Episode 3: Mother (2003 series)

Synopsis
Ed and Al revisit childhood memories, recalling the constant and unconditional love of their mother -- and the horrors that began when she died.

Trivia

 * When the Elric brothers are sparring at the end of the episode, Al falls in water and gets back out without any damage to his Blood Seal. This is inconsistent as through most of the part of the series he doesn't go in water due to the fear of his Seal being damaged. However, since this was his very first time sparring in that body, it could be that at that point, he was simply unaware of the peril water actually now posed to him.
