The biggest assumption fans have made about WandaVision is that it will begin exploring the MCU multiverse. This is largely because the show leads directly into the next Doctor Strange flick, titled Doctor Strange in the Multiverse of Madness, which will obviously tackle exactly that. 

But it's odd that Doctor Strange's schedule will clear up for that, since last we heard he was unavailable to help in world-crashing events.

In Spider-Man: Far From Home, Peter Parker is recruited by Nick Fury to help stop the Earth-shattering Elementals from destroying the world. Surprised that he's the man for the job, Peter specifically asked Nick Fury why they needed Spider-Man's help when they could ask someone like Doctor Strange. Maria Hill then quickly chimed in that the Sorcerer Supreme is currently "unavailable" to help.

Fans know that Far From Home takes place about nine months after the events of Avengers: Endgame, so something else must have come up after the big battle with Thanos to keep Doctor Strange from helping with these rampaging Elementals.

But what's recently been revealed in the latest episode of WandaVision is that the Disney+ series picks up just three weeks after Endgame, meaning the events of the show begin way before Spider-Man: Far From Home does. 

So now that fans know where the first MCU Disney+ series sits on the timeline, it may actually be because of WandaVision that Doctor Strange is conveniently occupied when Spider-Man has to handle the full force of Mysterio alone.

Beck mentions in Far From Home that a door has opened for a new hero to step in now that Tony Stark is gone.

Stark was clearly a very personal issue to Quentin Beck and his crew in Far From Home, and his departure from the MCU surely did free up some space on the superhero roster. 

But Iron Man shouldn't be the only one standing in Beck's way if he were to wreak havoc on Earth like he did. 

In fact, it's pretty much in the job description for the Sorcerer Supreme to handle the threats that presented themselves in Far From Home. 

So what was so important to Doctor Strange that he wasn't able to step away to deal with Mysterio?

If WandaVision leads directly into Doctor Strange in the Multiverse of Madness, then it's possible that Doctor Strange already knows about the events of WandaVision before the series ends. After all, why wouldn't he? 

Because of this, Strange may intervene in the events in Westview before the show's last episode. If this is the case and it's serious enough for Doctor Strange to get involved, then who can tell how long it will take for the Sorcerer Supreme to fix Wanda's mess? 

Perhaps Doctor Strange isn't available in Spider-Man: Far From Home because he is still dealing with the consequences and further implications of the events in WandaVision

POST-CREDITS DECEPTION

Far From Home included a crazy scene right as the credits began to roll where Mysterio revealed Spider-Man's identity to the world, making it one of the best post-credits scenes and cliffhangers in MCU history. 

Revealing Spidey's identity to the world has never been done in a Spider-Man flick before. It was easily one of the biggest developments in Far From Home and it will surely have huge implications for future Spider-Man endeavors in the MCU.

So why was it put in the middle of the credits? Maybe this big moment was also meant to downplay the second scene that accompanied it. 

KEEPING HUSH ABOUT THE MULTIVERSE 

The final scene in Far From Home reveals to audiences that Nick Fury and Maria Hill were actually Talos and Soren — two Skrulls that bonded with the real Nick Fury in Captain Marvel

The scene depicts a conversation between the two Skrulls as they discuss how they could have handled the events of Far From Home better. After a heated debate, Soren convinced Talos to update Nick Fury on what's been going on. 

While Talos is explaining to Fury how difficult this particular mission was for him, he took time to mention how Peter asked where the rest of the Avengers were and why they were unable to help.

Talos then says that he "doesn't know what to say to that," implying that he's not supposed to divulge that information to the young hero. 

What's important to remember is how little Peter actually knows about what's going on in the world. When Peter meets Quentin Beck, he's shocked to hear about the implications of a multiverse. But if WandaVision has already taken place and it's created a rift in the multiverse itself, then this interaction actually provides some great insight as to where the MCU currently is as a whole in Far From Home

If Peter wasn't aware of the actual possibility of the multiverse, then that could mean the events of WandaVision are not yet public knowledge. But Talos' acceptance of Beck's multiverse cover story shows that there is reason to believe him, alluding to possible recent events involving it. 

If Wanda does tear a hole in the MCU's reality in WandaVision and she creates a multiverse of madness that Doctor Strange will have to deal with, then this would be a worthy excuse for leaving Spidey as the only one left to help with the Elementals.

There's a good chance that Doctor Strange is dealing with the aftermath of WandaVision, and Talos isn't allowed to tell anyone about it. 

RIGHT PLACE AT THE RIGHT TIME

Mysterio claimed that his fake backstory about being from the multiverse is perfect, and that it's 100% what the world would believe right now. Why is that? 

It's not like Quentin Beck was a ghost before he popped up in Far From Home. He was a former Stark employee gone rogue. Yet somehow, Mysterio and his secret team were able to operate directly alongside SHIELD and fool them at every turn until Spider-Man came along.

Perhaps the events of WandaVision have already had horrible implications, and Beck found out about it. His crew clearly has exceptional connections all over the world, so if he was able to stay one step ahead of SHIELD and Spider-Man for as long as he did, then he likely had someone on the inside feeding him intel that would help their efforts of fooling the world. 

Talos may be inclined to trust Beck's story of how he came from the multiverse because of possible recent events involving it. A convincing reason why Talos would believe Beck — and even sympathize with the gravity of his fabricated Armageddon — is because Talos is aware of just how terribly sensitive the multiverse is at that time, thanks to the events of WandaVision.
