"Reformation" is the tenth episode of the third season of the HBO original series, The Wire. The episode was written by Ed Burns from a story by David Simon & Ed Burns and was directed by Christine Moore. It originally aired on November 28, 2004.

The title refers to the theme of season three with various characters struggling to initiate reform on a personal and citywide level. In this episode Cutty's attempts at personal reform come to fruition when he starts his gym, Colvin's attempt to reform the drug war are exposed and Brother Mouzone remarks on the empty political promises of reform in Baltimore marked by the collapse of the towers.

This phrase is originally said by Prop Joe in regards to the Barksdale organization. However, the line may also allude to several 'leadership crises' present in the episode, including: Cutty learning how to coach kids, Colvin legalizing drugs without Commissioner Burrell's knowledge, Carcetti's dilemma over whether or not to betray Tony, and (of course) Avon refusing to back off his war with Marlo.

Although credited, Wendell Pierce and Jim True-Frost do not appear in this episode.

Young Stanfield dealers Justin and Jamal leave a convenience store and hear gunfire nearby. They rush away from the store and come across the body of LaTroy, a Stanfield lieutenant. Their colleagues Snoop and Tote pull up in a truck and Snoop orders them to get in for their own safety. Meanwhile, Marlo Stanfield remains safely protected by numerous bodyguards. Marlo and Chris Partlow set up a night time ambush for Devonne, the woman who acted as bait in a failed trap for Marlo organized by Avon. When she emerges from her home, Marlo shoots her twice (one in each breast) and when she has fallen fires a third bullet through her mouth. Partlow assures him that the murder was necessary.
