Roy nodded his assent. While he was generally an egotistical asshole he could accept the fact that in a healing house, the doctors were in charge. He'd spent too much time on a battlefield to understand that in triage you were part of the solution, or you got the fuck out and let them do their job before you became part of the problem.
Sure, he could step back and let the Doctor take charge here.
Mustang folded his arms across his chest and eyed the boy, hiding the clench of his fists against his chest when Ed ran his mouth. Like usual, the kid didn't even pretend to show respect, but given the circumstances Roy was willing to be more forgiving. Rather than be offended, the Colonel offered a faint smile.
"At least we can be assured you're not going to die, Fullmetal, you're capable of running your mouth still. Can't speak about the state of your brain though." Given what he was saying made no sense as far as timelines went. Of course, Roy had become aware of the events surrounding Lab 5 only after Maes Hughes had died, but both of those things were months past.
Hughes. Ed wouldn't know about that then, judging by the information spilling from the kid. He was from some time before Roy himself.
Mustang glared, angry that Ed had forced thoughts of Roy's dead friend to the forefront of his mind.
"Don't think too hard, Edward, you'll hurt yourself trying." He said sarcastically. "Why don't you check his brain for swelling, Doctor Jones? He's speaking a lot of nonsense."
