Flame of Vengeance

With rumors of a coup spreading, Central's citizens tune in to Radio Capital, where Mrs. Bradley joins Mustang's platoon on air from the seized studio. She explains that Central's forces meant to kill her alongside the colonel's men, and Breda drops the bombshell that someone bombed the Fuhrer's train, leaving Bradley missing. When Klemin orders the station shut down, the master feigns being held hostage and hangs up, while Ross delivers a stirring speech that turns the public toward Mustang's cause.

Underground in the white hall, Mustang incinerates the swarm of Mannequin Soldiers pressing Edward's group in a single torrent of flame. A tunnel collapse sends May and the restored Envy tumbling into their midst, and Mustang, recognizing the homunculus, demands to know who killed Maes Hughes.

Envy tries to pin the murder on Ross, but Mustang insists he always knew her innocent. Finally admitting the crime, Envy taunts him by taking the shape of Hughes's widow Gracia, and a fully enraged Mustang readies both flame gloves, swearing to burn away the creature's tongue first. He sends Edward and Scar ahead so he can face the homunculus alone, and Hawkeye stays at his side.

Mustang boils Envy's eyes and bathes his massive form in fire, forcing the homunculus to shrink back and flee. Roy gives chase, ordering Hawkeye to stay behind, but she disobeys and plunges after him. Envy, spotting Riza wandering the maze, senses an opportunity. When Hawkeye and Mustang reunite in the tunnels, the colonel says he lost the trail and tells her to stick close, but she raises her pistol and aims it at the back of his head.

The episode adapts the manga chapters covering the archenemy and the flames of vengeance, and its title card bears the flame alchemy circle. Envy's transformation animation is lifted from the earlier installment Bite of the Ant. Where the manga's Riza hesitates only a moment before following Roy, this version keeps her in place until the noise of fighting drives her forward. Throughout, the shadows of rage under Roy's eyes deliberately echo the scar on Scar's face.
