One morning Prussia was being very loud

Winry told him to shut his whore mouth.

It was the start of a beautiful relationship.

Winry finds Prussia to be a very funny guy, and very much like Edward she has a tendency to be violent towards him. They've talked on a number of occasions and most of it has either been Prussia pissing her off, or her taunting him, but they've had some serious conversations. Despite herself she can't help but like him regardless.

Prussia lost his arm against a Kishin, and so Winry will be building him some automail and helping him through physical therapy.

-His automail mechanic
-No he isn't attractive shut up
