Time flies in this episode, covering a lot of backstory. A basic timeline goes like this:
1905: Ed age 6, Al age 5, perform their first act of alchemy to create a dolly for their friend Winry. Winry freaks out,
crying and screaming. Tricia Elric, Ed and Al's mother, is surprised that her young sons learned how to do alchemy just from
reading books she thought were above their level of understanding, but encourages them to do more. Alchemy reminds her of
the missing man of the house.
1909: Tricia has been ill for years. Ed is angry at his father, thinking Tricia has gotten sick due to her husband being
away. He writes letters to all of the old correspondance he finds in his fathers office, hoping one of them knows where Elric
is. Tricia dies. Ed convinces Al that they should try to bring her back to life.
1910: After a year of training under a mysterious woman, Ed and Al attempt to revive their mother, with horrible consequences.
Ed's left leg below the knee is absorbed by the Array. Al is completely taken by the Array, but Ed sacrifices his right arm
in order to bind Al's soul to a large suit of armor. Roy Mustang had responded to one of Ed's letters about his father, and
sees the aftermath of the forbidden alchemy. Roy speaks about his fascination in Ed's skill and power at the age of 11, and
about National Alchemists. Ed then gets Automail replacements in his determination to travel to Central City and become a
National Alchemist. Ed and Al vow to return each other's bodies to their original forms.
In this episode we learn:
