We told you. We freaking told you. We told you Luke is awesome and actually has an interesting story arc. The producers of The OC handle some sensitive subject matter with surprising sensitivity. Which is more than we can say for Alex, Jon, and Tyler, who spend the better part of an hour ragging on a (hopefully) long forgotten internet hate campaign while making cuckolding jokes.
Episode description from Hulu:
"Seth struggles to make up for the way he acted over the holidays; Ryan and Luke become partners for a history project."
