Was Denny also a bad guy?

*Spoilers*

Maybe not as bad as Jim, but he had no problem leaving Edward behind. The only one in that group of people who weren't snakes, in my opinion, was Kim.

Nah, if anything Denny was just an enabler for Jim's behavior. You can tell he looks very conflicted when Kim is telling him to turn around. Maybe a part of him actually wanted to, but Jim is his best friend (or so we assume anyway) so he would probably listen to Jim first before Kim. That and like another person already said, he probably didn't want to get arrested just like the other characters. Suzanne also appears very nervous and conflicted in this scene but she doesn't say anything.

That said, I do like the moment where Denny starts saying something like "Jesus. Maybe she (Kim) was right about you-" but then Jim cuts him off. (In the scene right before he starts driving drunk and almost hits Kevin.) That to me indicates that he's gone through some character development and is beginning to see Jim's flaws, despite what a minor character he is.

While we're on the subject of Kim and Jim's friends, anyone else find it weird that Suzanne totally disappears after the robbery scene? We never see her again.
