"Expelliarmus!"
Harry's body became instantly rigid and immobile, and he felt himself fall back against the tower wall, propped like an unsteady statue, unable to move or speak. He could not understand how it had happened-- Expelliarmus was not a Freezing Charm--
Dumbledore must be trying to protect me! Harry thought quickly, feeling a rush of understanding and relief.
Draco burst into the room. He looked around, as if trying to locate something. "Where is he?" He asked quietly.
Dumbledore pointed a shriveled hand at Harry. "He's right there, under the invisibility cloak."
Harry's eyes would have widened in shock if he could move, but he could only watch as Draco turned and yelled out the door, "He's in here! He's in here!"
Draco turned back to Harry and put his hands out to feel where he was. When his fingertips made contact with Harry's chest, he grabbed the invisibility cloak and yanked it off. A smirk widened on his face. "Lets take him to Voldemorts secret hideout. Ron, lead the way."
Harry looked behind Draco sharply as he just noticed Ron Weasly had entered the room, wearing heavy black robes that didn't suit him and carrying a white mask.
Inside harry's mind, he was screaming. NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!
