Standing there, facing Michael in the cemetery, Lucifer's breath was stolen by a strange stutter in his chest. Seeing his elder brother for the first time in so long... He realized he had missed Michael. He had missed the touch of his loving grace, the sight of his wings-which Lucifer now saw, all six flared in a display of power. He felt a rush of sorrow when he realized that Michael had come here fully prepared to battle, prepared to kill him, his little brother.

Lucifer thought, for a mere second, what he could have had if he hadn't left Heaven, left Michael, left home.

And, in that mere second... Lucifer felt regret.
