Olivia walked in on Caitlin while she was visiting Trey. Caitlin told her mother that she should have been there for her, like she had always been there for her mother. She said that she hated Olivia and that she would never forgive her. Caitlin told Trey that Olivia may have given birth to her, but that she didn't deserve him, and that she'd kill anyone who tried to take him from her. Olivia decided that she should have killed Francesca while she had the chance. (thetvdb.com)
