Later, Carver and Herc find Bodie, but their interrogation doesn't turn up results.

When Rawls looks to make a premature arrest for three murders that are linked to D'Angelo and Avon Barksdale, McNulty and Greggs must argue for a delay in order to preserve the valuable wiretap gains they have made. Meanwhile, Wallace and D'Angelo struggle with their consciences after Avon pays them blood money.

"A man must have a code." - Bunk. Tipped off by the wire, Greggs, Herc, Carver and Freamon make a bust, but the incident makes Avon and Stringer suspicious, leading them to close shop in the Pit. Meanwhile, Bunk and McNulty look for another witness in the Gant slaying and hunt a suspect known as 'Mr. Bird.'

"Come at the king, you best not miss." - Omar. An unlikely source gives McNulty the tag of a car driven by Stringer Bell. Meanwhile, Greggs and Carver bust a congressional aide carrying dirty cash, but are forced to let him go. Omar earns his 'loose cannon' moniker.

"This is me, yo, right here." - Wallace. The low-rise pay phones are out of service, so McNulty and Daniels try to keep pace by tapping Barksdale's office.

With the detail's future hanging in the balance, Daniels faces off against Burrell and his political allies.
