Hard Cases

"If I hear the music, I'm gonna dance." -- Greggs
The medical examiner determines that the bad package which killed five inmates and hospitalized eight others was cut with strychnine, so the heat is on to close the case quickly; as the pressure mounts to deliver Omar's testimony in the Gant case, McNulty enlists Bubbles in the search, but an unhappy Omar finds Bubbles first; Dee confronts Avon about the bad package and washes his hands of the business; Daniels and Burrell strike a deal on the detail, but Rawls refuses to reassign McNulty while okaying Greggs, Hauk and Lester; Stringer continues to struggle with poor quality product from his suppliers; Avon brokers a deal to give up Tilghman for a reduction in his sentence; McNulty continues his efforts to identify his floater; pleased with the outcome of their prior deal, the Greeks come to Nick and Ziggy with a request for bulk chemicals; after Sobotka chews Nick out for stealing the container and tells him to keep a low profile, Nick passes the word to his cousin, which falls on deaf ears;  Daniels and Greggs get the silent treatment in their respective homes after they break the news of the new detail to their wives; McNulty signs the separation papers as he asks Elena for another chance; Bunk, Lester and Russell terrify Sobotka when they drop by the bar for a little quality face time.
