Avengers: Endgame was a cinematic marvel, no pun intended, and while it delivered an epic conclusion to the Infinity Saga, it left us with a lot of questions afterwards.
The following MCU films and shows haven’t helped either as all the talk of alternate timelines and multiversal incursions have made the events of Avengers: Endgame feel a little less significant, like when Loki found a drawer of useless Infinity Stones in his spin-off series.
Avengers: Endgame’s biggest mystery though is what Captain America did after travelling back to the past, and whether that’ll have implications in the next Avengers films.
One Hell of a Delivery Man
At the end of the film, the Infinity Stones used to bring back the half of the universe Thanos erased needed to be returned to their own times. The Ancient One explained to Bruce that not returning them would create branching timelines, something confirmed in the Loki spin-off series.
So off Steve went to return the stones, though how he put them back in place remains a mystery, as some of them would be incredibly difficult to put back without raising more alarms.

One in particular that has fans puzzled is the Soul Stone, which Natasha Romanov bravely sacrificed herself for to retrieve.
The stone was also guarded by the Red Skull, so we were cheated out of a reunion between the two sworn enemies.

Because of the mystical nature of the stone though, it’s hard to understand how it could even be returned, as a sacrifice is what brings it into existence in the first place.

Marvel fans have their theories, with some believing Steve simply chucked it somewhere on Vormir as that timeline’s Gamora was one of the only people to know its location, taking the knowledge with her when she stayed in the current timeline.
This raises a bunch of other questions. Gamora leaving her original time when she did means she never joined the Guardians Of The Galaxy, so did Ronin seek out the Power Stone and use it to conquer the universe? Thanos was also killed off at the end of Avengers: Endgame, so what implications did that have for the timeline? To say the Avengers were trying to leave time untouched by their actions, they seemed to cause a lot of changes.
The theory is this will all be explained in Avengers: Doomsday, with Doom and his universe potentially facing extinction from the multiversal mess which prompts Doom to start his takeover/killing spree.
