Plot
While investigating a severed hand found on a beach, Doakes spots Guerrero's men watching him. After discovering the hand belongs to Tony Tucci, LaGuerta visits his mother in an attempt to make amends for naming him as the Ice Truck Killer on television. Dexter remembers that he and Harry visited this beach when he was a child, where Harry lectured him on the importance of faking emotions to make other people happy. Back at his apartment, Dexter looks through a family photo album. It appears that the Ice Truck Killer broke into his apartment to get to know him, not just leave doll parts.
LaGuerta forces Debra to watch boxes of surveillance tapes. Kara's brother continues to taunt Doakes about how he's going to get himself killed. Doakes lets him know that Ricky wouldn't come out of cover to give Kara a divorce, suggesting he's the reason she was killed. Later, a severed foot is found near an old soccer field where Dexter played in his youth. Dexter tells Doakes that the killer is sending a message that is more important than the ritual, but cannot tell him what or why. After analysis of the foot, Dexter determines that Tucci is still alive and is systematically having his limbs removed by the Ice Truck Killer. LaGuerta phones Tony's mother to tell her that her son may still be alive.
Batista repeatedly asks Dexter for his advice on an anniversary gift for his wife. It transpires, however, that they have been separated for three months due to "something he did." Batista ultimately gives her a necklace. Meanwhile, Rita and her children are being kept awake at night by a neighbor's dog. When both Rita and Dexter are met with derision from the dog's owner, Rita takes the neglected dog and drives it to a friend's house to live with her and her daughters.
