"[1][2] The first chapter of Greek opens as incoming freshman, Rusty Cartwright (Jacob Zachar) matriculates at Cyprus-Rhodes University (CRU).
Casey gets even with Evan by sleeping with her ex-boyfriend, Cappie (Scott Michael Foster), the president of the party fraternity, Kappa Tau, which Rusty joins.
Rusty navigates the balance between being a fraternity brother and honors engineering student, with the help of Casey, Cappie, his roommate Dale (Clark Duke), friend Calvin (Paul James), and his first girlfriend, Jen K. (Jessica Rose).
When Jen K. writes a story for the school paper exposing Greek secrets, Casey finds herself established as ZBZ's interim president.
All this activity leads up to Spring Break when Rebecca's father's scandalous proclivities hit home, forcing a drunken confrontation with Cappie, an unplanned kiss on the beach between him and Casey, and a reconciliation between Rusty and Calvin.
Evan continues his relationship with Frannie, begun over Spring Break, his competition with Cappie heats up, and he accepts a multimillion-dollar trust fund from his parents, despite their attached strings.
Casey begins dating Rusty's RA, Max (Michael Rady), a polymer science grad student, of whom Cappie grows jealous.
Frannie begins a bid for a second presidential term, competing with Casey for the title, but unbeknownst to anyone Rebecca and the other pledges vote to elect Ashleigh (Amber Stevens).
The chapter ends on Hell Week, when the pledges prove themselves to their houses, Casey and Max face the dilemma of a long-distance relationship, and Frannie establishes a new sorority, taking half of ZBZ with her.
