Hi, yes, hello! It's another week, and that means another incredible episode of Agatha All Along. Episode 6 — titled "Familiar by Thy Side" and directed by Gandja Monteiro and written by Jason Rostovsky — had us go back in time to see William Kaplan's (Joe Locke) origins and how he ultimately became Billy Maximoff.

SPOILER ALERT! This post contains details from the sixth episode of Marvel Studios’ Agatha All Along. Agatha All Along viewers have a lot more answers than they did two weeks ago, but there’s still plenty left to come as Agatha (Kathryn Hahn) and Billy (Joe Locke) continue down the Witches Road together.
