[#-3]

I'm thinking the Disney+ Marvel model is pretty clear at this point. Somewhere between the first 4 episodes and 50% of the series we get semi-serialized world building, that doesn't really show us the coherent grand plot of the season. Then slowly stitching the threads together.

fan theory with trailer spoilers

Spoiler!

I think episode 4 being Dark Doctor Strange is important. We are going to start to see the boundries between these worlds breakdown, as we see what happens when Dr Strange goes bad.

In the following 3 episodes we will see other stories taking place in the timelines we have already.

Party Thor is living in a World where T'Challa turned Thanos good, so Loki was never contracted by Thanos to conquer Earth and Thor never had to grow up.

Killmonger saves Tony Stark in a world Captain Cater appears at projcet project pegasus. In this world Peggy wasn't around to build SHEILD, so we have a very different military industrial complex that leaves the soldier and the weapons dealer in different places at the start of our journey.

The Dead Avengers are re-incarnated a zombies, and the newly de-iced Captain needs to take care of the zombie problem.

On Sakaar instead of the Hulk/Thor/Valkyrie team up, you get one character straight from each of these time lines, blending the story together.

And in the Finally in none of these timelines did the have the 11 Avengers our timeline required to overcome Ultron, so in infinite Ultron, all of these worlds need to team up to take down all of their Ultrons.
