Warning: This article contains spoilers for Agatha All Along episode 3, “Through Many Miles of Tricks and Trials”
While the identity of Joe Locke’sMCUcharacter remains a huge mystery, one line inAgatha All Alongepisode 3 might have provided the perfect answer to who “Teen” really is. First seen breaking into Agnes O’Connor’s house during Agatha Harkness' true crime-esque,Mare of Easttown-style delusion, Joe Locke’s “Teen” has gone on to become a pivotal member ofAgatha All Along’spowerful cast of witches. Even so, his true identity still hasn’t been revealed, as a mysterious sigil has been placed on “Teen.”

First seen inAgatha All Alongepisode 2, “Circle Sewn with Fate/Unlock Thy Hidden Gate,““Teen’s” sigil not only censors his real name, but also silences his voice when he reveals important and personal information. This isn’t the most accurate spell, however, as certain pieces of information have slipped through the cracks. While “Teen’s” true identity is a mystery, there’s another question about who actually placed the sigil onJoe Locke’s new MCU character, butAgatha All Alongepisode 3, “Through Many Miles of Tricks and Trials,” might have already teased an answer.

Ever since Joe Locke was confirmed to have joined the cast ofAgatha All Along, the most prevailing theory concerning his character’s identity has suggested he could be theMCU’s Billy Kaplan, a.k.a. Wiccan. Introduced to Marvel Comics in 2005’sYoung Avengers #1, Billy Kaplan is the reincarnated version of Billy Maximoff, one of the sons of the Scarlet Witch.Julian Hilliard portrayed ten-year-old Billy Maximoff inWandaVisionandDoctor Strange in the Multiverse of Madness, but may have been replaced by Joe Locke forAgatha All Alongand beyond.

Joe Locke (Unconfirmed)
While this theory is yet to be confirmed, and some have suggested otherwise, with Joe Locke possibly even playingAgatha Harkness' own son,Locke as Billy Kaplan would explain why Wanda Maximoff would place a sigil on him. The Scarlet Witch would surely want to protect the identity of her reincarnated son, especially from the likes of Agatha Harkness. Wanda’s Glamor character used magic as a spectacle to wow the residents of Westview, and the same could have occurred for “Teen’s” sigil inAgatha All Along, with the clumsy magic hiding her son from some powerful and possibly dangerous witches.
