When Agatha Harkness moved in next door, she brainwashed Ralph, tricked him into thinking he was Wanda’s brother Pietro, and used him to spy on her.
Some will probably get settled in future Marvel movies like Doctor Strange in the Multiverse of Madness.
As it turns out, Ralph really was the dude who lived next door to Vision and Wanda’s home.
All season, for example, fans waited and waited to find out the true identity of “Ralph,” the oft-mentioned, never-seen husband of Agnes (AKA Kathyrn Hahn’s Agatha Harkness).
