After sending Spence after the DA, Bette and Olivia practiced their story. Olivia worried that Caitlin might have planted the gun in her house to begin with, but Bette talked her out of it. Caitlin told Cole that she was in the process of planting the gun in his room when she was caught, so that once he'd been sent to prison, she'd never have to think about him again. Cole insisted that Caitlin was incapable of hating someone like she claimed to hate him and Francesca. Before Ruiz took her down to book her, Caitlin left her wedding ring on the table. (thetvdb.com)
