Be aware: the whole question is basically a major spoiler!
In the last arc of Doctor Strange (2016), Strange and Mordo
arrived in an already destroyed Hongkong. Strange then used the magic of his infinity stone to rewind time, presumingly aiming to get to the point, where everything was okay.
But while doing this, Kaecilius managed to break the effect on him. How was he able to do this? How did he get to know, that something on a different timeline was affecting him AND breaking the effect?
I mean, Strange used
an Infinity Stone!
How comes, that some above-average mage was able to break
the effect of one of the six strongest forces in the universe?
