Selina approached the door for the Muggle Studies room and moved to open the door. It was locked. She turned her head around to check if anyone was pulling a prank on her. Nope, no one was there. She crossed her arms and waited for someone to come by and help her. After a few minutes of waiting shebknocked on the door, "Hello? Selina Skylar, I'm in Gryffindor. We have Muggle Studies today right?". Where was her Professor?
