Dean stared at his class schedule, trying to keep his panic to a minimum. When he'd decided to go to school for engineering he hadn't really thought about the hard-as-hell classes that he would need to take as a result.
His mornings were filled with Chemistry, Physics and Calculus. Dean was okay with the Chemistry and Physics, but there was no way in hell he'd be able to pull off Calculus. How he'd even managed to get into Calculus was beyond him, he'd struggled with Geometry in high school.
"You better not be plotting something. You have that look on your face." A gravelly voice came from the doorway, making him lose his train of thought.
"Do you, like, follow me around or something? You're like a demented version of a guardian angel."
"Considering this is my floor, and my responsibility, and you are you... I figured it's best to keep an eye out for your dumbass shenanigans. Plus, part of my job is to make sure the lounge is clean, and everything is in here in one piece."
"Dude. What's your problem?"
Cas ignored Dean, and sat next to him on the couch, staring at the paper in his hands. "Calc with Professor Brewer, huh? That's gonna suck. He was the professor from hell."
Dean eyed him suspiciously, "Haven't you ever heard of personal space?"
Cas just laughed, "I'm a theater major. There's no such thing."
There was a brief moment of silence as Dean processed what he was just told. "Wait, why would a theater major take Calculus?"
"A math course is required as a Gen. Ed., and I happen to enjoy Calculus. Two birds. One stone."
"How could anyone-" Dean's eyes grew large. "You wouldn't happen to have your old notes and assignments still, would you?"
"Of course I do." Cas scoffed, shaking his head. "Freshmen." He got off the couch, and headed out the door.
"Wait!"
Dean heard Cas shout from the down hallway, "Don't make a mess in there."
