S2, E19: Nathan's Uncle Cooper (Michael Trucco - "Pensacola: Wings of Gold") visits Tree Hill to take Nathan and Lucas on an auto racing trip. On the track, Nathan and Lucas are challenged to a contest by beautiful Daytona (Schuyler Fisk - "Orange County") and her obnoxious brother Garrett (Stuart Lafferty, series star James Lafferty's real-life brother), but things go horribly wrong when Nathan loses control of his car and crashes into a wall. Meanwhile, Deb's addiction to pain pills intensifies, and Dan exposes Andy's (recurring guest star Kieren Hutchison) relationship with Karen to Andy's class.
