The full moon came and went, when Lupin awoke from his slumber, there was a certain buzz in the school… a werewolf had been sighted. You had been sighted- transformed in the full moon. When Remus reached the hospital wing, he saw your bed, surrounded by the teachers and headmaster, Dumbledore and McGonagall were comforting you as you shivered in fear.

What you didn’t know, is that Lupin was your father, and, apparently, his werewolf genes had passed down to you, his child. After you were conceived you mother had left him without telling her where you’d be.
