Thanks to TV Guide Online’s Michael Ausiello for tipping us off to his column today, which includes two items full of O.C. spoilers (scroll down). Read at your own risk if you want to learn the fate of Zach (Michael Cassidy). Also, let’s just say that Marissa (Mischa Barton) will face a devastating humiliation, and Summer (Rachel Bilson, left) will return to what creator Josh Schwartz calls ”bitch mode.” The catalyst is Summer’s new foil, the power-hungry Taylor Townsend, to be played by Autumn Reeser. Welcome to The O.C., bitch. (Sorry, couldn’t help myself.)
