Nick Baumgart

What on Earth did this poor kid do to end up on Eric's shit list? I'm just now finding out he was actually *friends* with Eric/Dylan/Zack, but what caused the fallout? To write something like "Everyone at school hates this immature little weakling", and calling him a "f*ggot" when they were planning to egg his house or whatever the hell it was....and remember, this is from the kids who are supposedly at the bottom of the Columbine social pile.
He seems to have done okay for himself in the time since then.

Off-topic: those "I'm Poppy!" videos on Youtube are really stupid now and it's time to end them.

Maybe Nick was telling somebody some general secrets, who knows) It seems to me that he is a rather cunning guy ...

From the looks of it, Nick didn’t do anything to deserve their spiteful treatment of him. According to Brooks, they apparently started distancing themselves from him and making fun of him behind his back because they thought he had an annoying laughter and that he laughed too much.
They generalized their hatred for bullies by hating on everyone, including people who’d never wronged them.

he was a coward who never stood up for anyone who was mistreated.
