Woo appeared for the first time in the second season as a client suing a Howard Stern-like talk show host named Wick. She was suing because Wick's programs contributed to sexual harassment in her workplace. Wick claimed Woo brought suit because she had a "slutty little Asian thing going", and Woo said that she wanted to sleep with Wick because if she did, she would kill him. The character proved to be a hit, and Liu was signed on as a regular for the series.
