FIVE LICKED THE BLOOD OFF HIS FINGERS, He had gone completely crazed, his sanity left him the moment you also left — it was after finding out he was a death eater. He loved you and held you to his heart dearly. Seeing you with anyone else made him feel sick to his stomach and fills him with immense rage.

Five stalked you every now and then, nobody knew he was behind all the disappearances, people saw him as the quiet but cunning Slytherin kid. Never a murderous insane obsessed lunatic.
