It's Time to Rest
Gracia doesn't ask how Roy recovers his sight or how his hands heal after a man who introduces himself as Doctor Marcoh visits him on the third day after the battle that threw the country upside down. She will hear about it somewhere safer than a hospital room. What she does is insist that Roy stays with her and Elicia once he is discharged later that day. Roy tries to refuse, but his entire team sides with Gracia. Riza Hawkeye is terrifying even from a hospital bed with her neck bandaged (Gracia hasn't asked about that yet, either).
By the time Roy steps into the house, Gracia has returned the picture of his and Maes' graduation from the Academy to the mantelpiece, and the one in which he holds baby Elicia is back at the hallway with the collection of pictures of Elicia that Maes gathered there over the years.
Roy leaves his bag at the guest room as instructed, insists that he doesn't need rest now that he is healed (Gracia still doesn't ask, certain that he isn't ready to talk about it) and barely picks at his dinner. He doesn't even seem to notice that he is doing it, and Gracia wonders how long it has been since he ate a full, healthy meal.
The first morning, Gracia finds Roy reading on the couch in the living room when she wakes up, and the same happens on the second morning. The circles under his eyes haven't diminished, and Gracia is certain that he is barely sleeping, if at all.
Deciding that enough is enough, Gracia chooses to go straight for the big guns. She tells Elicia that Uncle Roy has nightmares, and he could use company just like Elicia does when she has bad dreams of her own. Not even a stubborn bastard like Roy Mustang can resist a determined and well meaning three year old, and the resigned look Roy gives Gracia as he follows Elicia out of the living room that night tells her as much.
The next morning Gracia doesn't find Roy reading, and the dark circles seem to have diminished somewhat at breakfast.
