In the rare case you haven't traversed Twitter in the past month, WandaVision has been the talk of the town. What's going on with the people inWestview? Why does SWORD want Vision's (Paul Bettany) body so bad? Most importantly — who's the big bad of the series? Six episodes in, the series has yet to unearth a puppetmaster behind WandaWorld, suggesting the Scarlet Witch (Elizabeth Olsen) herself is behind everything, at least as of this writing. Now, one interesting fan theory suggests Ultron could have been in front of our faces the whole time, pulling the strings all along.
