"I am glad to see that my lab is still intact, at the very least. Upstead! Did I not instruct you to consume the fever fudge so you could test your potion? What in Merlin's pinstriped pajamas are you waiting for?" He glared at the boy.

He waited impatiently for the students who were in trouble to enter the room.
