ma.P., Piette’s
    first daughter with McGinnis, testified at trial that when she was around five years
    old, Piette asked her to stand against the wall, pull down her underwear, and show
    him her vagina. Although McGinnis did not know exactly what was happening with
    her daughter, she was suspicious. Piette complimented and touched Ma.P.’s vagina
    more frequently as she got older. He made Ma.P. dance naked and gave her alcohol
    and drugs while he molested her. He put his mouth on her chest and her vagina. He
    7
    Appellate Case: 20-7008     Document: 010110726427         Date Filed: 08/18/2022     Page: 8
    made her touch and put her mouth on his penis, and he ejaculated in her mouth.
    When she was seven or eight years old, Piette started putting objects in Ma.P.’s
    vagina, such as frozen hot dogs and drumsticks. He would punish her by cutting up
    chilis and rubbing chili juice on his fingers, then placing them in her vagina. Piette
    also started putting his penis in her vagina. When she resisted, Piette told her he
    would either molest her or one of her sisters. One time, Ma.P. saw Piette molesting
    her younger sister, A.P., who was crying; Ma.P. was forced to put her mouth on
    Piette’s penis so he would leave A.P. alone.
    A.P. also testified about Piette’s sexual abuse. According to A.P., Piette
    started touching her vagina when she was around seven years old and continued to
    molest her every few days. She often woke up to Piette touching her vagina. Piette
    forced A.P. to masturbate his penis and ejaculated in her mouth. One time, A.P. and
    her younger brother saw Piette performing oral sex on Ma.P. A.P. and Ma.P. never
    talked about their shared experience of sexual trauma and abuse.
    Sometimes, McGinnis would travel back into the United States by herself to
    beg for money. Other times, Piette was incarcerated, and McGinnis helped him get
    out of jail. McGinnis also purchased several guns and carried a gun at times,
    although she testified it belonged to Piette. But Piette told McGinnis that he would
    kill the children, and then her, if she ever left him. He also told her that, if she got
    the police involved, nobody would ever believe her. That he would kill her. That her
    family did not want her back. That “he was the only one that would ever care for”
    her. 
    Id. at 298
    . And that she “was to do exactly what he told [her] to do or else.” 
    Id.
    8
    Appellate Case: 20-7008    Document: 010110726427        Date Filed: 08/18/2022       Page: 9
    On direct examination, McGinnis defined “or else” as Piette killing her and her
    children. 
    Id.
     McGinnis further testified that she did not take advantage of any
    potential opportunity to harm Piette because she “knew that if [she] didn’t kill him
    with the first shot or knife stab, if there was any way that he would survive, he would
    kill [her] and every one of [her] children.” 
    Id.
     at 435–36. Even had she managed to
    kill him, she testified that she believed she would be imprisoned for life and her
    children all sold into slavery. On the other hand, Piette introduced testimony from
    his father that he and McGinnis appeared to have a “very happy family.” 
    Id. at 985
    .
    Notwithstanding the fear that Piette’s threats instilled in her, McGinnis made
    several attempts to escape. Once, alone with her children in an Arizona motel room,
    she called a women’s crisis shelter, but Piette returned before the shelter could assist
    her. Another time, McGinnis took her children to Piette’s son Mikey’s house. Piette
    quickly arrived, dragged McGinnis out by her hair, and beat her. One of Piette’s
    children with McGinnis managed to escape and, although a knife fight ensued, Piette
    did not kill him.
    In 2016, McGinnis saved up $150 over the course of several months—hiding it
    by a hill to avoid Piette’s detection—and waited until Piette, who had been in and out
    of rehab, was passed out drunk. Then she took her children, found a taxi, and hid in a
    nearby town. McGinnis and eight of her children—one of her sons had already
    escaped—made their way to an American Consulate. They returned to the United
    States and settled in Kansas City, Missouri.
    9
    Appellate Case: 20-7008     Document: 010110726427         Date Filed: 08/18/2022     Page: 10
    b.
    In 2017, Piette was indicted in the Eastern District of Oklahoma and charged
    with kidnapping under 
    18 U.S.C. §§ 1201
    (a)(1) and 1201(g), and traveling with
    intent to engage in sexual relations with a juvenile under 
    18 U.S.C. § 2423
    (b). A jury
    found Piette guilty of both counts. Four legal issues relevant to this appeal emerged
    in the proceedings before the district court.
    First, the government sought to admit evidence that Piette molested his
    daughters with McGinnis as well as an unrelated girl in Springfield some years
    before meeting McGinnis (“the molestation evidence”). The government argued that
    the molestation evidence could be admitted as res gestae—meaning inextricably
    intertwined with the charged conduct—and, alternatively, under either Federal Rule
    of Evidence 404(b), covering other acts evidence, or Rule 414, covering child
    molestation evidence. Piette opposed. At a pretrial conference, the district court
    ruled that the molestation evidence came in (1) as res gestae “because it goes to the
    issue of consent, and it is inextricably intertwined with the charged crimes”;
    (2) under Rule 404(b) because it went “to the issues of both motive and plan”; and
    (3) under Rule 414 as permissible propensity evidence. 
    Id.
     at 41–42. The district
    court then turned to whether the evidence was more prejudicial than probative, saying
    only: “I still have to do a balancing test under [Federal Rule of Evidence] 403. And I
    believe that the probative value of the evidence is certainly not substantially
    outweighed by the prejudicial effect.” 
    Id. at 42
    . The district court memorialized
    these evidentiary rulings in a brief order. In that order, the court reiterated that the
    10
    Appellate Case: 20-7008    Document: 010110726427            Date Filed: 08/18/2022    Page: 11
    molestation evidence could come in under Rule 404(b) “at least [to] show motive and
    plan.” R. Vol. I at 321 (parentheses omitted).2 The order did not elaborate upon the
    court’s Rule 403 analysis. Halfway through trial, facing repeated objections, the
    district court restated its conclusory Rule 403 finding.
    Second, Piette argued in pretrial briefing that the traveling-with-intent charge
    was untimely because any enactments purporting to extend the statute of limitations
    had an impermissible retroactive effect. The district court ruled that because the
    original statute of limitations had not already expired when Congress acted, the
    legislature validly extended a live charging period, rendering Piette’s 2017
    indictment timely. The district court thus endorsed “the theory that such amendments
    may be applied retroactively to extend a filing period for charges that were still
    viable at the time of the amendment.” 
    Id. at 151
    ; cf. Hughes Aircraft Co. v. United
    States ex rel. Schumer, 
    520 U.S. 939
    , 950 (1997) (“[E]xtending a statute of
    limitations after the pre-existing period of limitations has expired impermissibly
    revives a moribund cause of action.”). Piette renewed his retroactivity argument in
    an oral motion for acquittal at the conclusion of the government’s case-in-chief,
    which the district court denied.
    2
    At trial, the court gave a limiting instruction several times when it felt that
    Rule 404(b) evidence was being presented. Usually, the court told the jurors that
    they should consider the evidence not just for motive and plan, but also for intent and
    knowledge. Subsequently, preparation replaced knowledge. Later, all five purposes
    were in play. By the end of the trial, the court was communicating the limiting
    instruction only by alluding to its existence, leaving it unclear which Rule 404(b)
    purposes were being invoked.
    11
    Appellate Case: 20-7008     Document: 010110726427         Date Filed: 08/18/2022         Page: 12
    Third, the district court noted before trial that the government would likely try
    to prove that McGinnis’s “kidnapping continued uninterrupted” from 1997 through
    her 2016 escape. R. Vol. I at 147. That was because any “break” within that twenty-
    year span would start the kidnapping count’s five-year statute of limitations. 
    Id.
     If
    the statute of limitations expired before Piette’s 2017 indictment, the charge would
    not be timely. As a result, the court anticipated sending a special interrogatory to the
    jury. At trial, the court did just that, denying a motion for acquittal on this basis and
    providing the jury the following instructions.
    DURATION OF KIDNAPPING
    The government contends that the kidnapping alleged in Count 1
    extended from January 1997 until July 28, 2016.
    Under the law, if the victim of a kidnapping is no longer held against
    her will, the kidnapping is over.
    As one of the defenses, [Piette] contends Rosalyn McGinnis was (if
    at all), at a date earlier than July 28, 2016, no longer held against her will.
    [Piette] must prove this contention by a preponderance of the
    evidence, which is defined as “more likely than not.”
    On the verdict form, only if you have found the defendant guilty as to
    Count 1, you will be asked to determine if Rosalyn McGinnis was no longer
    held against her will at an earlier date, and what that date was. This will aid
    the court in making a separate legal determination in regard to this case.
    In determining if Rosalyn McGuinness [sic] was continually held
    against her will (physically and/or psychologically), you should consider
    all the testimony you have heard in the case.
    Id. at 372. The verdict form reflected these instructions. It told the jury that, should
    it find Piette guilty of kidnapping, it must answer an additional yes/no question: “Do
    you find, by a preponderance of the evidence, that Rosalyn McGuinness [sic] was no
    longer held against her will on a date earlier than July 28, 2016?” Id. at 388. If the
    answer was yes, jurors were asked to specify the date and/or the year. The jury
    12
    Appellate Case: 20-7008     Document: 010110726427        Date Filed: 08/18/2022       Page: 13
    ultimately found Piette guilty of kidnapping and did not find, pursuant to the district
    court’s instructions, that Piette demonstrated by a preponderance of the evidence that
    McGinnis was no longer held against her will prior to July 28, 2016. Piette did not
    argue below that these jury instructions created a statute of limitations problem.
    Finally, Piette claims that he sought to represent himself in a letter to the
    district court in November 2019, and then again at the start of sentencing in February
    2020. In his letter, Piette asked the court to “terminate the services” of attorney
    Warren Gotcher and investigator Eric Cullen because of “Absolute ‘In[e]ffective
    Assist[a]nce of Counsel.’” Id. at 399 (emphasis omitted). On February 20, 2020,
    before proceeding to sentencing, the district court addressed Piette’s pending motion
    to withdraw his trial counsel. Gotcher stated that he had no objection to Piette’s
    motion. Gotcher next double-checked with Piette that Piette still wanted Gotcher to
    withdraw. Piette said “Yes.” R. Vol. II at 1107. Gotcher indicated that he had an
    “obligation to stay through sentencing” and assist Piette in filing a notice of appeal;
    he asked the district court to delay granting the motion until those tasks were
    complete. Id. Agreeing, the district court granted the motion “to be in effect
    subsequent to this sentencing hearing.” Id. at 1108. This exchange followed:
    The Court: I think it is important that trial counsel, who has been with the
    case since—well, not day one because this is Mr. Piette’s second
    appointed attorney, . . . be here through the sentencing hearing itself. So
    the Court directs that another attorney will be appointed by the Federal
    Public Defender’s office to see Mr. Piette’s case through appeal and
    that—and that is, unless, Mr. Piette wants to hire an attorney on his own.
    The Defendant: Are you saying—
    13
    Appellate Case: 20-7008     Document: 010110726427        Date Filed: 08/18/2022    Page: 14
    The Court: No, no, you tell Mr. Gotcher.
    (OFF THE RECORD DISCUSSION BETWEEN MR. GOTCHER AND
    THE DEFENDANT)
    Mr. Gotcher: We are ready to go on, Your Honor.
    The Court: All right. Is that acceptable, Mr. Piette?
    The Defendant: Yes, sir, yes.
    Id. at 1108–09.
    The district court entered hundreds of pages of Piette’s handwritten letters as
    an exhibit, noting that they contextualized Piette’s request to withdraw Gotcher. As
    the court put it: “At some points in time Mr. Piette expressed vast disagreement with
    counsel and at other times Mr. Piette thought Mr. Gotcher was the best thing since
    sliced bread.” Id. at 1109. The district court decided to “err on the side of giving
    Mr. Piette new counsel for appeal purposes.” Id. Sentencing ensued.
    The district court ruled on Gotcher’s objections to the Presentence Report and
    Gotcher argued in support of his written motion for a downward variance, which the
    court denied. After hearing from the government, the court invited Piette to speak.
    He did so for “nearly thirty transcript pages.” Aple. Br. at 46; see also R. Vol. II at
    1119–46. He maintained his innocence, touted a work ethic so strong that employers
    have called him a “human backhoe,” explained that badgers are “meaner than hell,”
    and bragged about how popular his family’s dairy products were in Mexico. R. Vol.
    II at 1141, 1144. The court sentenced Piette to life imprisonment on the kidnapping

    conviction and 360 months’ imprisonment on the traveling-with-intent conviction.
    Piette appealed.
    II.
    We begin with whether the molestation evidence was properly admitted under
    any of the three theories accepted by the district court: res gestae, Rule 404(b), and
    Rule 414. The term “molestation evidence,” as used in Piette’s appeal, encompasses
    testimony that Piette sexually abused two of the daughters he had with McGinnis and
    an unrelated girl in Springfield before he met McGinnis. See Aplt. Br. at 14. Piette’s
    daughters, known as Ma.P. and A.P. at trial, testified at length about their own abuse,
    while Piette’s son Tobias testified briefly about the Springfield girl. On appeal,
    Piette argues that both his convictions should be reversed because the district court
    improperly admitted this highly prejudicial evidence. We disagree. The intrinsic
    molestation evidence about Piette’s daughters was admissible as res gestae, while the
    extrinsic molestation evidence concerning the Springfield girl, even if admitted in
    error, likely had no effect on the verdict. We do not reach Rule 404(b) or Rule 414.
    Although the district court’s conclusory, one-sentence Rule 403 prejudice inquiry
    was deficient, our review of the case suggests that it was not an abuse of discretion to
    admit the molestation evidence under Rule 403. See United States v. Lazcano-
    Villalobos, 
    175 F.3d 838
    , 846 (10th Cir. 1999) (“We have consistently upheld
    implicit Rule 403 determinations when the determinations are supported by the
    record.”). Piette’s convictions withstand his evidentiary arguments.
    15
    Appellate Case: 20-7008    Document: 010110726427         Date Filed: 08/18/2022     Page: 16
    a.
    Piette appeals the molestation evidence’s admission on all three grounds relied
    upon by the district court, contending that his “trial was infected by repulsive other-
    act molestation evidence that created an unacceptable risk that the jury would convict
    based on emotion instead of dispassionate decision-making.” Aplt. Br. at 25. Piette
    stresses that he mounted a “targeted” and “technical but effective” defense to each
    charge at trial, only disputing the consent element of the kidnapping charge and the
    intent element of the traveling-with-intent charge. Reply Br. at 14. Because this
    significantly reduced the number of disputed facts at trial, Piette suggests the
    molestation evidence “added no probative value to the government’s case,” Aplt. Br.
    at 4, and merely inflamed the jury.
    On res gestae, Piette argues that the molestation evidence was irrelevant to
    proving his intent or McGinnis’s lack of consent, thus falling short of the
    “inextricably intertwined” standard. Id. at 31. The government responds that the
    evidence was “part and parcel of his scheme to maintain control of his family and
    enforce his rules of begging, service and secrecy.” Aple. Br. at 22. On Rule 404(b),
    Piette argues that the molestation evidence fails to show “motive” because the notion
    that Piette’s motive in kidnapping McGinnis was to molest their future children is
    simply the “forbidden character-based propensity inference repackaged.” Aplt. Br. at
    33. Likewise, Piette argues that the molestation evidence fails to show any “plan”
    because it is unrelated to the charged offenses, leaving “no non-propensity purpose.”
    Id. at 35. The government counters that Piette was “motivated to produce children
    16
    Appellate Case: 20-7008      Document: 010110726427       Date Filed: 08/18/2022        Page: 17
    who he could control to meet his sexual desires,” and that kidnapping McGinnis “was
    preparation for his plan to create his own home where he could meet his perverse
    sexual needs” without drawing attention. Aple. Br. at 23–24. Finally, turning to
    Rule 414, Piette argues that the district court failed to conduct a non-conclusory
    prejudicial balancing analysis and that the molestation evidence was barely probative
    but highly prejudicial. The government replies that its admission was a reasonable
    application of Rule 414.
    We review a district court’s evidentiary rulings for abuse of discretion. United
    States v. Sturm, 
    673 F.3d 1274
    , 1285 (10th Cir. 2012). We may uphold them “on any
    ground supported by the record.” 
    Id. at 1286
    . Reversal requires “a distinct showing
    that [the ruling] was based on a clearly erroneous finding of fact, or an erroneous
    conclusion of law or manifests a clear error in judgment.” United States v. Lozado,
    
    776 F.3d 1119
    , 1124 (10th Cir. 2015) (quoting United States v. Smalls, 
    605 F.3d 765
    ,
    773 (10th Cir. 2010)). “When a district court has improperly admitted or excluded
    evidence, we reverse ‘only if the error affects a substantial right of the party.’”

    935 F.3d 960

    b.
    Evidence of other bad acts may be extrinsic or intrinsic depending on its
    relationship to the charged offense. Intrinsic other acts evidence encompasses
    conduct “inextricably intertwined with the charged crime such that a witness’s
    testimony would have been confusing and incomplete without mention of the prior
    act.” United States v. Ford, 
    613 F.3d 1263
    , 1267 (10th Cir. 2010) (quoting United
    States v. Johnson, 
    42 F.3d 1312
    , 1316 (10th Cir. 1994)). This is known as res gestae,
    which the district court invoked to admit much of the molestation evidence. We have
    also described this kind of evidence as “part and parcel of the proof of the offense . . .
    charged in the indictment.” United States v. Kimball, 
    73 F.3d 269
    , 272 (10th Cir.
    1995) (quoting United States v. Gano, 
    560 F.2d 990
    , 994 (10th Cir. 1977)). Res
    gestae evidence is not subject to Rule 404(b), but it remains subject to Rule 403
    balancing and “will be inadmissible . . . if it has no proper probative value.” United
    States v. Irving, 
    665 F.3d 1184
    , 1215 (10th Cir. 2011) (Hartz, J., concurring). In this
    case, a res gestae theory can apply, at most, to the subset of the molestation evidence
    concerning Piette’s daughters. The Springfield girl incident took place before
    McGinnis entered the picture and cannot come in as “part and parcel” of her
    kidnapping. See Kimball, 
    73 F.3d at 272
    .
    In United States v. Ford, the incarcerated defendant and another inmate

    through several prison fences, and rented a getaway car.

    New Mexico, where they sought a new vehicle to avoid detection. 
    Id.
     They were
    arrested while scoping out a local apartment complex for a car to steal, and the
    defendant was charged as a felon in possession, a fugitive in possession, and for
    possession of stolen firearms. 
    Id.
     at 1265–66. On appeal, the defendant challenged
    the trial judge’s admission of evidence concerning his prison escape as res gestae.
    
    Id. at 1267
    . We rejected the defendant’s arguments, concluding that the “Kansas
    escape could not be separated from the charged crimes.” 
    Id. at 1268
    . We reasoned
    that his “flight began with the escape, which explained his need for weapons and the
    circumstances of his arrest just two and a half days later.” 
    Id.
     The evidence was
    “undoubtedly res gestae—intrinsic evidence inextricably connected to the charged
    crimes.” 
    Id.
    Here, the district court properly invoked res gestae to permit the government to
    paint a complete picture of Piette’s other simultaneous domestic molestation conduct.
    Like in Ford, it is difficult to separate Piette’s treatment of his daughters from his
    treatment of McGinnis, especially when McGinnis’s consent was disputed at trial.
    The government used the molestation evidence to reveal the nature of Piette’s
    household and convince the jury that McGinnis never consented to Piette’s treatment.
    See Johnson, 
    42 F.3d at 1316
     (“An uncharged act may not be extrinsic if . . . it was
    part of the scheme for which a defendant is being prosecuted.”). The evidence was
    properly admitted as res gestae, and it is relevant to the finding of fact required to
    rebut Piette’s statute of limitations argument on the kidnapping charge.
    19
    Appellate Case: 20-7008     Document: 010110726427         Date Filed: 08/18/2022      Page: 20
    In his briefing, Piette deletes the references to the abuse of his daughters from
    the government’s account of his behavior, suggesting that such a redlined version
    “would not have left analytical or temporal gaps in the government’s case or left the
    jury confused,” so the res gestae finding was improper. Reply Br. at 5.
    Notwithstanding the logical consistency of Piette’s redacted summary, res gestae was
    still a valid ground for admission because the resulting testimony would have been
    “incomplete” without the evidence of Piette’s abuse of his daughters. See Ford, 
    613 F.3d at 1267
    . It was crucial for the jury to hear from Piette’s daughters about the
    extent of his molestation so it could fully understand their living situation, his
    conduct, his intentions, and McGinnis’s perspective, which they were required to
    evaluate.
    Finding that the intrinsic molestation evidence could come in as res gestae still
    leaves Rule 403 balancing. Under Rule 403, a court “may exclude relevant evidence
    if its probative value is substantially outweighed by a danger of one or more of the
    following: unfair prejudice, confusing the issues, misleading the jury, undue delay,
    wasting time, or needlessly presenting cumulative evidence.” Fed. R. Evid. 403.
    Piette focuses his challenge on the “unfair prejudice” aspect of Rule 403. Typically,
    we review a district court’s Rule 403 analysis to assess whether it constituted an
    abuse of discretion warranting reversal. See, e.g., United States v. Merritt, 
    961 F.3d 1105
    , 1115–16 (10th Cir. 2020). Here, however, the district court’s Rule 403
    analysis was wholly conclusory. Ruling on the molestation evidence orally, the
    district court stated just: “I believe that the probative value of the evidence is
    20
    Appellate Case: 20-7008    Document: 010110726427         Date Filed: 08/18/2022    Page: 21
    certainly not substantially outweighed by the prejudicial effect.” R. Vol. II at 42.
    The district court’s written order had nothing more to say on the matter. That leaves
    little to review. However, we may supplement the district court’s Rule 403
    determination on appeal to assess whether its conclusion was an abuse of discretion.
    See United States v. Magnan, 756 F. App’x 807, 821 (10th Cir. 2018) (unpublished);
    see also Lazcano-Villalobos, 
    175 F.3d at
    846–47.3 Considering Piette’s arguments
    about minimal probative value due to limited areas of dispute at trial, and maximal
    prejudice because of the depravity of the molestation evidence, we conclude that
    Piette understates the evidence’s probative value and overstates its prejudicial effect.
    First, jurors could reasonably find that the molestation evidence made a fact of
    consequence—either McGinnis’s consent, for the kidnapping charge, or Piette’s
    intent, for the traveling-with-intent charge—significantly more or less likely than it
    was without that evidence. See Fed. R. Evid. 401 (relevant evidence has “any
    tendency” to make a “fact . . . of consequence in determining the action” “more or
    less probable”); see also United States v. Jordan, 
    485 F.3d 1214
    , 1218 (10th Cir.
    2007) (the relevancy requirement sets a “very low” bar). For example, by raising
    McGinnis’s consent as a defense, Piette was asking the jury to understand her
    perspective. The molestation evidence helped the jury do so. Piette’s argument that
    McGinnis was unaware of her daughters’ molestation is irrelevant to whether the
    evidence, if believed, made the proposition that she consented less likely. It did, so it
    3
    Unpublished cases are not binding precedent, but we consider them for their
    persuasive value. See Fed. R. App. P. 32.1; 10th Cir. R. 32.1.
    21
    Appellate Case: 20-7008     Document: 010110726427         Date Filed: 08/18/2022     Page: 22
    was relevant. The same is true with respect to Piette’s defense to the traveling-with-
    intent charge. Jurors may have viewed Piette’s later abuse of McGinnis’s daughters
    as making it more likely he had the requisite intent when he traveled with McGinnis.
    Second, while graphic testimony that Piette molested the daughters he had
    with McGinnis may have affected the jury, we do not think that any resulting
    prejudice was particularly unfair or that it substantially outweighed the evidence’s
    probative value with respect to Piette’s principal defenses—or, at least, not so much
    as to render the district court’s decision an abuse of discretion. Piette’s argument
    that jurors may be unfairly inflamed by child sexual predators is somewhat self-
    defeating. Even before hearing from Ma.P. and A.P., the jurors were already dealing
    with an individual charged with kidnapping his preteen stepdaughter-wife, raping her
    three times a day for years, and forcing her to bear nine of his children. The district
    court could have reasonably concluded that any prejudicial effect probably would
    have already happened. Even defense counsel started his opening statement at trial
    by saying: “Ladies and gentlemen of the jury, [the government’s] opening statement,
    it sounds real bad, it sounds awful.” R. Vol. II at 98. In light of this, the district
    court could have also recognized, as a countervailing consideration, that it was
    important for the jury to hear the molestation evidence. As we have explained, the
    evidence served a critical purpose: it helped the jury contextualize McGinnis’s
    situation and assess whether Piette’s defenses were meritorious. Because the district
    court could have reasonably concluded that the danger of unfair prejudice did not
    outweigh the molestation evidence’s probative value, it was not an abuse of
    22
    Appellate Case: 20-7008     Document: 010110726427         Date Filed: 08/18/2022    Page: 23
    discretion to admit the subset of the molestation evidence concerning Piette’s
    daughters, notwithstanding Rule 403.
    c.
    The government recognized at trial that Tobias’s testimony about Piette
    molesting the Springfield girl was inadmissible as res gestae because it preceded
    Piette’s time with McGinnis. In other words, it was extrinsic bad acts evidence.
    However, the government argued that Rules 404(b) and 414 were alternative bases
    for admission. We hold that even if the district court erred by admitting this subset
    of the molestation evidence under either rule, any error was harmless.
    Evidence law generally abhors the propensity inference—the notion that a
    person did something just because he has a corresponding character or has done
    similar things before. See Fed. R. Evid. 404(b)(1) (“Evidence of any other crime,
    wrong, or act is not admissible to prove a person’s character in order to show that on
    a particular occasion the person acted in accordance with the character.”); see also
    Michelson v. United States, 
    335 U.S. 469
    , 475–76 (1948). However, Rule 404(b)
    carves a purpose-based exception that allows evidence of other bad acts to be
    admitted for non-propensity purposes, “such as proving motive, opportunity, intent,
    preparation, plan, knowledge, identity, absence of mistake, or lack of accident.” Fed.
    R. Evid. 404(b)(2). “We ‘consider four factors in weighing the admissibility of
    evidence under Rule 404(b): (1) whether the evidence is offered for a proper purpose,
    (2) its relevancy, (3) that the probative value of the evidence is not substantially
    outweighed by its prejudicial effect, and (4) [that] a limiting instruction is given if
    23
    Appellate Case: 20-7008      Document: 010110726427       Date Filed: 08/18/2022      Page: 24
    the defendant so requests.’” United States v. Burgess, 
    576 F.3d 1078
    , 1098 (10th Cir.
    2009) (quoting United States v. Mares, 
    441 F.3d 1152
    , 1157 (10th Cir. 2006)). This
    inquiry incorporates the Rule 401 relevancy and Rule 403 balancing inquiries at steps
    two and three, respectively. See United States v. Tan, 
    254 F.3d 1204
    , 1207 (10th Cir.
    2001).
    Another exception to the general inclination against propensity evidence is
    Rule 414, which embraces the propensity inference in a limited class of cases. It
    states that, “[i]n a criminal case in which a defendant is accused of child molestation,
    the court may admit evidence that the defendant committed any other child
    molestation . . . on any matter to which it is relevant.” Fed. R. Evid. 414(a). There
    are three “threshold requirements” for admitting evidence pursuant to Rule 414:
    “(1) the defendant is accused of a crime involving sexual assault or child molestation,
    (2) the evidence proffered is evidence of the defendant’s commission of another
    offense or offenses involving sexual assault or child molestation, and (3) the
    evidence is relevant.” United States v. Benally, 
    500 F.3d 1085
    , 1090 (10th Cir.
    2007). But that is not the end of the road. We subject Rule 414 evidence to a
    particular breed of Rule 403 balancing and insist that “the district court has an
    obligation ‘to fully evaluate the proffered . . . evidence and make a clear record of the
    reasoning behind its findings.’” 
    Id. at 1091
     (omission in original) (quoting United
    States v. Guardia, 
    135 F.3d 1326
    , 1331 (10th Cir. 1998)).4
    4
    This specialized Rule 403 inquiry has two stages. First, the district court
    must consider the four Enjady factors: “(1) how clearly the prior act has been proved;
    24
    Appellate Case: 20-7008    Document: 010110726427        Date Filed: 08/18/2022       Page: 25
    Even if the district court erred by admitting the subset of the molestation
    evidence concerning the Springfield girl under Rules 404(b) or 414, we think that any
    such error was harmless. Reviewing the record in its entirety makes clear that
    testimony about the Springfield incident occupied only a few moments in a weeklong
    trial packed with graphic, disturbing evidence of Piette’s behavior, often in the form
    of lengthy firsthand accounts from survivors like McGinnis, Ma.P., and A.P. Tobias
    Piette’s testimony about encountering Piette and the Springfield girl in the shower
    before meeting McGinnis pales in comparison to the breadth, depth, and detail of the
    remaining sexual molestation evidence the jury heard in this case. It is also notable
    that the jury received evidence of inappropriate conduct with minors unrelated to
    McGinnis, her children, or the Springfield girl, which Piette does not challenge on
    appeal, such as the driving lesson Tobias testified about. Based on our review of the
    questions the jury was asked to decide, and the evidence the government presented to
    help it decide them, we think it is more likely than not the case, see Burke, 935 F.3d
    at 1011, that the subset of the molestation evidence involving the Springfield girl,
    even if admitted in error, had no effect on the jury’s verdict on either count. Because
    (2) how probative the evidence is of the material fact it is admitted to prove; (3) how
    seriously disputed the material fact is; and (4) whether the government can avail
    itself of any less prejudicial evidence.” United States v. Perrault, 
    995 F.3d 748
    , 765–
    66 (10th Cir. 2021) (footnotes omitted); see also United States v. Enjady, 
    134 F.3d 1427
    , 1433 (10th Cir. 1998). The district court must next weigh the Enjady factors
    against three additional factors: “(1) how likely [it is that] such evidence will
    contribute to an improperly-based jury verdict; (2) the extent to which such evidence
    will distract the jury from the central issues of the trial; and (3) how time consuming
    it will be to prove the prior conduct.” Perrault, 995 F.3d at 766.

    Piette fails to demonstrate that the admission of this subset of the molestation
    evidence affected the case, we need not consider whether the evidence was properly
    admitted under Rules 404(b) or 414.
    ***
    The molestation evidence concerning Piette’s daughters was properly admitted
    as res gestae, and any error in admitting the remaining molestation evidence
    involving the Springfield girl was harmless. The district court’s conclusory Rule 403
    assessment does not require reversal because, on this record, it was not an abuse of
    discretion to find that the evidence’s probative value was not outweighed by its
    prejudicial effect. See Lazcano-Villalobos, 
    175 F.3d at
    846–47.
    III.
    Next, we consider Piette’s argument that the traveling-with-intent charge was
    brought outside the statute of limitations because the enactments purporting to extend
    the then-unexpired charging period had an impermissible retroactive effect. We
    review the district court’s “interpretation and application” of statutes of limitations
    de novo. Barnes v. United States, 
    776 F.3d 1134
    , 1139 (10th Cir. 2015). We
    likewise review the retroactivity of a statute de novo. See Valdez-Sanchez v.
    Gonzales, 
    485 F.3d 1084
    , 1088 (10th Cir. 2007). For the following reasons, we
    reject Piette’s argument and affirm his traveling-with-intent conviction.
    The general federal statute of limitations for noncapital offenses is five years.
    See

    limitations that apply to Piette’s traveling-with-intent charge have gone through a
    series of changes in the past few decades, as summarized below.

    Safety Act
    Today, both §§ 3283 and 3299 cover Piette’s traveling-with-intent charge.
    Piette argues that the statute of limitations on that charge began to run, at the latest,
    on May 14, 2000, when McGinnis turned sixteen. See id. § 2243(a) (criminalizing
    sexual acts with minors between twelve and sixteen by persons at least four years
    older). At that point, the statute of limitations in effect—§ 3283 (1994)—would
    expire on McGinnis’s twenty-fifth birthday, which was May 14, 2009. Piette was
    ultimately charged in December 2017. Before the limitations period expired,
    however, Congress made the 2003 and 2006 changes outlined above, which would
    render Piette’s indictment timely if applied to him.
    The issue is whether the new statutes of limitations validly extended the
    charging period for Piette’s pre-enactment conduct—that is, whether they apply
    27
    Appellate Case: 20-7008    Document: 010110726427         Date Filed: 08/18/2022    Page: 28
    retroactively. Piette argues that the test outlined by the Supreme Court in Landgraf
    v. USI Film Products, 
    511 U.S. 244
    , 280 (1994), and Fernandez-Vargas v. Gonzales,
    
    548 U.S. 30
    , 37 (2006), for assessing a statute’s retroactivity requires reversal and
    renders his indictment untimely. Piette is not the first defendant to encounter this
    problem or make this argument. Several courts have discussed this exact question
    either on the merits or in the context of an ineffective assistance of counsel claim.
    See Weingarten v. United States, 
    865 F.3d 48
    , 54–58 (2d Cir. 2017) (ineffective
    assistance); United States v. Miller, 
    911 F.3d 638
    , 642–46 (1st Cir. 2018) (ineffective
    assistance); United States v. Nader, 
    425 F. Supp. 3d 619
    , 624–32 (E.D. Va. 2019)
    (merits); United States v. Maxwell, 
    534 F. Supp. 3d 299
    , 314–16 (S.D.N.Y. 2021)
    (merits). These cases inform our determination whether the relevant statutes of
    limitations apply retroactively, which appears to be a question of first impression in
    this circuit.
    At the outset, it is important to clarify the Landgraf framework that guides our
    review. Different circuits divide on the proper number of steps and their contents,
    but we tend to view Landgraf as a two-step process. See Dobbs v. Anthem Blue
    Cross & Blue Shield, 
    600 F.3d 1275
    , 1282–83 (10th Cir. 2010). First, we ask
    “whether Congress has expressly prescribed the proper reach” of the statute. 
    Id. at 1282
    . If so, we follow Congress’s lead. If not, we proceed to the second step, asking
    “whether applying the statute to the events at issue would have retroactive effects.”
    
    Id.
     The Supreme Court instructs that “[s]tatutes are disfavored as retroactive when
    their application ‘would impair rights a party possessed when he acted, increase a
    28
    Appellate Case: 20-7008     Document: 010110726427        Date Filed: 08/18/2022        Page: 29
    party’s liability for past conduct, or impose new duties with respect to transactions
    already completed.’” Fernandez-Vargas, 
    548 U.S. at 37
     (quoting Landgraf, 
    511 U.S. at 280
    ). If we find a retroactive effect, “our traditional presumption teaches that it
    does not govern absent clear congressional intent favoring such a result.” Landgraf,
    
    511 U.S. at 280
    .
    Before proceeding, we note that Piette is not making an Ex Post Facto Clause
    argument. See U.S. Const. art. I, § 3, cl. 9. Several circuits have analyzed this exact
    issue under that rubric, as opposed to Landgraf retroactivity, and declined to find a
    violation of the Ex Post Facto Clause where the amended statute of limitations
    merely extended, as opposed to revived, a charging period. See United States v.
    Chief, 
    438 F.3d 920
    , 924–25 (9th Cir. 2006); United States v. Jeffries, 
    405 F.3d 682
    ,
    685 (8th Cir. 2005).
    At Landgraf’s first step, we look for an express indication of the statutes’
    temporal reach. The argument on the government’s side is that the statutes’
    introductory clauses—“[n]o statute of limitations that would otherwise preclude,” for
    § 3283, and “[n]otwithstanding any other law,” for § 3299—supply a “clear statement
    as to . . . retroactive effect.” Weingarten, 865 F.3d at 55. A district court accepting
    this argument with respect to § 3283 reasoned that “[t]he statute’s plain language
    unambiguously requires that it apply to prosecutions for offenses committed before
    the date of enactment . . . [because] it prevents the application of any statute of
    limitations that would otherwise apply to past conduct.” Maxwell, 534 F. Supp. 3d at
    29
    Appellate Case: 20-7008     Document: 010110726427         Date Filed: 08/18/2022     Page: 30
    315. The same reasoning would apply to § 3299’s “[n]otwithstanding any other law”
    language, which casts an even wider net.
    The counterargument is that this introductory language refers not to
    retrospective application, but only to 
    18 U.S.C. § 3282
    (a), the general federal statute
    of limitations. On this reading, the statutes are merely supplanting the typical five-
    year charging period. The First Circuit has observed that when this introductory
    language was first deployed in § 3283 in 1990, “the only existing limitations period
    to which the language could have referred was the default limit set forth in section
    3282.” Miller, 911 F.3d at 644. Moreover, other statutes with the same kind of
    introductory language contain explicit retroactivity provisions, so the government’s
    interpretation would render them redundant.
    Piette’s position points to the “express” requirement in Landgraf’s first step
    and argues that it creates a high bar §§ 3283 and 3299 cannot meet. See Nader, 425
    F. Supp. 3d at 626 (referencing “the demanding standard for express prescription” in
    the Fourth Circuit, which requires “language unequivocally delineating the time
    period to which [statutes] apply”). It is indisputable that these statutes say nothing
    express about retroactive application, so Piette has the stronger argument on this
    point. Although the introductory words of both statutes are not inconsistent with the
    government’s reading, they hardly constitute Congress expressly announcing a
    retroactive effect. A provision literally stating that a statute applies retroactively is
    more so the kind of provision that Landgraf contemplates. Congress can enact, and
    30
    Appellate Case: 20-7008    Document: 010110726427         Date Filed: 08/18/2022     Page: 31
    has enacted, such provisions in the past. But it did not do so in either § 3283 or
    § 3299. We proceed to Landgraf’s second step.
    At this step, we look for an impermissible retroactive effect, defined as an
    effect that “would impair rights a party possessed when he acted, increase a party’s
    liability for past conduct, or impose new duties with respect to transactions already
    completed.” Landgraf, 
    511 U.S. at 280
    . If we find such an effect, we presume the
    statute does not apply retroactively unless there is “clear congressional intent
    favoring such a result.” 
    Id.
    On Piette’s side, the Second Circuit has acknowledged “colorable arguments”
    that extending a live charging period would increase a defendant’s liability for past
    conduct under Landgraf. See Weingarten, 865 F.3d at 57. But the court also
    acknowledged that the “vast weight of retroactivity decisions” support a distinction
    “between revoking a vested statute of limitations defense and extending a filing
    period for live claims.” Id. The former would be a problem. The latter would not.
    The First Circuit notes that the question’s difficulty is compounded by the criminal
    context. See Miller, 911 F.3d at 645. After all, the Supreme Court has held that
    statutes of limitations should be “liberally interpreted in favor of repose.” Toussie v.
    United States, 
    397 U.S. 112
    , 115 (1970). Accordingly, Piette relies heavily on
    United States v. Gentile, which held that a different statute of limitations extension
    was impermissibly retroactive under Landgraf because of that very principle. 
    235 F. Supp. 3d 649
    , 654 (D.N.J. 2017). But other courts have distinguished Gentile,
    concluding that “the case law strongly supports the proposition that the distinction
    31
    Appellate Case: 20-7008     Document: 010110726427        Date Filed: 08/18/2022        Page: 32
    between applying a statute that extends or eliminates a statute of limitations period to
    claims that were expired at the time of its enactment, and applying it to claims that
    were unexpired at the time of its enactment, is applicable to both civil and criminal
    statutes of limitations.” Nader, 425 F. Supp. 3d at 630.
    We agree. In 2003 and 2006, when these statutes of limitations were enacted,
    the original statute of limitations had not yet expired and Piette remained subject to
    prosecution for his past conduct insofar as he was susceptible to being charged for it.
    By extending the unexpired statute of limitations, Congress did not increase Piette’s
    exposure to prosecution retroactively. It did not raise the penalty for the charged
    offense. It did not redefine the offense to make it easier to establish. It did not
    expose Piette to criminal prosecution anew. It merely altered the ongoing charging
    period for the conduct that had already exposed him to criminal prosecution. Piette
    was subject to indictment in 2002, before the statutes of limitations were extended,
    and he remained subject to indictment in 2007, once the changes were made. A dead
    charge was not resurrected, and the underlying nature of Piette’s potential criminal
    liability remained the same. Ex Post Facto Clause cases echo both this conclusion
    and the import of this distinction in the broader retroactivity context. See, e.g.,
    Jeffries, 
    405 F.3d at 685
    . Piette’s argument that he had the “statutory right,” Aplt.
    Br. at 51 (quoting Gentile, 
    235 F. Supp. 3d at 654
    ), to be free from prosecution after
    the original statute of limitations would have expired is misguided. Rather, it is
    Congress that had the right to modify a pending statute of limitations. Doing so does
    not violate retroactivity principles with respect to unexpired charging periods. We
    32
    Appellate Case: 20-7008      Document: 010110726427         Date Filed: 08/18/2022      Page: 33
    conclude that neither statute of limitations had an impermissible retroactive effect
    because the relevant charging period had not yet expired. Extending an unexpired
    statute of limitations does not increase a defendant’s exposure to prosecution. As a
    result, we need not consider Congressional intent. Landgraf is no basis for finding
    Piette’s traveling-with-intent charge untimely, so we affirm the conviction.
    IV.
    Finally, we consider Piette’s argument that his kidnapping conviction should
    be reversed. We agree and reverse Piette’s kidnapping conviction because the
    district court plainly erred by misallocating the burden of proof in its jury
    instructions and verdict form. We review the kidnapping jury instruction for plain
    error because Piette failed to object to it below. See United States v. Antonio, 
    936 F.3d 1117
    , 1126 (10th Cir. 2019). To prevail on plain error review, Piette must show
    that “(1) the district court erred, (2) the error was plain, (3) the error affected
    substantial rights, and (4) the error seriously affected the fairness, integrity, or public
    reputation of judicial proceedings.” United States v. Muñoz, 
    812 F.3d 809
    , 813 (10th
    Cir. 2016).
    Our precedent clarifies how plain error analysis should be approached when a
    jury instruction is under review. First, an instruction amounts to error where,
    “considering the instructions as a whole, the jury has been misled.” United States v.
    Duran, 
    133 F.3d 1324
    , 1330 (10th Cir. 1998). Second, an error is plain where it is
    “clear or obvious.” Muñoz, 812 F.3d at 813 (quoting Morales-Fernandez v. INS, 
    418 F.3d 1116
    , 1124 (10th Cir. 2005)). Third, an instruction affects substantial rights if it
    33
    Appellate Case: 20-7008     Document: 010110726427         Date Filed: 08/18/2022     Page: 34
    “concerns a principal element of the defense or an element of the crime.” Duran, 
    133 F.3d at 1330
    . Finally, “the fairness or integrity of a defendant’s trial is seriously
    affected when the defendant has presented substantial evidence in support of an
    affirmative defense which has been undermined by an erroneous instruction.” 
    Id.
    (internal quotation marks omitted).
    A criminal defendant generally bears the burden of proof on affirmative
    defenses, but Piette relies upon Supreme Court authority suggesting a consensus
    around the proposition that when a defendant contests whether the statute of
    limitations has run, the burden of proof on that issue shifts to the government. Piette
    argues that the district court plainly erred by instructing the jury that he bore the
    burden to prove that McGinnis was no longer held against her will at a certain date,
    an argument that would have started the statute of limitations on the kidnapping
    charge. To surmount the “extremely high hurdle” set by plain error review, United
    States v. Walser, 
    275 F.3d 981
    , 988 (10th Cir. 2001), Piette cites to United States v.
    Duran, a case involving the entrapment defense, which is subject to a similar burden-
    shifting treatment. In Duran, we found reversible plain error under nearly identical
    procedural circumstances. 
    133 F.3d at
    1329–34.
    Starting with Supreme Court precedent, in Musacchio v. United States the
    Court held that the general federal criminal statute of limitations, 
    18 U.S.C. § 3282
    (a), cannot be raised on appeal unless it was argued below. 
    577 U.S. 237
    , 248
    (2016). The Court explained:
    34
    Appellate Case: 20-7008     Document: 010110726427        Date Filed: 08/18/2022      Page: 35
    [A] statute-of-limitations defense becomes part of a case only if the
    defendant puts the defense in issue. When a defendant presses a
    limitations defense, the Government then bears the burden of establishing
    compliance with the statute of limitations by presenting evidence that the
    crime was committed within the limitations period or by establishing an
    exception to the limitations period.
    
    Id.
     (emphasis added) (citing United States v. Cook, 
    17 Wall. 168
    , 179 (1872)). We
    have previously relied upon this aspect of Musacchio. See United States v. DeLia,
    
    906 F.3d 1212
    , 1217 (10th Cir. 2018) (when defendant “affirmatively and timely”
    raises statute-of-limitations defense, burden shifts to government to establish
    compliance). Other circuits agree. See United States v. Wilson, 
    118 F.3d 228
    , 236
    (4th Cir. 1997); United States v. Ferris, 
    807 F.2d 269
    , 272 (1st Cir. 1986).
    The government relies upon Smith v. United States, 
    568 U.S. 106
     (2013),
    which held that assigning the burden of proving withdrawal from a conspiracy to a
    defendant does not violate the Due Process Clause, to argue that it does not need to
    prove the nonexistence of affirmative defenses. The district court also cited Smith in
    a pretrial order on this issue. See R. Vol. I at 152 (“Commission of a federal crime
    within the statute-of-limitations period is not an element of the offense, and it is up to
    the defendant to raise the limitations defense.”). But, as Piette points out, the Court
    in Smith expressly stated “that the Government must prove the time of the conspiracy
    offense if a statute-of-limitations defense is raised.” 
    568 U.S. at 113
    . Smith is
    consistent with both Musacchio and Piette’s theory of plain error.
    It is therefore settled that if a defendant invokes the statute of limitations as a
    defense, the burden shifts to the government to establish the timing of the offense
    35
    Appellate Case: 20-7008     Document: 010110726427        Date Filed: 08/18/2022     Page: 36
    beyond a reasonable doubt. Here, by instructing the jury to the contrary, the district
    court misled the jury and committed plain error. Significant daylight divides the
    jury’s finding that Piette failed to show, by a preponderance of the evidence, that
    McGinnis was no longer held against her will at any point between 1997 and 2016,
    from the hypothetical finding Piette requests, and which we hold the Constitution
    requires: that the government proved, beyond a reasonable doubt, that McGinnis was
    continuously held against her will long enough to avoid any statute of limitations
    problem.
    Turning to the remaining elements of plain error review, we observed in Duran
    that a jury instruction affects a defendant’s substantial rights where it involves a
    “principal element[]” of a defense. 
    133 F.3d at 1333
    . Here, Piette predicated his
    entire defense to the kidnapping charge upon McGinnis’s consent. Shifting the
    burden of proof to the government was a crucial aspect of the defense’s efficacy.
    Also, the district court seemed to understand that whether McGinnis consented
    affected the viability of the kidnapping charge on the very statute of limitations
    grounds urged by Piette on appeal. See R. Vol. I at 372 (“This will aid the court in
    making a separate legal determination in regard to this case.”). The district court’s
    plain error regarding the burden of proof affected Piette’s substantial rights because it
    involved a principal element of Piette’s principal defense. See Duran, 
    133 F.3d at 1333
    .
    Finally, we held in Duran that “[i]n light of the revered status of the beyond-a-
    reasonable-doubt standard in our criminal jurisprudence, a jury instruction that
    36
    Appellate Case: 20-7008     Document: 010110726427        Date Filed: 08/18/2022     Page: 37
    allows a conviction where one important element may not have been found against
    the defendant by such a standard cannot be overlooked.” 
    Id. at 1334
    . That is exactly
    what happened here. The timing issue created by Piette’s defense was not resolved
    beyond a reasonable doubt, as the Constitution requires. The district court plainly
    erred, so Piette’s kidnapping conviction must be reversed.5
    V.
    Last, because we affirm the traveling-with-intent conviction, we reach and
    reject Piette’s constitutional challenge to his sentence for that conviction. Piette
    argues that, even if any of his convictions are not overturned, his sentence should be
    reversed because he was denied his Sixth Amendment right to represent himself at
    sentencing. A defendant seeking to represent himself must (1) “clearly and
    unequivocally” inform the court; (2) do so “timely and not for the purpose of delay”;
    (3) assure the court that he is waiving the right to counsel “knowingly and
    intelligently”; and (4) be “able and willing to abide by rules of procedure and
    courtroom protocol.” United States v. Simpson, 
    845 F.3d 1039
    , 1046 (10th Cir.
    2017) (quoting United States v. Tucker, 
    451 F.3d 1176
    , 1180 (10th Cir. 2006)). We
    5
    In the closing moments of his rebuttal at oral argument, Piette’s counsel
    suggested that “the fundamental nature of the burden of proof” requires reversing
    Piette’s traveling-with-intent conviction because of the error that requires overturning
    his kidnapping conviction. Oral Arg. at 32:28–32:37. We do not consider issues that
    are first presented at oral argument. See Denver Homeless Out Loud v. Denver, 
    32 F.4th 1259
    , 1269 n.9 (10th Cir. 2022).
    37
    Appellate Case: 20-7008     Document: 010110726427        Date Filed: 08/18/2022     Page: 38
    review the district court’s failure to allow Piette to represent himself at sentencing for
    abuse of discretion.6
    Piette argues that the district court should have conducted a Faretta hearing
    and allowed him to represent himself at sentencing. See Faretta v. California, 
    422 U.S. 806
    , 834–36 (1975); see also United States v. Hansen, 
    929 F.3d 1238
    , 1249
    (10th Cir. 2019) (district courts often assess whether waivers of counsel are made
    knowingly and intelligently by conducting Faretta hearings). The government
    responds that Piette failed to make a clear and unequivocal request to proceed pro se
    because of his “prolific and varied correspondence with the district court,” which
    alternated between praising and lambasting his attorney, Warren Gotcher. Aple. Br.
    at 46. The government also observes that, at sentencing, Piette agreed to Gotcher
    representing him through filing an appeal, and that Piette spoke extensively on his
    own behalf. We agree with the government. Piette’s theory fails on the clear-and-
    unequivocal prong for two principal reasons, and therefore the district court did not
    abuse its discretion.
    6
    Both parties misstate the standard of review as de novo, which ignores the
    distinction we draw between requests for self-representation made before trial,
    reviewed de novo, and requests made after trial, reviewed for abuse of discretion.
    See United States v. Beers, 
    189 F.3d 1297
    , 1303 (10th Cir. 1999); see also United
    States v. Estrada, 25 F. App’x 814, 819–20 (10th Cir. 2002) (unpublished). Piette
    focuses on demands for counsel’s withdrawal made in November 2019 and renewed
    at sentencing in February 2020. The jury reached its verdict on June 6, 2019, ending
    the trial months before Piette’s first supposed request to proceed pro se. Because any
    invocation of the right to self-representation would have occurred post-trial, we
    review for abuse of discretion.

    First, it is neither clear nor unequivocal that Piette ever sought to represent
    himself—as opposed to merely requesting to withdraw Gotcher and receive new
    appointed counsel. Only the former endeavor would implicate Piette’s constitutional
    right to self-representation. On appeal, Piette argues that his November 2019 letter
    did not request a replacement attorney, so we should view it as a request for self-
    representation. But, by the same reasoning, the letter said nothing about self-
    representation or proceeding pro se. Although it was preceded by a handwritten
    pleading, Piette submitted numerous such documents while represented by counsel.
    Similarly, Piette’s request for case materials could have been an attempt to recover
    personal documents for his own records or for use by his next attorney, and not an
    implicit request for self-representation. Moreover, Piette based his request on
    Gotcher’s ineffective assistance and not on any constitutional right to self-
    representation. In his response to Piette’s motion, Gotcher requested that Piette “be
    appointed new counsel for appeal unless the defendant employs his own counsel,
    which Counsel advised the defendant is his right.” R. Vol. I at 407. Gotcher, who
    had contemporaneous personal access to Piette, did not even address the possibility
    that Piette contemplated proceeding pro se at sentencing.
    Second, even if Piette was attempting to invoke his right to self-representation
    for purposes of sentencing, he verbally assented to the district court’s contrary
    determination. Specifically, the district court asked Piette whether withdrawing
    counsel post-sentencing was “acceptable.” R. Vol. II at 1108. Piette’s “[y]es, sir,
    yes” response is as notable for what it says as what it does not say. Id. at 1109.

    Between hundreds of pages of letters to the district court and a lengthy statement at
    sentencing, Piette did not hesitate to share his perspective with the court. The
    absence of any statement by Piette about self-representation undercuts his claim to
    clarity on appeal. If Piette wanted to represent himself, he probably would have said
    something to that effect, especially when given the opportunity.
    The district court granted Piette’s motion without a Faretta hearing not
    because the court thought it was allowing Piette to proceed pro se, but because it did
    not view the circumstances as implicating Faretta. It reasonably thought Piette
    wanted new counsel, not self-representation, and Piette said nothing to suggest
    otherwise. We do not know the contents of the off-the-record conversation between
    Piette and Gotcher alluded to in the hearing transcript, but if Piette wanted to proceed
    pro se—a different request from just withdrawing Gotcher—it likely would have
    come before the court. Piette may be correct that no magic words are required to
    invoke the right to self-representation, but courts cannot read minds. The clear-and-
    unequivocal requirement exists in part to “protect . . . the trial court” from a reversal
    “dilemma” where a defendant granted counsel can assert a violation of the right to
    proceed pro se, while a defendant granted self-representation can assert a violation of
    the right to counsel. Simpson, 845 F.3d at 1046–47. Here, Piette clearly and
    unequivocally requested only that his counsel be withdrawn, and the district court
    granted that request. Because there was no clear and unequivocal request that
    Gotcher withdraw so that Piette could represent himself at sentencing, and because

    Piette assented to the district court’s contrary ruling, the court did not abuse its
    discretion.
    VI.
    We AFFIRM Piette’s traveling-with-intent conviction, REVERSE Piette’s
    kidnapping conviction, reject Piette’s constitutional attack on his sentencing, and
    REMAND for further proceedings consistent with this opinion.
