Shane looked around. He didn't see anything they could use as bait except the owl, and that just wasn't going to happen. There weren't even any classrooms in this hallway, there was just...the armory.
"The armory," he said, already moving toward it. He opened the door and found it blessedly empty of house elves. It was full of statues, though, just like he remembered. There were weapons as well, of course, but the idea of killing a house elf-killing anything-turned Shane's stomach to a block of ice. He'd been responsible for enough deaths.
He looked at William. "We have to be the bait," he said. "We lure them in and then use the statues to keep them there."
