Timeless, darling, I hate to do this... but it's highly unlikely that your character knows Ciaran. He is a first year teacher and hasn't been back to the school since his graduation which was before the war. >.> Would it bother you terribly to adjust your post or at least tell me how they know each other, because he's gonna get all Auror-paranoid about someone he doesn't know being so familiar with him. xD
