You're in the same year as Harry, Ron, Hermione. It's 5th year. You have spend the past years at Beauxbatons. You didn't got expelled but just didn't like it there. You already got sorted into Gryffindor this morning in private. Now you're walking towards the Great Hall. Someone blocks your path. It's a few boys, and you see that they're in Slytherin. They look up at you with intrigued smiles. "What do we have here?" One of them says. He looks like the leader.
