Question: Any hot spoilers for The O.C.?

Answer: My O.C. mole's roommate has a friend whose sister just tested for the role of Marissa's li'l sis, Kaitlin. And like any good spy, he/she promptly forwarded me the official character breakdown. And like any good pooper scooper, I'm sharing it with you here:

Kaitlin Cooper: 14 to 17, could also be 18 to play younger, Caucasian, beautiful, hot. Marissa's little sister is back from boarding school and it's clear she's growing up way too fast. Hell on wheels, a precocious Lolita. Sexy beyond her years, cunning, intelligent, sarcastic. A bitchy bombshell, but we root for her. Recurring guest star.
