Ah, better. Still not sure it resolves anything about how the original Banner would have become Hulk in the first place once Hulk Squared happens. Shouldn't it negate the original Hulk transformation? But it's best not to think too hard about time travel plots, unless it's in the hands of a very nuanced writer. Even good time travel stories often have gaping holes.No worries. I think I'm good now.
True Time Travel is paradoxical if done in the way we want (ie. past events in our lives or "our realities" altered, with their effects cascading over us - not quitting that job in the city, not pulling back from the kiss with that girl ...), because the need that causes us to act is the very thing that gets erased by our actions in the past ...
As far as I understand it, time in the MU works by branching out, each time you make an alteration, another time-line pops into being, branching off from that decision point.
This makes sense of things like "Future Imperfect" and "The End", which all "happen" but somehow the knowledge of one or the reality of the other do not seem to contradict or interfere with the present that Marvel 616 exists within.
Yet they couldn't resits the Marty McFly thing of having your present actions in the past cascade onto you - in your current past - making Banner forget crucial people in his life or pulling Hulk persona from different points in his time line ...
