Chapter 48 — The Oath in the Tunnel
Ling and Lan Fan fight Gluttony, while Heinkel continues to fight Pride. Meanwhile, Mustang visits Madame Christmas to confirm that Selim is in fact a homunculus. Pride manages to overwhelm Heinkel. However, before Pride can finish him off, Edward intervenes and saves Heinkel using his automail, now reinforced with carbon. Spies from Central are shown to have followed Mustang to a hostess bar, finding out that Madame Christmas is his foster mother. Mustang then detonates the bar, and he escapes through the sewers with Madame Christmas. He then meets up with Hawkeye, Breda, and Fuery before they attempt to take over Central. Before Pride, who takes over Alphonse again, prepares to fight Edward, Fu throws a flash bomb into the air, overwhelming the shadows with light and breaking Pride's control of Alphonse. Darius then takes Alphonse away to a safer place, and Gluttony stumbles into the fight between Edward and Pride. Upon discovering that Ling and Lan Fan can sense homunculi, Pride consumes Gluttony, both to replenish his life as well as to gain a sense of smell that can detect Edward's group. Back in Central, Mustang begins his upheaval plot by capturing Bradley's wife. (Source: Wikipedia)
