Warning! This article contains major spoilers for Agatha All Along episodes 1 to 6.
Well, we pretty much know exactly who Teen is now. The past two episodes of the WandaVision spin-off show have revealed all, from his new identity as Wiccan to how exactly Billy Maxmioff ended up in his body. We even know what's motivating him on his journey down the Witches' Road, too. Yep, it's a lot to take in. Well, that's where we come in as we've taken a deep dive into all of the details gleaned about Teen/William Kaplan/Billy Maximoff/Wiccan so far.
With everything from connections to some famous MCU characters to how he ended up back in Westview revealed, there is plenty to sort through as well. Below we break it all down, diving into who Teen really is...
Is Teen actually Billy Maximoff AKA Wiccan?
We can now answer this with a resounding 'yes' as the end of Agatha All Along episode 5 revealed that Teen is indeed Wanda's son Billy, who goes by 'Wiccan' in the Marvel comics.
In 'Darkest Hour, Wake Thy Power', the coven went through their next trial along the Witches' Road, where they learned more about Agatha's dark past. It was a pretty dramatic chapter that saw Agatha become possessed after using a Ouija board, leading to Alice trying to save her. However, in the process Agatha claims Alice's powers, which looks to kill Ali Ahn's witch.
An upset Teen attempts to wake Alice but has no luck, with the coven telling him that she's gone. He then turns on Agatha, confronting her about Alice's death, questioning whether being a witch means killing people to serve your own agenda. As Teen says that way is not for him, a snarling Agatha replies with: "Are you sure? You're so much like your mother!" Angering Teen further, he retaliates by sinking Agatha and the rest of the remaining members of the coven into the ground, using the blue magic emanating from his hands.
Then it happens – as the Billie Eilish song 'You Should See Me In A Crown' plays (nice touch, Disney) an ornate crown similar to the one Wanda wears magically appears on Teen's head, which we can take as confirmation that he is Billy Maximoff, AKA Wiccan.
Agatha All Along episode 6 then took audiences on 50-minutes-long deep dive into how he ended up here. We first meet Teen in this episode as William Kaplan, a young boy celebrating his bar mitzvah with his parents when he encounters a strange witch. Yep, it's Lilia giving out fortunes at the party. She predicts an upcoming split in the boy's life, while examining his palm during a reading, and decides to put a sigil on him so he doesn't remember any witches, and he isn't able to tell them his real identity.
On the car drive home, we learn that the "Westview anomaly" is playing up, before William's parents crash their car into a tree. He's killed in the collision and this is when Billy Maximoff's soul transfers into his body, bringing him back to life – but changed.
Over the next three years, Billy tries to fit into William's life, but he's uneasy with who he really is. Some in-depth internet research (well, Reddit) takes him into the path of Ralph Bohner who reveals some key information about the Maximoff twins and Agatha Harkness. We're getting up to the present day now, as Billy heads to meet Agatha and convince her to take him to the Witches' Road. It's now clear what Billy is searching for at the end: his brother Tommy.
Of course, there have been clues throughout the series so far that Teen is secretly Billy. Firstly, when Teen attempts to open up about who he is in episode 2, his lips curiously seal up, preventing him from doing so. We later learn in episode 3 that this is a 'sigil', essentially a spell that has put on Teen so no one can find out who he really is, hiding him from witches...
What we did know for certain is that he has a dead mother and is walking the Witches' Road in search of "power" – well, that's what he tells Agatha anyways. "Studying only gets you so far," he whispered, solemnly. All seemed to provide evidence to the theory that he Teen is indeed Billy, which would make sense given that this is a WandaVision spin-off, and ties the two show together all while providing an emotional punch.
What's interesting, though, is that Billy was imaginary in WandaVision, whilst here he appears to be real, which of course leaves us with many questions. How is he real? We'll have to wait until episode 7 to find out more about Billy, and where his path will lead him.
Who else could Teen have been?
Prior to the reveal, there were other theories surrounding Teen's identity – with some fans convinced he wasn't Billy. One other possible answer was that he might have been Agatha's son Nicholas Scratch, who's hinted at in episode 1 when Agatha's alter-ego "Agnes" wanders into his room after a long day at work (if you keep your eyes peeled, you'll see certificates and things baring his name).
In episode 3, titled 'Through Many Miles of Tricks and Trials', we received a further tease that Teen might be Nick. The coven share stories about what happened to Agatha's son, saying that they heard he was traded in for the Book of the Damned, or as MCU lovers know it: the Darkhold. One of the witches says that Agatha wouldn't even recognize her own son if he turned up on her doorstep, with the camera cutting away to Teen at this moment.
WandaVision director Matt Shakman had initially planned for Agatha's pet rabbit, Señor Scratchy, a nod to Nick, to turn into a demonic figure during that show. But alas, it never came to pass. It was therefore thought that maybe the Agatha All Along team had been encouraged to explore this here, potentially via Teen who could be Nicholas in disguise?
However, the theory seemed to be quashed in 'If I Can't Reach You, Let My Song Teach You', when Aubrey Plaza's Rio Vidal tells Agatha at the end of episode 4: "That boy isn't yours." She could have been lying, but at that point we didn't really see why she would be, especially when you consider how beat up she seems to be over hurting Agatha in the past. Elsewhere, too, there's a moment when Teen asks Agatha what really happened to her son, which suggested he wasn't Nick – or at the very least, didn't know he was.
Then, of course, there was the Mephisto of it all. Yes, I'm sorry, we are bringing up Mephisto again... though the show did it itself first. While many fans were disappointed that he didn't emerge in WandaVision after spending weeks theorizing that he would show up, maybe now was the villain's time to shine! It would certainly be fun for Agatha All Along to involve Mephisto following numerous red herrings in WandaVision, so there was (and maybe still is?) the potential for Teen/Billy to be secretly one of the devil's minions.
Whenever Teen tries to talk about himself, a cursive 'M' looks to appear across his mouth, silencing him. Could that be a sign that Mephisto is involved somehow?
Talking of which, there was also the idea that Teen is actually both Wanda and Agatha's son. But how does that work? Well, the speculation is that Nicholas was sold to Mephisto in exchange for the Darkhold, and was then born again as Wanda's son after the the Book of the Damned was destroyed.
Those were just some of the major theories and of course, though we seemingly know Teen's identity now, maybe another twist in the tale is incoming...
