A little elaboration on the hypothetical I gave:
There would be a very good likelihood that the key would simply be dragged along with the ball, while time would flow normally for the key.
Anyway, I see your point, and I generally agree with them.
I noticed a spelling inconsistency in the description, specifically the first time the protagonist is mentioned
(I’m just typing this in passing, not going to read as the genre isn’t for me. I’m just hoping this helps)
If one could freely manipulate time, wouldn’t they logically be able to cherry pick what gets affected by what alteration they make to time?
Like making a ball go backwards in a thrown trajectory, but having a key that’s inside the ball remain unaffected?
