Spoilers for the season finale of WandaVision follow.
So, Mephisto wasn't the one pulling the strings in Westview after all. Right from the start, fans assumed the demonic Marvel Comics villain would be revealed as WandaVision's big bad, and the show even dropped a few hints that this would be the case. Add in some "leaked" merchandise photos, and many viewers were convinced that we'd see the character in the recent series finale.
Of course, that didn't end up happening ("it was Agatha all along"), and from the sounds of things, Mephisto never factored in to any early plans for the story.
During an interview with Deadline, EP and head writer Jac Schaeffer revealed that she simply didn't feel that the show "needed a big bad."
"I mean, the big bad is grief, you know, and that’s the story that we were telling, and then we got a bonus baddie in the form of Agatha Harkness who ended up facilitating Wanda’s therapy, so yeah, I think we feel pretty good about that."
Schaeffer was also asked why Doctor Strange never appeared to set-up Wanda's role In The Multiverse of Madness, and based on her response, it sounds like that might have been something that was considered at one time.
"I heart Doctor Strange just like anybody. Yeah, it’s one of those things, that’s how the chips fell, that’s how the cookie crumbled, is what I will say, but I look forward to seeing him on screen with Wanda in Doctor Strange 2."
