Ah . . . Roy is fine. Brigadier General Mustang if you really insist on a title.

[ he is definitely not nobility, or an aristocrat, or anything resembling a lord. still: ]

I would be willing to try, if he showed up again, but it's more a problem of figuring out how to contact him, rather than actually doing it. He was little more than a kid. He couldn't have been older than twenty.

[ if that. ]

I don't think he'll have much issue in talking with us, if we manage to find him again.
