Well, they do say the devil's in the details.
Marvel released a new WandaVision poster earlier today to accompany the mid-season trailer, and while there didn't seem to be anything out of the ordinary about it at first glance, there might just be a very interesting Easter Egg hiding on the wallpaper in the background.
If you look closely at the pattern between Vision's neck and Agnes, it does somewhat resemble a demonic face, and some fans are convinced that it's actually supposed to represent Mephisto.
There's been speculation that Marvel's powerful sorcerer might ultimately be revealed as the show's main villain ever since the first episode, and this has only added fuel to the fire (no pun intended).
Check out a zoomed-in version of the image below (via The Direct).
Based on everything we've seen so far, it looks like Wanda herself could be responsible for the strange goings on in Westview, and may even be revealed as the villain of the piece. Of course, that doesn't mean someone - or something - else isn't pulling her strings, and that could well turn out to be Mephisto.
What do you guys think? Is there anything to this? Drop us a comment in the usual place, and be sure to tune in to Disney+ this Friday for the fifth episode of WandaVision.
