A great moment from Kuririn and it's always fun to have him play a part in the story. Sure, it's because of some kind of crush on C18, but we've seen from the start the cyborgs aren't actually that evil. C18 has done nothing to deserve to die, and it's definitely the right call from Kuririn.
I like how Cell plays on Vegeta's pride. Not a fan of Vegeta appearing so dumb at this point though. Vegeta was the best character in the Namek arc because of his intellect and all of the planning he did against stronger opponents. Now he's just a big stupid brute.
Also, it's pretty obvious we will soon have a change of power again. It feels like we've been here before with the villains and heroes constantly changing who's on top.
