Season 5, Episode 2, "Unconfirmed Reports"

WARNING: SPOILERS AHEAD! Dee-Dee makes her final appearance on the show as she tells her story in an NA meeting attended by Bubs. Bubs himself, is being pressured by Walon to tell his full story of how he got clean, thinking that it will be the only real way he could ever get true clarity. Clay Davis feels the walls closing in on him and lashes out at Burrell, who was once one of his staunchest allies. Marlo, feeling emboldened, goes on a tear and starts ordering home invasions, homicides, and the like, while also trying to get in contact with Sergei at Jessup, but he runs into the obstacle of having to talk to a now-pathetic Avon Barksdale. The tension between Gus Haynes and Scott Templeton begins to brew as we get our first taste of Templeton's untrustworthy nature concerning the "EJ" story. McNulty, spiraling back into the throes of alcoholism, decides to initiate a farcical hunt for a serial killer that doesn't exist so that he can gain some leverage to go back after Marlo.
