Episode Notes

 * This episode is adapted from content in Chapter 19: I'll Do It for You Guys!, Chapter 20: The Terror of the Teacher, Chapter 21: The Brothers' Secret, Chapter 22: The Masked Man, Chapter 23: Knocking on Heaven's Door and Chapter 25: Master and Apprentice.
 * The symbol that appears in the background of this episode's title card is the Flamel.
 * The scenes involving Mason's role on Yock Island are not shown in this episode.
 * In this episode, the path Edward takes to understanding "One is all, all is one" is different from that in the corresponding manga chapters. With the exclusion of Mason and his involvement in their training, Edward learns by first eating ants to survive, rather than realizing that they will eat him if he dies.
 * Izumi's encounter with the children of Dublith is omitted and her discovery of the Edward's ability is altered - instead of witnessing his circle-less transmutation during an exhibition of the boys' improved skills, she attacks Ed and forces him to transmute his automail arm to defend himself.
 * This episode displays Izumi's attempted Human Transmutation from a wider angle from the manga, revealing that her circle had been of an identical design to that which Ed had created, albeit using different runes in places.
