Rift Vegeta: I have never beaten him before, I have only seen a taste of his power.

30 Vegeta: Beating him the same time is impossible. He can only grow stronger at this rate, unless one of his mind screws or whatever back-fires on him. The chance of that happening is zero to none.

Rift Vegeta: And I doubt mind control could work. He probably has too small of a mind to work with.

30 Vegeta: *Smirks* It's a one-shot, you will die if this fails, possibility, but it's not even worth it.
