S1E4 · Old Cases

Epigraph: "Thin line 'tween heaven and here." - Bubbles Landsman makes a deal with major William Rawls that McNulty can return to the homicide unit with a clean slate if the detail wraps soon. Bodie easily escapes from the facility he is held in and challenges D'Angelo upon his return, who boasts about killing Avon's ex-girlfriend Deirdre Kresson for him, an old case which McNulty and Bunk investigate and find a previously unnoticed shell casing. Browning chooses jail over flipping on the Barksdales. Avon puts out a bounty on Omar's crew while Stringer wonders if the Pit has a mole. As McNulty explains the requirements for a clone to the detail, Freamon reveals that the number he saw is likely D'Angelo's. McNulty turns up to Greggs's apartment drunk, who explains that their inability to monitor their targets inside buildings qualifies them for a clone.
