Disclaimer: I don't own Roy, okay?
Whoo! I knew I had to make a drabble of this when I found out!
Roy one day was quite bored, so he decided to look up random words in the dictionary.
He thought about the Homunculus that were always chasing the Elric's so he wondered what the dictionary had to say about them.
Homunculus: a diminutive human being.
"Hmm… I never knew that Ed was a Homunculus himself…"
I hope I was the first to figure that out! Haha...
