A show I used to watch

So I use to watch this show maby on Cartoon Network but it was live action, its kinda hard to explain but I'm going do my best, it was about 3 college kids and one had like special abilities so he found I think he's grandfather dead he's been poison by a dart, I don't remember much about the show just bits and pieces, but I do remember a scene where he met some one he knew since he was kid and It go to a flashback and he's hanging in a net and he says that was a long time ago, really when you pee your pants it seems like yesterday, I hope this makes sense it's 1 am and I started thanking back to this.
