Gemma, Micki's roommate, smokes a lot of pot, screws a lot of casual acquaintances, swears like a longshoreman, and is generally having a perfectly splendid time at Smithson. She's nominally studying astronomy, but seems incapable of attending classes, doing any work, or, for that matter, correctly pronouncing the name of her major. She has a campus job at the college library, where the head librarian is pissing her off. She and Selena hate each other.

Unbeknownst to either her friends or her enemies, Gemma is very, very smart, and the Smithson administration will most likely continue to indulge her until she hunkers down and squeezes out an annus mirabilis. Until then, everyone has to put up with her, because she ain't going nowhere.
