Alicia

Alicia is Leonard, Penny and Sheldon's neighbor in the apartment above them. She appears in Season 2 Episode 19 "The Dead Hooker Juxtaposition."

Overview
Alicia first encounters Leonard and Sheldon when they meet in the lobby. She is slightly put off by Sheldon's random and odd questions but he accepts her presence when she answers everything the way Sheldon likes it. Leonard, Howard, and Raj immediately fawn over her and do her multiple favors. In turn she with them. Sheldon is the only exception, and she doesn't bother trying to flirt with him. Penny becomes and  by how the guys are acting and sees that Alicia is clearly using them for favors (even though she is not completely innocent in this category). Like Penny, Alicia is an aspiring, but far more successful, managing to get small television and commercial roles.



Penny tries to get the guys to pay more attention to her, but Alicia proves to be a tough rival; when Penny buys Chinese food for the guys, Alicia comes by and guides them away by asking for them to drive her around, offering Chinese food as a reward. Naturally, the guys quickly forget about Penny.

When Penny encounters Alicia in the laundry room, it becomes apparent Alicia really is only interested in the guys for their favors. She questions Penny on how much scientists make, and is obviously not pleased with the answer. Penny calls her on it, prompting Alicia to imply Penny is a hypocrite as she does the same thing. She adds insult by calling Penny "bitch," resulting in a furious Penny to get into a fight. They spill over into the lobby and are watched by the guys in horror (and excitement by Howard). Later, Penny is shown with a black eye, implying Alicia may have won. Howard reveals she is seeing an executive from the show she is working on. They then hear Alicia having sex with him upstairs, which Sheldon confuses with them "jumping on the bed."
