Episode 49: The Other Side of the Gate (2003 series)

Führer King Bradley arrives home to give his son Selim a birthday gift for his tenth birthday, which is a toy train. In another location, Envy reveals to Alphonse Elric that they are at his master's place and unlike the other Homunculi he has no intention of becoming human which is why he isn't fooled by his master's false promise. Envy leaves the room stating the 7,000 soldiers killed in Reole and the Ishvalans killed at Ishval are within the Philosopher's Stone, which makes Al wish he had died when he had been given the chance several times earlier. Meanwhile Edward Elric meets with Russell and Fletcher Tringham in an abandoned church that has a secret entrance that was logged into their father's journal. Russell explains the story that when their father came to Central City years ago to learn how to refine the red water he wound up working at the Laboratory 5, until one day when a certain alchemist showed Nash the real secret lab to teach him how to perfectly refine red water into a Philosopher's Stone. Recognizing that Lab. 5 was a front, Ed transmutes and then heads off through the secret entrance alone, with the promise to Russell that he will not create the stone. Following the path, Ed discovers an ancient city hidden beneath Central and remembering what Russell told him from the journal, Ed realizes that when someone did create the Philosopher's Stone 400 years ago the city was hidden underground to hide the knowledge of the human sacrifices. Ed realizes that his father was likely involved.

At their hideout, Dante is making it clear that Rosé will be her next host. However the problems they are having is Gluttony is lonely without Lust and that Wrath wants to use the stone to revive Sloth, which forces Envy to beat him up. Back at Central Command, Izumi Curtis is having difficulty battling Frank Archer due to his automail armaments being too strong for her transmutations as his backup arrives. Archer offers for her to join him, stating the State Military will eventually take over the land, something that Izumi flatly refuses. Izumi can barely make another shield before her conditions affects her. As Archer is ready to finish her off, Maria Ross and Denny Brosh arrive with their own backup to support Izumi. Ed arrives at Dante's headquarters and notices Rosé dancing. In Resembool, Sheska realizes and mentions to Winry that the actions of the Homunculi have in fact been intended to keep reckless people from dangerously creating the Philosopher's Stone and using it for themselves, which is the origin of the rumors of how the Stone was too dangerous to complete. After dancing with Rosé, Ed discovers that Lyra brought her there when she shows up with Rosé's baby.

Dante tries to pretend to be Lyra, and cover up the details on how she knew about this place. However, Ed is now aware that she is Dante, explaining the mistakes she made in her faked death: the transmutation circle which seals up the Homunculus was found at her house, along with the bones from the human Greed was modeled after so Greed couldn't do anything. Furthermore, Ed is now aware the Philosopher's Stone can be used to transfer souls between a human body which allows a person to live on for centuries, and is the reason why Dante killed the real Lyra whose soul was in Dante's old body. To prove his point Ed summons a transmuted spear, which Dante quickly destroys, and verifies that Dante has seen The Gate which allows her to transmute without a circle, something the real Lyra is incapable of. Dante confirms that the residents in the ancient city had been killed for the purpose to create the stone, though Hohenheim was the one to make the stone for her. Dante reveals her mission is to protect humanity from using the stone foolishly which is why they spread the rumors about the stone and also steal it if someone does complete the Philosopher's Stone. Dante reveals that she will make love to Ed once she takes over Rosé's body. Gluttony then comes in looking for Lust. After Ed convinces him that Wrath killed Lust, Gluttony leaves and Ed attacks Dante. Dodging her attack, he cuts part of Dante's dress with his automail sword, confirming the mutilated skin on Lyra's body is a sign that Dante cannot transfer her soul between bodies forever.

Dante reveals that Equivalent Exchange is a lie, stating that not everyone gets the same thing from what is lost, and mentions that while numerous people apply to the State Alchemy exams, only few pass. Using her transmuted Stone snake to grab Rosé's baby by stating not everyone is equal, Dante continues to lecture Ed and Ed ignores her and saves the baby. However a transmutation circle on the baby sends Ed to the other side of The Gate in the parallel world. Ed wakes up and finds himself in another body and discovers his father. Once he confirms that it is the Ed from his world, Hohenheim tells him to run, as it is the day the zeppelins are dropping bombs in London during World War I.
