At the end of Avengers: Endgame, Captain America is given the job to go back in time and restore the Stones to where they stole them originally. The question: what exactly happened?
Did he plan on restoring them to right after they were stolen to make it as if they were never taken, or before? And either way, according to their time travel rules -- changing the past doesn't change the future, only create a new alternate universe. So how could they possibly travel back into that same alternate universe, if every time a new alternate reality is created?
