Recapping episode 21 of season 2 of The O.C.. We tackle one of the more serious episodes (at least in part) with returning champion Nickel! Bienvenido a Miami as Sandy, Seth, and Ryan visit the Nana. Seth's superfluous storyline is overshadowed by an all time Sandy plot getting rid of "Bobby." Meanwhile, Kirsten is finally over the edge re: Carter, and the Marissa / Trey interaction takes a dark turn.
