Hogwarts Subjects [1/10]: Potions

“There will be no foolish wand-waving or silly incantations in this class. As such, I don’t expect many of you to appreciate the subtle science and exact art that is potion-making. However, for those select few who possess the predisposition, I can teach you how to bewitch the mind and ensnare the senses. I can tell you how to bottle fame, brew glory, and even put a stopper in death.”

Then he goes all red ‘cause Dean just saw the whole thing. Like, could you just imagine how cute it’d look.
