Season 3

Crazy

Aria, Spencer, and Emily hear CeCe use a quote Alison would always say. CeCe overhears them and approaches them. She introduces herself as one of Alison's friends and said Alison told her about all of them. After leaving, the Liars note how alike Alison and CeCe are and debate whether it was CeCe that looks and acts like Alison or vice versa. When Emily and Nate were looking for something he wanted to get Jenna Marshall for her birthday, CeCe could tell Emily didn't like it and assumed she had feelings for Nate. Thus, she steals Jenna's number from Emily's cell phone, and calls Jenna saying she was Nate's girlfriend, and wanted Jenna to back off. Emily is surprised, but CeCe thinks she is grateful.

The Kahn Game

CeCe tells Spencer she knows a guy who can help her get into the college she wants because she is an alum of UPenn. After Aria and Spencer ride with CeCe to the party, CeCe plays a round of Truth with Eric Kahn, Noel's older brother. She promises Spencer that she will give her college application to the admissions counselor, but at first it is unclear what she did with it. Spencer suspects that CeCe in fact did not come to the party to give the application to "Steve", but in fact, made him up, so she could hook up with Eric. Later, Spencer receives an email from the college acknowledging receipt of her application, thus confirming that CeCe did, in fact, give it to the guy.

Single Fright Female

CeCe is seen posting something at the front of the school when Spencer asks her what she's doing. CeCe tells her she's trying to spread the word about a fashion show. In a flashback, CeCe and Alison talk in her car, and Alison tells her about how she'd set up Paige by writing her a love letter, pretending to be Emily. CeCe says she's proud of her. When Paige appears for the setup, Alison confronts her and threatens to tell her father, who is the deacon at the church. Paige screams at Alison to give her the note back, but Alison says that she owns her now. CeCe gleefully speeds away from the scene with Alison.

Out of the Frying Pan, Into the Inferno

When Emily ask why, we flashback to a night when CeCe was hanging out at a crab shack and spots Alison, she tells her that she is 2 weeks late and scared she is pregnant because she didn't use protection every time.

CeCe later leaves Aria and Wesley alone to go get some dinner and never returns.
