When the live feed was almost ending, she was saying how Gina didn't want her there because Sophie left. This is after asking Sam and Joe what Gina had said about her and Dexter. Also the truth came out when she said Dexter had said that if Gina had been single he would have probably have gone for her. She is looking for a fight with Gina she won't be able to handle.
