Nappa prepares to blast something at Goku. Goku blocks it easily, amazing Vegita. He attacks Nappa by coming up from behind him and hitting him over the head. "This one's for Piccolo!" He shouts. Nappa hurtles towards earth, and Goku appears beside him. He kicks Nappa into one of those convinient rock piles that everyone likes landing on. I guess it's more dramatic than bouncing on the ground. Nappa gets up, and he's very, very angry.
Back at Master Roshi's, Bulma's mad. Nothing will happen to Goku! She's sure! She slaps the crystal ball across the room, angering everyone. The witch gets into a "say-it-don't-spray-it" argument with Bulma. With some technical difficulties, they get the ball working again. Back on the field, Nappa does his biggest attack yet! But Goku survives, with a heart-felt "that was too close for comfort". They do some hand-to-hand stuff for a while, but Nappa's clearly outdone. He gives up, saying that Vegita can take it from here. Nappa wants to have some fun. So he heads for Gohan an' Crillan. Goku sees this, and does a Kao Kan attack to get in front of him. He injures Nappa very badly. While Goku explains Kao Kan to Crillan and Gohan, Vegita blasts Nappa to the next dimension.
Goku is worried about Crillan and Gohan. He tells them to go home. After several minutes of talk, good-byes, warnings and it's-safer-this-ways, Goku and Vegita leave to fight in a more deserted area, which by my standards is not possible, but anyway, they leave. Once there, Vegita tries some Darth Vader-like persuasive speech-making. Goku, like all good superheroes before him, refuses to join Vegita. They begin combat. (I'm tired of saying "they start fighting.") At first, Vegita seems to be the stronger and smarter one. Then Goku uses his Kao-Kan attack again, and gets a couple of good hits off before Vegita kicks him. The fight continues like this for the rest of the episode (about 2 or 3 minutes). What happens next? Sorry, but you won't find out from me, cuz I'll be at camp next week!
