If those things have no effect, they why did it matter so much to go ultra stealth and try not to disrupt anything and return things to the exact moment they were taken. I know the discussion you were talking about, but there is also the discussion banner had with Strange’s mentor who explained alternate timelines could be spun that may not affect the current continuity, but could spawn other “flash points” for lack of a better term. I guess I may need to watch it again to see if that is what she was actually saying.
