Dragon Ball Kai - episode 78 - 23 Oct, 2010

Goku continues to train Gohan, who is still trying to achieve the Super Saiyan form. Meanwhile, Vegeta effortlessly pushes Cell around and inflicts significant damage. When Cell uses Vegeta's own Galick Gun to no effect, he realizes that he will not be able to absorb Android #18. Enraged, Cell goes on about how if he was able to absorb #18 then he would become his perfect form and be able to defeat Vegeta easily. He attempts to persuade Vegeta into letting him absorb #18 by appealing to the Saiyan's passion for fighting strong opponents. Not far away, Krillin contemplates whether or not to use the emergency shutdown controller, and he has trouble deciding due to his embarrassing moment with Android #18 during their first encounter (when Android #18 kissed Krillin).
