The Oath in the Tunnel

Lan Fan and Lin fight Gluttony, and Heinkel continues to fight Pride. Meanwhile, Roy visits Madam Christmas to confirm that Selim Bradley is in fact a homunculus. Pride manages to get back the upper hand in the fight and wounds Heinkel. However, before Pride can finish him off, Ed intervenes and saves Heinkel using his northern automail, now carbon-reinforced. Spies from Central are shown to have followed Roy to Madam Christmas's bar, and as they find out that the madam is Roy's foster mother, the bar is blown up by Roy, who escapes through the sewers with Madam Christmas. Roy then meets up with his subordinates before they attempt to take over Central. Pride takes over Al again, but right before he fights Ed through Al, Fu throws a flash bang into the air, overwhelming the shadows with light and breaking Pride's control of Al. Darius then takes Al away to a safer place, and Gluttony stumbles upon Pride and Ed's fight. Upon discovering that Lan Fan and Lin can sense homunculi, Pride consumes Gluttony, both to replenish his lives as well as to gain a sense of smell that can detect Ed and his group. Pride then smells Hohenheim, who has met up with Darius and Al. Back in Central, Mustang begins his upheaval plot by capturing King Bradley's wife.
