It is revealed to the audience that Rudy Cooper is actually the Ice Truck Killer. After attempting to kill Det. Batista, who was closing in on him, Rudy proposes marriage to Debra. But this is a ruse to kidnap her and use her as bait for Dexter. Rudy 's clues lead Dexter back to his childhood home, where Rudy is holding Debra. Dexter recalls now that he had an older brother who was also in the container when their mother Laura was murdered. Rudy Cooper is actually his older brother, Brian Moser, who was not adopted and spent much of his life in mental institutions. Like Dexter, he is a serial killer but not bound by a moral code. Rudy reveals that he has been searching for Dexter for years and was happy to realize that his younger brother was also a killer. For months now, he has been leading Dexter to him and helping his younger brother recover the memories of their shared childhood trauma. Rudy then reveals a room covered in plastic, where an unconscious Debra is naked and taped to a table. Rudy has arranged the room to be just as Dexter prefers for his own kills, and says that they will kill Debra together to cement their bond as brothers. Dexter says he wo n't kill Debra and Brian protests that his brother "ca n't be a killer AND a hero. '' Dexter saves Debra from Brian just as she wakes up and Brian escapes as the police arrive.
