David “Walky” Walkerton

Walky is his parents’ favorite child. He’s smart and he doesn’t get into trouble, but he could be a little more ambitious. He’s here at college because his parents want him to be, but mostly what he wants to do is watch television and goof off. Lucky for him that good grades came easily to him (in high school), so he figures college will be everything he’s ever wanted. No parents, no structure order — just eating McNuggets whenever, wherever.

Walky is Sal’s twin brother, and the two very different siblings haven’t really spoken much in a long while. He’s Mike’s roommate and he’s also somehow Dorothy’s boyfriend. She is way, way above his station.
