it’s like
that question was literally answered like twice.
Their whole plan was to just basically go back, get the gems, snap, then return them like they never left.
If everything would’ve went smoothly, we would’ve never got the ending
The reason things resorted to how they did was cuz they literally failed in the past, not just once but twice
(fukked up with the tesserect, forcing them to attempt to retrieve a 2nd time, fukked up with getting the power stone, tipping off Thanos of their plans)
It those 2 things don’t occur.... this movie basically is over in 15 mins and only Scarlet dies.
Cuz with Hulk, there’s no need for Tony to sacrifice himself
Also Cap doesnt to back to be with Peggy so he’s still young and in this timeline which also means no Falcon and WS
check me if I’m wrong or lying
