Dexter struggles to keep in control when the still-unseen Ice Truck Killer leaves the dead body of Valerie Castillo, Dexter's most recent kill, at the auto yard, which puts Dexter in dangerous proximity to being discovered by his colleagues, which is worsened when a young Cuban boy is also found at the scene claiming to have seen who killed Mrs. Castillo. Dexter must stay one step ahead of his own friends by tampering with Vince Masuka, the medical coroner's, e-mails, then tries derailing Debra's suspicions to a copycat killing, and always half-expecting to be arrested. Lt. Laguerta tries to be compassionate to the little Cuban boy whom she tries to asks for a sketch of the man he saw. Meanwhile, Rita gets an unpleasant phone call from her abusive ex-husband, Paul, who has just gotten paroled from prison and wants to visit Rita on her daughter Astor's birthday. Dexter also recalls a row he had with his stepfather over including Debra in their hunting trips. Also, Doakes asks Debra to accompany him to dinner at his mother's house just to distract his overbearing mother and older sisters from meddling in his personal life.
