Fullmetal Alchemist: Brotherhood - episode 25 - 26 Sep, 2009

Edward and Ling find themselves in a dark place and realize they are inside Gluttony's stomach, as they try to find a way out. May is worried about Shao Mei, explaining to Yoki about their circumstances, so Scar decides to help search for her. Edward and Ling are approached by Envy, who explains that Gluttony was a failed attempt at recreating the Gate of Truth, and that there is no exit. Envy, after revealing that he was the one who started the Ishval civil war, transforms into a giant beast. Meanwhile, Alphonse gets Gluttony to take him to Father, who is apparently in Central, and Wrath gets leverage over Mustang by transferring his men to various military command headquarters and assigning Hawkeye as his personal assistant, effectively making her his hostage. (Source: Wikipedia)
