(same anon) Also, on the Bloodlines page there is an unanswered question: "Why did the future not change when Impulse fulfilled his mission?" The future did change. Neutron's prison clothes were changed to normal clothes and he lost the inhibitor collar because in the future he was no longer a supervillian after Bart gave him the cure (and saved Flash). And it is implied that those things aren't all that he was sent back to fix because Neutron also says "and that's only the beginning" after he reminds impulse of those specific tasks. Therefore, we have yet to see what the rest of his mission is and being as the future still seemed apocolyptic, it appears he doesn't "fulfill" it.
