The latest Marvel Cinematic Universe TV series Agatha Always Alreadywhich premiered this week on Disney+, is the result of WandaVisionanother MCU show where magic and mystery went hand in hand. In WandaVisionthe central question was how Elizabeth Olsen’s Wanda Maximoff and Paul Bettany’s Vision would end up as a married couple in an ever-changing sitcom reality, as Vision, you know, dead on the screen in Infinity War (and not in a reversible, Thanos-snap kind of way.)

WandaVision ended with its primary antagonist Agatha Harkness (Kathryn Hahn) trapped in her own sitcom-verse, so one question Agatha Always Already must answer in the first episodes, which go into more depth Mare of Easttown the road WandaVision immersed in family sitcoms, in which Agatha plays the role of a seasoned detective, is how she gets out of it and returns to reality.

But at the end of the first two episodes, which dropped on Disney+ last night, another question looms: Who the heck is “Teen,” the character played by Heart Conqueror star Joe Locke, and what is his significance to the broader story of the Marvel Universe?

Yes, you read that right—for now, at least, Locke’s character name is “Teen.” That’s what Agatha calls him after she discovers that he’s incapable of explaining his true nature. Someone or something has cast a spell on Teen that prevents him from revealing anything about himself; the first time he tries, a thread appears over his face and sews his mouth shut. Later, in episode two, the audio cuts out when he tries to tell his backstory; Agatha turns up the radio to make sure her hearing doesn’t give her away.

Of course, the fact that a magical force doesn’t want it—and by extension the audience—to know the true identity of Locke’s character has only fueled speculation about who he’s really supposed to be. The most likely explanation? He’s a grown-up version of Wanda’s son Billy, who audiences last saw in WandaVision. Billy’s costume in the Halloween episode of that show may have been a nod to his eventual future: in Marvel’s comic book continuity, a reincarnated Billy becomes Wiccan, a teenage superhero with reality-warping powers similar to his mother’s. Created by Allan Heinberg and Jim Cheung in the series Young AvengersWiccan was also one of Marvel’s first prominent gay characters (possibly reflected in Agatha(We see a teenager who at one point avoids a phone call from his boyfriend.)

Locke’s Teen seems a lot like Billy/Wiccan, and given how intertwined WandaVision And Agatha Always Already are, if this isn’t intentional foreshadowing, then it’s intentional misdirection. Of course, it’s possible that Teen is Wiccan, but not Billy. In the first episode, there’s a short teaser with a character named Nicholas Scratch, who Agatha‘s son in the comics. Narratively, it makes more sense for Agatha to be paired with her own son rather than Wanda’s; it would add personal stakes to Agatha’s journey while preparing Wiccan to appear in a potential Young Avengers film, for which Marvel has already laid the groundwork by introducing Iman Vellani’s Kamala Khan and Hailee Steinfeld’s Kate Bishop.

But to find out for sure, we’ll have to join Hahn, Locke and the rest of the all-star cast on their magical nine-episode mystery tour.
