A Marvel fan is urging people to re-watch a WandaVision scene following the final episode of Loki.
Could this exact moment be when Sylvie kills He Who Remains, causing characters in the Marvel Cinematic Universe (MCU) to become aware of the Multiverse?
However, when Loki returns, he discovers he’s in the wrong timeline and that Sylvie, as He Who Remains warned, has caused another Multiversal war.
While the theory is unconfirmed, it is fun watching the WandaVision moment back while keeping the events of Loki in mind.
