"Aren't you coming?" Harry asked, as he neared the carriage. "I forgot my scarf, you two go on, I'll catch you in a bit," Hermione lied as she hopped back on the train. She sneaked down the carriages until she reached the door of the carriage where Draco stood. She peered through the window. There, Hermione could see, Draco brandishing a key, and it did not look like any ordinary key. It seemed like an old fashioned one, it was brass and quite big, Hermione could only guess where that key would fit, which confirmed her suspicions of a vanishing cabinet being at Hogwarts. Was he going to escape on the first day back? Hermione wondered.
