Hal laughs a startled laugh. "Thou--thou hast been--in thy time, Percy, thou hast been a rebel. A very valiant rebel--"

Oh, this is a conversation he never thought to have. He puts his hand on Percy's shoulder and finds that he can't stop laughing. Which is most unseemly--most unkingly--they are singing Non nobis--non nobis, Domine, but to thy name give the glory--

He rests his forehead on Harry's armored shoulder and tries to smother the helpless laughter.
