She did not know every person on this battlefield. She did not know every man and woman she had vowed to kill when Ron and she had realised Harry was not by her side. What she did know was that their side was tending to the dead while her future victims were hiding in a forest never less forbidden. So this stranger, taller than any of them, darker than the night... they did not belong in front of her. They were not supposed to look down upon her with fondness. They were not supposed to smile at every twitch on her wand-arm.
