Full Metal Alchemist Season 4 Episode 12 Death

On the other side of the Gate, Ed finds himself in a world that, while much like his own, has some major differences. There he finds his father, who finally reveals the truth about his past actions---and of alchemy in general.

There is much going on in Ed's absence, however; in the underground city, Dante puts her plans for Al into play and turns Gluttony into a horrific creature while Mustang puts his own plans for the Fuhrer into action.
