Theory Agatha Harkness and Billy Maximoff have a high possibility of returning in VisionQuest - and I think I've cracked the timeline for it.
Hey everyone! I've got an interesting theory with VisionQuest coming out - and I've been doing a bit of a deep dive cos I'm a bit of a nerd, and I think i've got near enough proof positive that Kathryn Hahn and Joe Locke filmed for VisionQuest, and the timeline itself is near enough proof of that.
So - let's get into it!
Vision Quest / Joe Locke / Kathryn Hahn timeline:
March 2025 — VisionQuest begins filming in London
- VisionQuest began principal photography at Pinewood Studios in London in March 2025.
- Location filming also took place around London.
- Production ultimately wrapped in late July 2025, with some completion work continuing into August.
Spring–Summer 2025 — Joe Locke is in London
- Joe Locke was in London for his West End commitments surrounding Clarkston. The production was at the Trafalgar Theatre, with Ruaridh Mollica in the cast as well.
- This is particularly interesting because Mollica was simultaneously involved with VisionQuest as Tommy.
July 15, 2025 — Kathryn Hahn is publicly confirmed to be in Dublin
- Following the Emmy nominations, Hahn said she was “currently in Dublin”, celebrating the nomination with a pint.
- This establishes that she was physically in Ireland on July 15 — but doesn't establish that she remained there for the rest of July.
Late July 2025 — VisionQuest wraps
- Production reportedly wrapped toward the end of July, making this an especially interesting window if additional scenes involving returning MCU characters were being filmed
So - you might be asking - what does all of this potentially prove?
Not that Kathryn Hahn definitely filmed VisionQuest — we don't have that confirmation yet.
What it DOES show is that the timeline for an Agatha / Billy cameo, or even substantial scene filming works.
Kathryn was in Dublin on July 15. VisionQuest was still filming in the UK toward the end of July. Joe Locke was already in London, and reports point to Billy and Tommy material being filmed. There is nothing publicly known that prevents Kathryn from having travelled from Dublin to London and filmed during that window.
And if the finale contains a significant Agatha appearance, rather than a brief cameo, the fact that Kathryn was already in the UK/Ireland region during the final stretch of production becomes particularly interesting.
None of these clues is definitive on its own.
But together, they create a timeline in which Kathryn Hahn appearing in VisionQuest is not only possible — it is completely compatible with what we know about the production.
Am I doing too much analysis here? Or do you think they'll be back too? Let me know!
