For some reason though, he seems distraught on having to return to the lab, but it is not revealed in that episode. The androids disagree, and don't like being commanded, and say so. Meanwhile Kuririn wants to escape the Androids. Vegeta wants to stay. Vegeta states that that's not unusual, and that it is perfectly normal to kill anyone you don't like.
Trunks shoots a blast into the cave which the lab is in, but it has no effect.
They ask him if he was made to kill Son Gokuu, and he replies to the affirmative. The androids fly away. Suddenly the Z teamers realize the adroids are flying towards Gokuu's house. Vegeta is mad that the androids paid him no notice. Vegeta insists on following the androids despite numerous warnings from Trunks.
