After learning that he was filmed while cleaning his boat at the marina, Dexter becomes desperate and tries to delete the videofile, which he eventually manages to do before computer upgrades enable its viewing by his colleagues. A mock killer mimics, and claims to be inspired by, the Bay Harbor Butcher, and unless the police find him, the FBI may take over the case completely. After learning about his mother's secret relationship with his foster father, Dexter questions Harry's motives about his own adoption. At Rita's mother suggestion, Dexter brings Lila to dinner, and when Rita finds out that Lila accompanied Dexter on his road trip, Rita breaks up with him. Dexter and Lila leave together and have sex later.
