Episode 47: Sealing the Homunculus (2003 series)

Sloth works on convincing Alphonse Elric to come with her, by acting the way Trisha Elric used to act to him, while on the street Wrath as he is laying down recalls his memories in the gate and believes that Sloth, not Izumi Curtis is his real mother. Before leaving, Sloth strangles Shou Tucker by creating a sphere of water around his head since Tucker's role in this is over, as Tucker tries to convince Al to try again at resurrecting his daughter. Edward Elric transmutes nearby metallic material into a replacement hand for his automail arm just as Sloth and Al arrive. Ed tries to convince Al that despite her appearance, Sloth is an imitation of their mother, but Al is still taken in by this. When Tucker arrives, and seeing the portion of Al's armor that is missing, Ed quickly realizes that Tucker tricked Al. Ed begins the battle by transmuting his automail arm into a machine gun, forcing Tucker to retreat and Sloth to turn her body into water, but Al gets in the way. Ed then runs and just as Sloth encases him with water, Ed reveals his trap, which is the same type of Transmutation Circle used against Greed in Dante's house to seal away the Homunculus which Lust created for him. Ed then throws the locket at Lust, which she bats away stating she did not do it to get ahold of that.

Ed then reveals he has his mothers remains when he desecrated her grave and infuses the small case with the remains into Sloth's body, much to Al's horror. Sloth wants Lust to state why she betrayed their master, and Lust admits that it was due to her memories, which she believes are created from the strong emotions of the one who performed the human transmutation. Al then betrays Ed by grabbing the case and throwing it out the window not wishing to use their mother's remains like this. As a recovering Sloth is vomiting a few Red Stones, Al explains that even if they did create her, they cannot destroy her. Lust volunteers for their task, and as Ed heads after the case, he finds that Wrath had found it first. Realizing what the Elrics are doing, Wrath is determined to protect his mother. Ed explains that Sloth is not his mother, nor his, but an abomination. Wrath infuses the case into his body and knocks Ed back into the building. Inside, Wrath transmutes numerous guns to his left arm and fires them at Lust. Sloth uses the chance to turn into water and enter the hole in Al's armor to take control. Destroying the guns on Wrath's arm, Lust has Ed purse Sloth, while she deals with Wrath. Lust admits that even though Wrath doesn't have any remains that can be used against him, she can still kill him once the Red Stones in his body are used up. As Wrath can only try to dodge Lust's attacks, when he is knocked down, Wrath notices the locket with Lust's human remains that Ed dropped earlier. Reminding Lust he can use alchemy, and with it clear that she is in the transmutation circle, Wrath uses the locket to paralyze Lust before she can flee and then activates the circle. Ed catches up with Sloth and can't fight Al to avoid any alchemical reactions as he tries again to explain to Al this person isn't their mother. Ed starts drawing something on two different identical tables as he dodges Al's attacks and Sloth thinks he is trying to use a transmutation circle against his brother instead. However, Ed's plan is to draw half a circle on each so he and Al can unite them together to turn both Al and Sloth's bodies into ice just as she realizes it. As Lust begins vomiting Red Stones, Wrath makes her realize her only reason to become human is to die. Wrath then transmutes the gun on his arm into a sword and kills Lust. He then questions his own desire to become human, and noticing Tucker, Wrath tries to ask him, only for Tucker to retreat out of fear.

Ed apologizes to Al for what he did, but Al makes his own apology for his own foolishness. As Sloth begins to break free she admits she first saw them that night when they performed Human Transmutation flashing back in the past. Dante was in Resembool that night, and knew that since the boys were Hohenheim's sons this would happen. Giving her some Red Stones, Dante took the bodied corpse that was Sloth with her to her house. After eating enough Red Stones to attain her form, Dante convinced Sloth who was dominated by Trisha Elric's memories she make her human. Dante put Sloth under Pride's command to serve in the military under the vacant name that Pride previously used to start the Ishval Civil War to avoid suspicion. In the present, Ed realizes Sloth is vibrating her cells to generate heat and thaw herself out. After breaking free and separating from Al's armor, Sloth admits that as Lust said, she does have Trishas memories due to the Elrics' strong emotions when they created her. Sloth wishes to kill them so she can be free from her memories.

As Sloth continues the fight to where none of Ed's attacks are working, when Wrath shows up, a distracted Sloth is stabbed by Ed's automail sword which he transmuted into sodium so it can react with Sloth's watery body and cause it to explode. Sloth is still alive, and Wrath determined to protect her, decides to fuse with her. However, this proves to be his ultimate mistake, as Wrath had absorbed Trisha's remains into his body earlier. With Sloth no longer able to move, Ed decides to use a similar method when he previously transmuted Greed's body. Ed's transmutation turns Sloth's body into ethanol, and Ed orders Wrath to get away from her as she will vaporize. The episodes ends as Winry Rockbell is viewing the battle.
