2. The Spider-Verse Has Already Begun
One of the biggest reveals from episode 4 was the show's timeline in regards to the wider universe. The first scene hauntingly showed Monica's re-emergence after Hulk snapped all the blipped beings back into existence before she returned to work at SWORD just three weeks later.
So this puts WandaVision just three weeks after the events of Avengers: Endgame, and therefore roughly just over seven months before Spider-Man: Far From Home. This may not seem important, as there is just about zero connection between WandaVision and Spidey's second outing, but what if there is?
The mid-credit scene at the end of Far From Home showed the shocking return of JK Simmons' J. Jonah Jameson, something that raised questions among fans regarding the connection between the MCU and Sam Raimi's Spider-Man trilogy. These questions could be answered by Wanda and the Multiverse of Madness, and it could be that the two versions of the character in both franchises are actually one in the same.
Since there is seven months between Wanda taking over Westview and Jameson outing Spider-Man's true identity, there is plenty of time for the former to roam across the multiverse and somehow, likely inadvertently, bring the latter from Tobey Maguire's universe into Tom Holland's. This could mean that the Spider-Verse reportedly coming to the MCU in the third movie of the trilogy has already begun with the Daily Bugle reporter.
