Episode Notes

 * The song used the moment Riza starts crying over Roy is entitled Wakare no Kyoku (別れの曲, music for parting), and is actually taken from Étude op. 10, No. 3 by Frédéric Chopin.
 * The part of Mustang drawing a transmutation circle on his hand with his own blood and using it to burn Pride (The Führer - King Bradley) to death is similar to how he killed Lust in the manga and the 2009 anime.
 * Notably the chapter this plotline originated from Chapter 39: Complications at Central was at the time the latest manga chapter released in Japan which was released not long before this episode's original airing.
 * In the United States, this episode aired with a disclaimer, warning viewers about the content of the episode.
 * This episode, more importantly, it's ending, would be the foundation for the Fullmetal Alchemist Film, Fullmetal Alchemist the Movie: Conqueror of Shamballa which was BONES' own original ending to the 2003 anime.
