Couple more questions.....
What happened to Gamora during/after the final battle? The last I remember of her, she was in the scene where Nebula shot Nebula, then I don't remember seeing her again (particularly not during the funeral scene).
Next: how is Falcon able to wield Captain America's sword and effectively inherit the Captain America title? From what I gathered, Falcon always was sort of a weak MCU character, with no real physical enhancements and strictly reliant on his mech wings to provide aerial support. Steve Rogers was super-human in strength, resilience etc. and could withstand a shit ton of abuse even without his shield. I also thought that the shield required superhuman strength to wield effectively. Really not sure how Falcon getting the shield makes sense and how he will be able to wield it well.
Why did anyone need to inherit the shield? It could have easily and fittingly been retired with Captain America.
EDIT: another thought ; wasn't his shield shattered by Thanos in the final battle? Did he get another one? WTH?
Gamora: She has a scene with Star Lord and then she flees.
Falcon: Watch the Disney+ show to find out. But if you must know - being Captain America was never about being super strong, the first movie in his trilogy reinforced this multiple times. Sam can wield the shield fine, can fly and has tech gadgets like Redwing. He will be just fine.
Shield: Captain America is becoming a mantle and Steve wanted someone to protect the world in his stead since he knew he'd come back old, if he came back at all. Sam is the closest to him morally and it makes complete sense to pass the mantle to him.
Shattered Shield: Steve went to an alternate timeline to live out his life with Peggy, one in which the shield wasn't shattered yet. Even if you assume that shield eventually shattered, Steve could alter things just by his mere presence and maybe Howard made multiple, or T'challa made him one. The main point is there are a lot of sources for a new shield.
It's the biggest hint that he went to a different timeline.
