Veronica, who believed that she had been raped the previous year at a party, discovers that she and Duncan had sex while under the influence of GHB; Duncan left that next morning because he believed Veronica was his sister. Veronica spends time with her boyfriend Logan in his pool house, but discovers a hidden video system linking to cameras focused on the bed. Veronica is shocked and goes home, only to find her mother Lianne has returned from rehab. Plot After reading a newspaper article revealing Koontz's innocence, Duncan demands the truth from his parents, Jake and Celeste Kane (Lisa Thornhill), who tell him that they arrived home one night to find Duncan covered in blood and holding Lilly's body.
