Cas walked up to his little sister and spun her around before walking her to the corner, "you can stand there until you are ready to talk to me properly." He stood back, making sure she wasn’t going to instantly whirl out of the corner before he walked over to her bed and sat on it. He wasn’t planning on leaving her there for long, just enough to give her a chance to rethink her attitude and calm down somewhat. He had plenty of experience staring at corners, enough to know it was a good way of draining out anger, it was hard to remain angry when staring at the corner of a room.
