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 Roy 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.
 * In North America, this episode aired with an advisory, warning viewers about the content of the episode.
