Every time Ed and Roy talked; Ed took a mental note of it. He would figure out who won, who lost or when it was a tie. He would then record this in a notebook he kept.

The notebook wasn't special or unique in any way. It was small and black. Simple. Yet, had every single battle outcome between Roy and Ed; separated in columns. Ed-win, Ed-lose, Roy-win, Roy-lose and tie.

Ed was the scorekeeper and he never missed a score. Or a battle's outcome for that matter never forgot to fill the book in either.

They were enemies. Then, Roy decided to change that and Edward stopped keeping score.

After Roy changed the boundaries between them Ed trashed the book the next morning.
