Fullmetal Alchemist Season 1 Episode 47

Sealing the Homunculus

Ed discovers Sloth and Al at Tucker's research lab. He tries to convince Al that the Homunculus is not their mother, and not to be trusted, but Al is pretty sure that it'll be fine. So Ed has to do things his way. He reveals the pieces of his mother's corpse that he dug up in Rizenbul, stunning Sloth, and giving him a chance to seal her forever. Lust had drawn a sealing transmutation circle with her claws, so it could not be destroyed, and Ed lured Sloth into it. The deal was almost done, when Al in his infinite wisdom decided that he was going to save the homunculus, so he threw the box containing a piece of his mother out the window, thus freeing Sloth. Lust held her at bay while Ed went to get the box, but Wrath was waiting outside, and decided to absorb the box into himself so Ed couldn't get it back. More and more it became clear that the brothers would not win this battle so easily, especially with Al helping out the Homunculus. Sloth freed herself from the circle, and while Ed chased Sloth, who was now controlling Al's body from the inside, Wrath and Lust squared off. Lust is easily destroyed though, as Wrath found her locket and used it to stop her on the transmutation circle. Wrath killed Lust and headed off to find Sloth. Fortunately for the brothers, who were not in great shape at this point, Wrath was a bit inexperienced, and foolishly merged himself with Sloth. Having the box inside of him, this stopped them both and gave Ed his chance to destroy his creation, Sloth, once and for all.
