Freamon, Bunk and Beadie travel to the Port of Philadelphia to investigate the murdered crewman. Using security tapes, they place Serge at the scene of the killing. Under questioning, Serge is forced to admit that he was present when Vondas killed the crewman in retaliation for his murder of the Jane Does. Elsewhere, Greggs' downbeat attitude about parenthood causes tensions with Cheryl. The FBI places Nick and his family in protective custody in a basic motel. The next day, Nick leaves the hotel and is unable to find a day's work at the docks. Under pressure from Daniels, Serge reveals a location that The Greek uses for meetings. Daniels moves on The Greek's hotel, unaware that Vondas and The Greek are already leaving the country. With the port case over, Greggs and McNulty convince Daniels to use his new unit to go after Stringer and Joe. Fitz tells Daniels that the leak was not from his agency, but rather likely from the FBI's counterterrorism office, who would find The Greek's vast network to be valuable for the War on Terror. Valchek opens a letter from Australia with a photo of the surveillance van that is still being transported around the globe. Valchek sadly whispers "rest in peace" in Polish.
