Before Joey meets up with her friends at her dorm room, Jack and Jen tell Audrey all about Joey's past love life which included having two boys fight over her or as Jen puts it, not really fighting as much as it was "a series of long ponderous conversations".
At the frat party, Joey thanks Audrey for not giving up on her even though she's not the most mellow easygoing roommate and then invites her to hang out with her and her friends at Grams' house. Audrey declines the invite saying that it's "sweet but it sounds kind of lame".
