Here's why Vision is the biggest threat to Scarlet Witch's fake reality in WandaVision. Marvel Studios' star-crossed lovers reunite after the events of the Infinity Saga and head on to live a blissful suburbia life in Westview. The problem is, chances are that this ideal world that they're in isn't real, with Wanda potentially using her reality-warping abilities to create it herself.

Amidst the lighthearted jokes and sitcom references, there's a bigger and darker narrative unfolding in WandaVision as strongly suggested by a series of inexplicable occurrences in Westview. The last episode made it clear that  Wanda and Vision's fantasy world is taking place in a pocket reality protected by a mystical barrier after Monica Rambeau, aka Geraldine, was forced out of it when she mentioned Ultron's involvement in the death of Pietro Maximoff. It wasn't shown on screen, but the general idea is that Scarlet Witch herself kicked her out of the bubble. This wasn't the first time Wanda did this to preserve the illusion of a perfect life with Vision; she's also rewound time every single time something threatened to reveal what's really happening in Westview.

There are a couple of factors that are currently threatening Wanda's fake reality in WandaVision, and if there's anything that the past few episodes proved, it's that she's willing to go to great lengths to protect it. Unfortunately for her, her biggest problem is Vision himself. While the synthezoid is more than willing to live the simple life in Westview with her, it's also clear that he's not entirely aware of what's happening around him; he might not even know that he has technically died in Avengers: Infinity War. And the thing about Vision is, he's still essentially a robot; he's data-driven and pragmatic. As more bizarre things happen around him, he will be more curious to get to the bottom of these mysteries, forcing Wanda to work doubly hard in keeping up with the charade.

Twice in WandaVision now, Vision almost found out about what's really happening in Westview. In episode 2, the mysterious beekeeper who's more likely a SWORD agent infiltrated the town and in the subsequent outing, he grew doubtful of the quick progression of his wife's pregnancy; in both instances, Wanda was able to cover things up by turning back time, manipulating the subsequent events and distracting Vision from his dangerous thoughts. However, Wanda wasn't with him when he had that odd encounter with Herb and Agnes who firmly planted the idea in his head that something's not right in Westview, preventing her from doing the same trick she's done to him since they first spotted the beekeeper. In a future episode, Agnes will also straightforwardly tell him that he's supposed to be dead, further making him suspicious.

While Wanda might not have any issues harming others to preserve this fantasy world as evidenced by what she did to Geraldine, things are going to be tricky once Vision poses serious problems for her. Obviously, she doesn't want to hurt him and once he starts digging deeper into the mystery in WandaVision, it would be difficult to dissuade him from it. That said, if there's anyone who can convince Scarlet Witch to give up this fake world and finally let him go, that's also going to be Vision.
