Being a quasi-sequel series to WandaVision, Marvel’s Agatha All Along was bound to pick up most of that show’s loose plot threads at one point or another, at least when it came to Agatha or Westview.

Agatha All Along brought back a certain character from WandaVision in a flashback episode that helped Joe Locke's Teen find his way to Agatha Harkness.

We all thought that was the last we would see of Ralph, but the MCU is always full of surprises. In Agatha All Along episode 6, which is titled 'Familiar by Thy Side', Peters returns for a surprise cameo as Ralph during a flashback scene that dives into Teen's life before the Witches' Road.

Agatha All Along's sixth episode brings back another WandaVision character to answer some very important questions for Teen.
