Ok. So, they SAID they cut all the branches off and reverted to one timeline but that's impossible. I think we'll see the effect of this through Phase 4 and on.
- Loki escaped custody and took the Tesseract with him. He never made it back to Asgard. This alters the events of Dark World and forward. It also means that Thanos is coming for him. He stole the Tesseract in 2012 and Thanks didn't go to the future till 2014, so Thanos is alive in this timeline.
Something with this will tie into the Disney+ Loki series, guaranteed.
- Captain America going back to live out his life completely changes everything. He gets with Peggy, which means she never married her other husband and this will wipe Sharon out of existence in this timeline. Also, there are two Caps in this timeline now. Present day Cap and Frozen Cap. So, what happens when 2012 hits and Cap is unfrozen? What happens when he goes to look for Peggy only to find out he's already married to her?
Also, Peggy Carter is a founder of SHIELD. Did that happen? If it did, which I'm sure it did, I don't see her and Steve doing nothing for 70 years but dancing. I bet anything we see Chris Evans return at some point and we get a movie or a show in this timeline. You'd have Cap, Carter, Hank Pym, Janet Van Dyne and Howard Stark all around.
- There is still a 5 year gap unaccounted for between the snap and undoing the snap. We're gonna need a lot of that filled in at some point since the MCU didn't reset to 2018, it's still 2023 in the MCU. What happened in those 5 years that will play into Phase 4? I bet anything this will also play into Phase and on. It's gonna be how we see Black Widow again, I'm sure.
- Since 2014 Thanos was killed, he doesn't exist in that timeline so the snap never happens in that timeline ultimately. Also, since Nebula and Gamora won't be going after Quill to get the Power Stone, the events of both Guardians movies don't happen. So, what did happen in this timeline?
I assume the events on Earth play out exactly the same up until Bruce was supposed to crash into Strange's house. Asgard is probably still destroyed but their ship never gets attacked so Loki and Heimdall are still alive.
Could Black Widow be brought over from the universe that wasn't snapped? What else will happen now that they have a way to time travel and fuck shit up more?
My guess is because of this mess it's going to bring in Kang the Conquerer to deal with all these realities that have splintered off and he's going to be trying to reduce everything down to one time line again. We could see a Phase 4/5/6 that deals with various universes that will intersect at various points as Kang bounces around and it still culminate in all the universes coming together to fight Kang which would result in his defeat but him also accomplishing his goal and only one universe remains at the end with a hodge podge of characters from each universe surviving. This would give birth to yet another new beginning of the MCU in 2028. ?
