Neutron said "No, The timestream it should of all changed, all at once...." meaning that when Bart went back in time, the moment he reached the past all the thing he would have done until the point when he went to Neutron's exact time would have been the past so it would have all happened, so everything he did is the past for him, so he failed and did not do everything he need to do.

So in this case, due to what Neutron has told us and what has changed in the future, the timestream is one where everything in the past affects the future all at once, not one in which the future changes as we see it. So Bart cant change the future anymore.

I still believe there is hope though. I believe what Bart has done has changed the world enough for one more person to live, so that peson may also go back in time and it will change the future. Whether it is a Legioner, a Hero, or a Villain, I am not sure, but someone will probably come from the future.

If I am wrong you can rub it in my face, but I don't think I am because of what I have seen, and because of what I understand of the timestream. So those are my thoughts. Bye.
