When Thanos uses the Time Stone to reverse time in order to get the Mind Stone from Vision, the Scarlet Witch should have still been standing in the same spot and would have been firing her energy blast into the Mind Stone.
So, why is it that she is still laying on the ground behind Thanos after he finishes reversing time and is about to take the Mind Stone from Vision?
Technically, after Thanos had reversed time, he should have immediately been hit in the back by Scarlet Witch's energy blast because he had walked over and had put himself in the space between her and Vision before he started the time reversal process.
