    Harry had no idea how it happened, but somehow the four of them made it back to the Slytherin common room without running into any teachers. Pansy had kept her word, and the prefects were still trying to sort everyone out when they slipped in. Hermione had cast a few quick charms to tidy up their appearances, followed by the Leviosa charm just in case Professor Snape decided to check her wand. Harry followed her example.
