Ed and Al hear of a blind alchemist named Judau who had supposedly performed a successful human transmutation. Meeting up with him, Judau reveals to Ed that a young girl named Rosalie was resurrected through alchemy, with his eyes paid for in equivalent exchange. However, the Madam refuses to teach Ed about the techniques used. Rosalie leads Al to a room with a little girl's shriveled corpse inside. She reveals this as the result of the real Rosalie's transmutation, whilst she herself is a girl named Amy who was adopted due to her similar appearance. As Ed arrives on the scene, the Madam tells him that her late husband kept the truth about the transmutation's failure from Judau, who truly wanted to resurrect Rosalie. Ed and Al then leave, carrying this knowledge with them as well.
