Alicia first encounters Leonard and Sheldon when they meet in the lobby. Sheldon's random, odd question, annoy her at first, but she answers everything to his approval, and he accepts her presence. Leonard, Howard, and Raj immediately fawn over her and do her multiple favors, and she flirts with all of them except Sheldon. Penny becomes annoyed that Alicia is blatantly using them and jealous that Leonard is doing favors for Alicia while things he promised Penny long ago remain undone. Like Penny, Alicia is an aspiring actress, although more successful, and has managed to get small television and commercial roles.
Penny tries to get the guys to pay more attention to her, but Alicia is a tough competitor; when Penny buys Chinese food for the guys, Alicia comes by and lures them away by asking if someone will drive her to an audition, promising more Chinese food as a reward.When Penny encounters Alicia in the laundry room, it becomes clear Alicia is really only interested in the guys for their favors. She asks Penny how much physicists make, but is obviously disappointed with the answer. When Alicia mentions the guys are going to set up her satellite dish and paint her bedroom, Penny decides the gold-digging has to stop, so she calls her on it, prompting Alicia to imply Penny is a hypocrite because Penny does the same things. When she calls Penny a bitch, it visibly infuriates her, starting a fight that spills out into the lobby, where the guys watch in horror (or, in Howard's case, excitement). Later, Penny is seen with a black eye, suggesting Alicia won. The guys stop doing favors for Alicia, though, and Howard mentions she is dating an executive from the show "C.S.I.", on which she appears. They hear Alicia having sex with him upstairs, and Sheldon believes they are jumping on the bed.
