Marissa Cooper
The O.C.
Marissa Cooper
Kelly Rowan
If there was a prize for the person most part of the in crowd, Marissa would definatly be in contention. Marissa lives with her two parents, next door to the Cohens, although despite this she has had little contact with Seth, as he often points out.
She starts off by dating Luke, which she has been doing basically forever according to Seth although it is clear when Ryan arrives that she has feelings for him, most notably in the early stages in episode 2 where she leaves the party with Luke to go see Ryan.
