From inside Gluttony's stomach to the Truth portal, it's quite a ride. Ed, Lin, and Envy manage to find their way out, eventually, not before Ed actually figuring out what happened to Cselkcess (Xerxes, it seems). Quite a revealing episode, if I also think about the origin story of Wrath/King Bradley, and I really wonder how will Roy Mustang continue his collaboration with the Army. And why is he still alive.
