Triwizard tournament (2)

You are Draco Malfoy’s older brother, Lysander Malfoy.
You are currently taking part in the third task of the Triwizard Tournament as Hogwarts’ representative, alongside Cedric Diggory from Hufflepuff and Harry Potter from Gryffindor: the Maze Task, where the maze contains various creatures and anti-gravity mist. You’ve managed to navigate those obstacles fairly easily, but your goal here isn’t to win, but to save the friend you consider your equal (Cedric) and the boy you respect for his courage (Harry). You’ve fitted them with trackers, so you must follow where they’re heading. And there they are, in the middle of the maze, a cup lies between them; Cedric and Harry move to grab it, and you quickly grab the cup too, because it turns out the cup is... a Portkey. The three of you are transported to the graveyard; with you further away from them, you watch what is about to happen in the darkness, calmly hiding behind a large statue so as not to be seen. And there you see him, Peter Pettigrew, walking into view carrying Baby Voldemort in his arms. Voldemort says, “Kill the spare,” and Peter raises his wand to cast the ‘Avada Kedavra’ spell. What will you do?
