The WandaVision finale crammed a lot into just 40 minutes. So now that the dust has settled and the Hex is broken, it's worth taking a look back at some moments that didn't register the first time around. To start, we should probably talk about a specific part of Vision and White Vision's big fight and what it reveals about an earlier chapter in Wanda and Vision's story.
Warning! Spoilers ahead for WandaVision Episode 9.
While Wanda and Agatha Harkness chuck magic at each other, Vision and White Vision duke it out over Westview. Eventually, Vision uses logic to diffuse the situation, but before that can happen, his evil doppelganger comes pretty close to killing the Vision in a very familiar way.
White Vision grabs Viz right by the Mind Stone and starts to squeeze. "You must be destroyed," he says, but Vision simply uses his density-control abilities to simply phase out of danger.
If you watched Avengers: Infinity War recently, you probably recognize this moment. At the end of the movie, Thanos tries the same trick on Vision — and it works. When Thanos grabs the Mind Stone and starts pulling, Vision doesn't phase away. He barely puts up a fight at all. So what gives?
As TikTok user @potatorecipes points out, this feels like a pretty big plothole, but the truth is not quite that simple.
WandaVision vs. Avengers: Infinity War
Did the Russo Brothers drop the ball? Maybe not. Vision starts the movie by getting stabbed with an alien weapon that (temporarily?) disables his powers. Then he spends much of the film on an operating table while Shuri plays around with his brain. Finally, the love of his life kills him only for Thanos to turn back time and kill Vision himself.
That's a lot to go through. So it makes sense that Vision wasn't able to put up a fight — especially since he was still suffering from that stabbing at the beginning of the movie. In other words, Infinity War cleverly bakes this logic into its first act so by the time you get to the ending you won't see it coming.
However, the real reason Vision didn't phase away from Thanos is likely because it didn't fit with the narrative of Avengers: Infinity War. The entire point of the movie is that the Mad Titan is an unstoppable force. No one can stop him. Not the Hulk, not Iron Man, not Captain America, and not Vision.
