unknown to the police, nick is merely distracting them while his brother, joey (jamie bell), and joey's girlfriend, angie (genesis rodriguez), break into englander's vault across the street, using the cover of nick's theatrics to detonate explosives on the roof to gain entry, in order to steal the diamond and ultimately prove nick's innocence. cassidy must make use of double entendres in order to provide instructions to joey and angie through an earpiece whilst not revealing their plan to the police. meanwhile, dougherty informs marcus of nick's identity, and marcus orders the jewelry store's security to check the vault. joey and angie are able to evade them by hiding in a ceiling vent, but do not find the diamond. they deliberately set off the heat-sensing alarms, tricking englander into retrieving the diamond and ambush him in his office, stealing the diamond at gunpoint and forcing him to handcuff himself to his safe. meanwhile, nick's ex-partner, mike ackerman (anthony mackie), arrives at the hotel with evidence that nick is planning something and demands to be allowed into the hotel room. lydia does not trust him, and dougherty backs her up. ackerman claims he has found bomb schematics in a storage unit nick rented and is convinced that he will detonate an explosive somewhere. while the crowd is evacuated by the bomb squad, lydia, believing in nick's innocence, calls internal affairs and discovers that three of the cops employed by englander were suspected of being corrupt: ackerman, marcus, and a deceased officer called walker, whose name cassidy uses when checking into the hotel.
