"I had such fuckin hopes for us." -- McNultyFrustrated in his grass-roots reform efforts, Colvin arms himself with intelligence from Daniels detail and personally delivers a message to the next level of corner management. McNulty sees Stringer Bells legitimate business dealings as a sign that he is now unreachable as a drug target. Bubbles shakes the tree for Johnny one more time; Carcetti quietly seeks to fix the program for protecting states witnesses after another one is killed; Omar struggles with dissention in the ranks; Stringer hard-sells his new business model to an under-whelmed Marlo. Greggs surveillance gives McNulty reason to smile, and then he takes an interest in politics. Cutty flexes his muscle and continues to slide back into the life; and Avon returns from prison.
