I loved all the callbacks to the previous movies too. So the Captain Marvel mid credits scene wasn't in Endgame after all. Where does it fit in? It seems to be the first encounter between the Avengers and Carol. I have to watch Endgame again, but I guess it goes sometime before Tony is recording his first message for Pepper. So the Avengers on Earth are examining Fury's pager, they remember that some of the team might still be in space and send Carol to look for them?
And it looks like everything in our timeline is confirmed, which is great. Teams of heroes all travel from 2023 to different times to retrieve the Infinity Stones.
2012- Timeline of The Avengers. Tony, Steve, Scott, Bruce arrive in 2012 New York to get the Space, Time and Mind Stones. Steve successfully gets the Mind Stone (Scepter) by whispering "Hail Hydra" to known (to him) secret Hydra agent Sitwell. Bruce gets the Time Stone inside of the Agamotto necklace by telling the Ancient One that Doctor Strange willingly gave it to Thanos. She mentions that Doctor Strange won't be a sorcerer for another five years (2017). Steve and Scott fail (because of 2012 Hulk of course) to get the Space Stone (Tesseract) and Steve and Tony decide to try again in 1970.
2013- Timeline of Thor: The Dark World. Thor and Rocket travel to 2013 Asgard to extract the Aether (Reality Stone) from Jane Foster. Cool to see Natalie Portman again, even if just deleted "Dark World" footage, though I guess she did record new voice work.
2014- Timeline of Guardians of the Galaxy. Rhodey, Nebula, Clint and Natasha travel to 2014 Morag. Rhodey and Nebula get the Power Stone (Orb) using a tool taken from a knocked-out Peter Quill. Clint and Natasha travel to Vormir to get the Soul Stone. They're four years early, but it, and the Red Skull have presumably been there since the 1940s. Now I was just thinking about this, since Steve returned the Soul Stone, does that mean that Natasha can come back? I mean if the Soul Stone was "never taken", doesn't that mean that Natasha was "never sacrificed"? Of course 2014 Nebula, Gamora, Thanos and his minions were also transported to the "present day". Gamora will eventually "become" her present day self, but the others were of course killed.
Speaking of 1970, we now have a better idea of the foundation of S.H.I.E.L.D. It was founded no later than 1970, and we see that Howard Stark, Hank Pym and Peggy Carter were all working together (or at least in the same building) at this time, as alluded to in Ant-Man's 1989 prologue. Was any mention made of Project Pegasus? Would have been interesting to see Mar-Vell (aka Wendy Lawson) here too, but I assume she didn't come around for another 10-15 years.
Anyway, I can't wait to see the movie a second time. Pretty upset that I already knew that Tony and Natasha died, Thor got fat and Cap would wield the hammer, all due to stupid Quora questions that I didn't even read, other than the "headlines/ questions" while browsing unrelated stuff. RIP Tony Stark and sort of Steve Rogers. I'm betting Vision and Widow will be back.
I was assuming at some point they'd go back to 2018/19, but I guess we're stuck in 2023 for now. As some of you have mentioned, this only makes sense if Peter Parker's entire school was "snapped".
Loved seeing Jarvis (the butler), interacting with the "other" Howard Stark. (Do we assume that Dominic Cooper is ONLY 1940's Stark, and John Slatery is 1970-1991 Stark, or will Slatery still be Stark if we see him in the 40s again), Sitwell, Alexander Pierce, the kid from Iron Man 3, "grown up" Cassie (though sort of upset she didn't "do" anything), Pepper as Iron Girl (Rescue I guess? I don't read comics, I know.. I know..) and especially Jane Foster.
