The episode starts off with the Androids flying off to find Goku. Krillin watches in depression as he knows if the Androids find Goku they will kill him. Krillin then goes and gives everyone a senzu bean. Afterwards everyone sadly says how badly they were beaten. Vegeta madly flies off after his defeat. Future Trunks was ready to go after him, but Piccolo told him to come back and leave Vegeta alone.
Piccolo then talks about how Vegeta's ego has grown bigger since he became a Super Saiyan and he is very disappointed of his defeat. Piccolo then tells Krillin, Tien, and Future Trunks to go and move Goku to another place. Krillin then asks where Piccolo's gonna be and he said I don't know. Krillin then asked again and then Piccolo got mad and said "Stop asking questions it's none of your concern!!! This is something I have to do alone!!!!" And with that he shot a flare blast and flew off angrily. Tien then asked why Piccolo did that and Krillin said he has a lot on his mind and that he is going off to Kami's to fuse with him into one being like they had in the beginning.
Tien, Krillin, and Future Trunks then go off towards Goku's with full speed and talk of getting him to a safer place. Also, while this is happening Vegeta is having Rage Fits and bursting his anger to the max causing his power to erupt. Vegeta then says he will destroy those androids for defeating him.
Piccolo then arrives on Kami's lookout and Kami has a flashback of when his evil self was driven out of him and King Piccolo was destroying everything when Goku appeared and defeated him and King Piccolo then spat up an egg containing the Piccolo we know today. Piccolo then asks Kami what he wants and Kami says "You have a lot to learn Piccolo"
