Epigraph: "I need to get clean." - Sobotka The detail arrests several Greeks and stevedores, including Sobotka. They leave Vondas on the street and have Russell tail him, mistaking his lawyer for the Greek while McNulty unwittingly catches the real one in a photograph. Stringer convinces Omar that Mouzone helped kill Brandon Wright, so he breaks into his motel room and shoots him. Mouzone convinces him that he is innocent. Ziggy bitterly expresses his hatred of Sobotka prioritizing the union over him when he visits him in jail. As his arrest tanks his run for treasurer, Sobotka agrees to cooperate with the detail so long as no stevedores are implicated. He goes to meet with Vondas and the Greek to get Ziggy freed, only for Koutris to call them as he arrives to relay that he met with the FBI.
