Dexter is sent to investigate a horrific blood-soaked crime scene, which he usually enjoys, but is taken aback by a long-suppressed memory of a childhood trauma instead. Rita is charged with assaulting Paul and could lose her children in a custody battle. However, when Dexter finds out, he decides to remove Paul from his and Rita's lives, but by framing him rather than killing him. Angel investigates a hunch regarding the Ice Truck Killer concerning amputee fetish; he turns to Rudy for help but ends up getting stabbed in the parking lot. Meanwhile, Rudy displays a growing interest in getting to know Dexter, particularly in the lately awoken trauma he had recently experienced.
Dexter receives a jar with blood with the keys of room 103 of the Marina View Hotel inside. When Debra and Sergeant Doakes arrive in the crime scene, they get impressed with the bloodshed and calls back-up and forensics. Dexter recalls suppressed memories from his childhood and is incapable of staying in the room while Rudy uses Debra to get close to Dexter. Meanwhile Paul presses charge against Rita for being assaulted and she is summoned to the precinct first and later to court. Due to the risk of Rita losing the custody of the children to Paul, Dexter gets emotionally evolved and fixes the problem. When Angel finds a possible lead to the Ice Truck Killer with a prostitute, he consults Rudy about cases of acrotomophilia, i.e., people attracted to persons with an amputation. Lt. Laguerta faces Captain Matthews and tells the truth about the Ice Truck Killer to the press.
In this great episode, Dexter recalls a traumatic experience from his childhood when he lost his mother and certainly the motive for his dysfunctional behavior. Debra is completely blinded by her crush on Rudy and Dexter and she are giving ammunition for the next steps of the Ice Killer Truck. Dexter resolves the problem of Rita but exposes himself to Paul. Angel gets close to the Ice Truck Killer and lets see if he will survive to the attack. My vote is eight.
