How did Thanos rewind the Infinity Stone in Vision at the end of Avengers: Infinity War? The stone is 1/6 of a Goddess and Doctor Strange can't even rewind a semi magic Book with 'Consequences'. It doesn't really make sense to me unless this will be a key plot point in Endgame.
The key is to remember the scene with the apple in the Dr. Strange movie.
If you recall, Dr. Strange uses the Time Stone to reverse and advance the age of the apple, from half eaten to uneaten to rotting.
This shows that the Time Stone can specifically target an object, which is what Thanos did to Vision.
