"Bob learns a bit about paradoxes and finds he doesn't care."
In the future, Bob is stuck with Zero and Mega Man X. X freaks out, signaling a Level 10 Maverick Alert. Proto Man (still Prometheus) also freaks out, running into the bathroom, but he was merely avoiding a paradox. Bob finds out all he has to do is use his blaster until he finds an alternate universe where the inhabitants could help him with time travel.
As it turns out, Proto Man was messing with him about paradoxes.
In the present, everyone is getting ready for the party...
