Dave was a MASSIVE douche to his dad. *spoilers*
The whole "when you're gone, who's gonna know" thing was a DIIIIICK move. Whytf would he say that to his own dad, someone has supported him and nurtured him and cared for him, his only parent after his mom died???
I bet he wish he could have took what he said back after his dad was *beep* murdered in a jail cell. -_-
