While the true identity of Joe Locke’s “Teen” in Agatha All Along remains a mystery, a wild new MCU theory might have provided the most unexpected suggestion. Joe Locke made his MCU debut as a fan and fast friend to Kathryn Hahn’s Agatha Harkness, but it’s still unclear who the Heartstopper star is actually playing in the MCU. Dubbed “Teen” by Agatha, because he’s 16-years-old, he has joined the new Westview coven on their journey down the Witches’ Road, but each new episode of Agatha All Along raises new questions.
