After his model-home hiding place has gone up in flames, Ryan (Ben McKenzie) ends up back in juvenile hall -- and, inevitably, Sandy (Peter Gallagher) shows up to plead Ryan's case. Back in Newport, Sandy's wife, Kirsten (Kelly Rowan), must deal with the unbridled anger of her son (and Ryan's new best friend), Seth (Adrien Brody); and the community is "invaded" by Ryan's unreliable mother, Dawn (Daphne Ashbrook) -- who, despite repeated promises to her son, has gone back to binge-drinking and gambling. Also, the financial secrets between the Cohens and the Coopers are brought to the forefront during "Casino Night" in the O.C. ~ Rovi
