So for those of you who didn't get a chance to check out our coverage on it yesterday, WandaVision and soon-to-be Agatha: House of Harkness star Kathryn Hahn stopped by Drew Barrymore's talk show where the topic turned to the Disney+ & Marvel Studios' spinoff series. And as expected, the topic turned to whether or not Mephisto would be making an appearance (a demonic presence that fans were hoping to see in WandaVision). "I keep hearing that. I have no idea! That was like a big thing during 'WandaVision' but I have no idea. Who knows? Probably anything is probably possible, but I have never heard anything definitive about that at all."
But that's when things got our dumpster fires of random speculation raging because when asked who she would cast in the role, Hahn took a big and rather obvious drink break before admitting that she was about to deflect from the question: "Immediately you think of a woman who is loud, who is mysterious, who is dangerous because she's complicated and she's misunderstood. And all that stuff is a real turn-on to me as a performer in terms of digging into this person a little bit more. Very excited." And that's when we came up with the theory that not only is Mephisto going to appear but also that an actor has been cast or is close to being cast. How? Hahn's on-screen beverage habit.
Because it reminds us a whole lot of how Hahn handled the "Agatha Harkness" question when it was posed to her by late-night host Jimmy Kimmel back in February. Appearing on Jimmy Kimmel Live to support the series, Hahn was asked about the online theory that Agnes was actually Agatha Harkness. Starting at the 3:00 mark, Kimmel mentions similarities in appearance as well as the oval pendant. Hahn's response? She comes back with a drink that distracts Kimmel until the conversation turns to Hahn buying her very first computer and not being on social media. Once again, smoothly gave an answer to a question that wasn't asked while rolling on with the interview like nothing ever happened (and we know how that turned out). Very similar to what happened on Barrymore's show. Could we be wrong? Oh, absolutely! There's an excellent chance that this is more speculation than fact. But the similarities are worth having a little fun with, and it would definitely explain why Hahn could name anyone. Would you want to know that your co-star would've preferred someone else in the role you got?
