Okay, so Kate's guess was correct. They were heading down to the Chamber to find three teeth from a basilisk. Hopefully they'd find them soon, because the Chamber wasn't exactly Kate's favorite place to be. If she was being honest with herself, she did think about going back. She had to trust two of her professors, though. With one in front of them and one in the back, not too much could go wrong, right?

That was the hope. On that note, Kate followed the first professor down into the Chamber.
