Joe Locke's Agatha All Along Character Identity Revealed

Spoiler alert: This article contains information from “Agatha All Along“ Episode 5, “Darkest Hour, Wake Thy Power.”

The ending of Agatha All Along episode 5 has given clear clues about Teen's true identity.

In the heated moments after Agatha Harkness (Kathryn Hahn) absorbs Alice's (Ali Ahn) powers, Teen, played by Joe Locke, confronts her on Witch Street for killing her second coven member and asks her if it “To kill” means to be a witch people who serve your own agenda?”

After looking at him for a split second, Agatha giggles and says, “Are you sure?” You’re so much like your mother.”

Then Teen becomes angry and viewers see his true powers for the first time.

Teen uses mind control on Lilia (Patti LuPone) and Jen (Sasheer Zamata) to push Agatha into the sinking mud before throwing them both into the mud as well.

The final shot of the episode shows a blue crown appearing over Teen's head, looking very similar to Wanda Maximoff (Elizabeth Olsen), also known as Scarlett Witch.

Audiences have even pointed out that the playing of Billie Eillish's “You Should See Me in a Crown” as the outro suggests that Teen is Billy, one of Wanda's sons.

Since costumes change with each house the coven enters, Teen's costume bore a resemblance to Billy Maximoff in the Halloween episode of Disney+'s “WandaVision.”

“It took 16 years for the MCU to give us queer ICON WICCAN, but now he's officially here!! 😫🙌🏾🔥When Agatha said, “You’re so much like your mother,” I screamed Wanda’s name! one of the greatest MCU moments of all time! #AgathaAllAlong #AgathaAllAlongBash,” one person wrote on X, previously Twitter.

“'You are so much like your mother' AND THEN THE CROWN I WILL DIE #AgathaAllAlong,” another person wrote.

Another social media user commented: “This will go down in MCU HISTORY as one of the craziest reveals EVER like I've never been so damn gagged #AgathaAllAlong.”

Teen's identity has always been a mystery, although many fans believed Teen was Billy Maximoff even before the series' debut.

Viewers first got a glimpse of the secret after he began sharing his childhood with Agatha in Episode 2, and Agatha couldn't hear anything as Teen's voice was drowned out.

It is also noted that when another character asks Teen who he is, a seal appears on his mouth, preventing him from revealing who he is.

Previously he asked Agatha if she was the one who put the seal on him and she replied: “No. Actually, I wouldn't know. A seal also affects the witch who cast it. That's why we don't use them that often. They’re super irritating.”

She later said that sigils are destroyed “when they are no longer needed.”

Fans of the series have speculated that Teen's true identity was Nicholas Scratch, Agatha's son in Marvel Comics lore. It was revealed in the show that Agatha had traded her son for the Book of the Dead when he was a baby and had not seen him since.

This theory was debunked in Episode 5. Amid the chaos of Agatha's trial in the house, Teen asks the Ouija board who the ghost is, and the name that was written out is Nicholas Scratch, suggesting that he is no longer alive.

Agatha All Along showrunner Jac Schaeffer previously spoke to EW about the teen theories.

“It’s about how we peel back the layers,” she said. “Our job is to make the revelations exciting and satisfying. Now when I see the theories I still get a little nervous, but I have the experience of it WandaVisiona voice in my head that says, “Well, no one knows.” How.'”

We're finally at a point in the series where we understand the how.

New episodes of Marvel Studios' “Agatha All Along” air Wednesdays at 9 p.m. ET on Disney+.
