WandaVision

So what are the odds that whatever was going on in the basement leads to the Nexus of All Realities?

Odds of (Giant Size) Man-Thing showing up currently at .00000002%, but a man can dream.

If you watch again, the aspect ratio changed as Wanda went into the basement, signifying that we aren't in Westview anymore as it does when we check in on SWORD, so...maybe not as far-off as you might think?
