Well as far as I know is, the start-point Vegeta came here, Nightmare followed afterwards, and caught that Vegeta mouthing off, was "insulted" by a few stupid things that he said, and killed him. At some point a Kakarot came and tried to stop Nightmare, but failed. Luckily Kakarot wasn't too far away, so I was able to catch up. We were literally one wish away from having a doubled universe! >< WHY!? MY JOB IS HARD ENOUGH AS IT IS!!
