This fairytale ends like the usual one, the prince marries the well, peasant turned into princess, and they all live happily ever after.
With a few changes.
Alphonse the cat really turned out to be Edward's long lost brother, turned into a kitten when a evil witch snuck into the castle when he was a baby - he returned to the palace, got kissed on the head by the seventeenth princess of Xing by a very complicated means of visiting, a .kitty fight and a number of other events, and POOF, INSTANT LONG LOST BROTHER.
As for Greedila and Envila?
They lived the rest of their lives with new jobs... as scarecrows.
It also turns out that Prince Edward had a fake arm and leg, due from a scientific accident after his mother died. Unfortunatley, the creator of the arm and leg wasn't... that good. And he died anyway.
The now-Princess-soon-to-be-Queen Winry soon found this out! So, using her wonderful mechanical skills she created him a metal arm and leg and he used them, oh yes he did.
And Winry found that gold, gem-encrusted wrench very useful indeed.
The End.
