PREVIEW: Tonight's Return of GREEK

1 ABC Family's GREEK, the network's top series until the success this summer of THE SECRET LIFE OF THE AMERICAN TEENAGER, returns for a new batch of episodes tonight at 9pm ET. The show, aimed at teens and twentysomethings, ably captures a middle ground between the earnest SECRET LIFE and the over-the-top GOSSIP GIRL. Tonight's season premiere takes a page from NBC's playbook, piggybacking on the Olympic spirit as the sororities and fraternities compete in the Greek Week Olympiad. Rusty and Calvin strive to find a neutral friendship zone despite their opposing house loyalties. Meanwhile, Casey must decide the consequences of Rebecca's wild spring-break actions, and Rebecca's continued bad behavior doesn't help matters.
