Arley: I want to wear the green dress.
Trevor McKenney: You look like a vampire in that.
Arley: Jesus, you are really somethin'.
Eugene: Thanks. I appreciate the euphemism. I always wanted to be somethin'.
Eugene: Jesus Arlene, he doesn't have to. All he has to do is not love him.
Arley: I can't reject you, you're too quick for me.
Trevor McKenney: I think some people are too scared, or something. I guess it's hard for people who are so used to things the way they are - even if they're bad - to change. 'Cause they kind of give up. And when they do, everybody kind of loses.
Trevor McKenney: Are you saying you'll flunk us if we don't change the world?
Eugene: Well, no. But you might just scrape by with a C.
Sidney: The world is a shithole, pardon my French an' shit.
Trevor McKenney: Is the world just shit?
Eugene: OK. You know, I'm going to have to consult my spirit guides here, because you tell me that Trevor is withholding from you, but you won't tell me anything specific and you still want me to sit here and divine why.
Arley: Divine why? You always talk like that?
Eugene: Yes.
Arley: You go to some big, fancy school?
Eugene: Yes.
Arley: Think you can stop rubbing my nose in it?
Chosen answer: The one who stabbed him was not. The others were there because they did not mean for Trevor to get stabbed and killed so now they feel guilty. They were showing Arlene they were sorry.
They were sorry for killing him.
Only one of the bullies killed him. The others were bullying, but didn't think the other would kill him. However, they still had remorse and were showing that remorse to the mother.
The one who stabbed him was probably arrested offscreen.
