A dad's goodbye [Reverse Dad AU FMA]

This oneshot is based on the "Reverse Dad AU", created by dailymaeshughes on Tumblr.

In this AU, Roy and Maes switch places. Colonel Maes Hughes is a hardworking soldier, also known as the "Glacier Alchemist", who wants to be fuhrer. His team, including First Lieutenant Gracia Munoz, support him as best as they can. But Maes has other support too. His best friend, Lieutenant Colonel Roy Mustang is always there, to tell the Colonel about his family: his beautiful wife Riza, his two adopted sons Ed and Al and his little dogs.
But then there's the day, where Roy can't talk about his family anymore. Knowing too much, the homunculi decide, he had to die. And that's how we lost the greatest dad we've ever known.
