Marvel 'Agatha All Along' fans may have already sussed out Joe Locke's mystery character
Played by "Heartstopper’s" Joe Locke, this goth teen breaks Agatha (Kathryn Hahn) free from Wanda's spell and helps her form a new coven of witches (Debra Jo Rupp, Sasheer Zamata, Ali Ahn and Patti LuPone) so they can face the trials of the legendary Witches' Road and restore her powers.
