Piccolo and Vegeta in “Unfinished Business”

Piccolo

[about Frieza] I see. King Kai thinks he's unbeatable. We'll find out.

Vegeta

You're right. We will. But who are you? Just another weak Namekian? Wait, I recognize you. You're the one we destroyed so easily on Earth. I can't believe these fools wasted their wishes bringing you back to life.

Piccolo

Do me a favor. Just keep your big mouth shut. Then, after we beat Frieza, it'll be you and me...head to head.

Vegeta

Yeah...like that's actually going to happen. Heh heh heh. Ha. I guess some people just aren't satisfied with dying only once, are they?
