Thuliso Dingwall

The Machine identifies Darren (guest star Astro), a teenager whose brother was just murdered, as the next POI. Now, Reese must struggle to protect the teen, who's hell bent on avenging his brother's death.

Valchek leaks details of the Braddock case to Carcetti, who contemplates how to best leak it to the press. The ensuing negative attention turns Royce against Burrell, who takes the heat while Rawls comes to the rescue. At school, Prez's reward/punishment program meets with mixed results, and Colvin looks to restore order by separating disruptive 'corner' kids from more attentive 'stoop' ones. His poster boy for the former: Namond. Chris tries to enlist Michael into Marlo's ranks, spooking Randy along the way. At the detail, Marimow sets up a series of street-level 'rips' targeted at Marlo, but his subordinates--and Pearlman and Daniels--are skeptical. Later, Herc and Sydnor plant a hidden camera at Marlo's meeting place, with unexpected results. Burned by Omar, Marlo gets Chris and Old Face Andre to frame his nemesis. Bubbles's efforts to keep Sherrod in school only get him humiliated. Angered by Royce's double-dealing, State Delegate Watkins decides to sit out the campaign, sending Carcetti and Wilson rushing to make their pitch. Although Bunk and Freamon come up empty in their body-hunting search, Dukie knows where the 'special dead' might be hiding.

With Election Day approaching, the three mayoral candidates make last-minute appeals. Carcetti wrangles for votes as he responds to a potentially devastating smear. Norris and Greggs get a lead on the Braddock case, but end up being detoured. Following through on a promising video lead, Herc finds out just how elusive Marlo can be. With De'Londa's well running dry, Namond is asked to step into his father's shoes. Omar is fingered for murder, but McNulty and Bunk suspect a frame. At school, Colvin's special class gets its first enlistees; Prez solves Dukie's wardrobe woes; and Randy is called out on a serious transgression, forcing him to confess to another one. Cutty figures out why Spider, and Michael, might have been avoiding him. On Election Day, Carcetti is miffed when he learns that State Senator Clay Davis has been double-dipping; later, he contemplates breaking some old habits for the good of his career.

With a bounty on his head, Omar calls in a favor to Bunk. The election finally over, Royce and Carcetti make their peace, and contemplate their respective futures. At school, Prez 'tricks' his students into learning math; Namond finds that the old rules no longer apply; a disillusioned Cutty ponders his job future; and Randy is cleared to return to class. Marlo looks to 'smoke out' his pursuers, infuriating Herc, who begs Carver to help. Expecting the worst, Pearlman gets surprisingly good news from her new boss. Following some high-profile appearances, Daniels's star seems to be on the rise. Bubbles finds his rolling business, and relationship with Sherrod, sabotaged by both sides of the law. Finally, Greggs uses 'soft eyes' at an unsolved crime scene.

In the Season Four finale, the bodies from the vacants pile up while Burrell offers his support to Daniels and admonishes Rawls for crossing him. A distraught Bubbles finds himself at his wit's end after his revenge plan backfires. Proposition Joe looks to the Co-op to defray shipment losses, but finds them not so cooperative. Attempting to get Namond off the corners, Colvin visits Cutty in the hospital to arrange a prison sit-down with Wee-Bey about the boy's future. Omar divides the spoils from his latest heist, then hatches an audacious new plan. Carcetti responds to the governor's school-budget offer; Carver tries to buy time for Randy; Dukie has trouble adjusting to his new peers; Marlo gives Michael new responsibilities on an old corner; Colvin and Parenti take their proposal to City Hall; Namond returns to gen pop; and McNulty looks to pay back an old debt he owes Bodie.
