The Doctor straightened his bolo tie and watched the door with a thoughtful expression as he decided how exactly to enter the class room. After a few seconds thought, he kicked the door open and strode in, watching from the corner of his eye as a class of sixty children, all aged between eleven and twelve, stopped chattering and watched him with fascination.<br/><br/>The room was exactly how they would picture it to look. Skeletons of dangerous mythical creatures hung from the ceiling, tanks with various deadly creatures lined the walls, magical portraits hung on the walls and various bits of magical equipment lay in various places. There was a desk at the front of the room with two chairs behind it, lined with dark blue leather, the same color as the TARDIS.<br/><br/>The Doctor hovered at the front of the class room, unsure of exactly where to sit, before he finally made a decision of what to do.<br/><br/>"Raise your hands if you're in Slytherin," he called as he turned to the crowd of kids. A murmur of confusion passed through them, before fifteen children raised their hands.<br/><br/>"Keep them raised if your name is Draco Malfoy," he said and watched as fourteen hands dropped, leaving a young boy with bleach blonde hair and a cruel expression waving his arm in the air, staring at him with annoyance and confusion.<br/><br/>"Fantastic!" The Doctor spoke before putting his hands in his trouser pockets and pacing on the spot. "My name is the Doctor, ignore the name Professor Smith, that's a boring name that you can call my wife. I'm hear to teach you about defending yourself against the Dark Arts. Together we will make a mysterious journey through this magical world and learn just what dark arts are and how we can defend ourselves against them."<br/><br/>"Sir, can I put down my hand now?" Draco asked, unable to keep the spite out of his voice.<br/><br/>"No you may not Draco," the Doctor said before hoping into one of the chairs and putting his feet up on the desk. "No you may not."
