"You have ninety minutes. You may begin." Castiel told his students as they began their midterm. He made his way back to his desk to start work on some grading from other classes but the words just kept blurring in front of him. He took off his glasses and rubbed his eyes. Ever since the Winchesters had moved in with him two weeks ago, Castiel's life had been filled with too little sleep, grueling training and too much sass from Dean Winchester.

Every morning began with Castiel and Sam hitting the college gym at an ungodly hour and then jogging back to the house. Sam insisted that physical fitness was one of the key parts of being a good hunter. After day two of one of Sam's workouts that left Castiel exhausted and sore, he asked why his brother didn't take part in the same training. Sam huffed and rolled his eyes, stating that Dean had his own ways of staying fit.

Castiel found out quickly what Dean did to keep fit. He was just thankful the town didn't have an all female college. At least he didn't think he would have to worry about Dean trying to hit on the two most important women in his life since Charlie was gay and Cindy being old enough to be his mother, but he was wrong on both counts.

After Castiel gave the weak lie about the Winchesters staying with him which consisted of helping Sam with his dissertation, that Charlie clearly did not believe, but stayed quiet anyways, quickly became best friends with Dean. While Dean was snarky and arrogant toward Castiel, he was all smiles and laughs with Charlie as they discussed pop culture and their shared love of Scarlett Johansson.

Castiel didn't think the betrayal could go any deeper until Dean managed worm his way into Cindy's good graces. He flirted outrageously with the older woman who would regularly give him free pie.

Cindy never gave Castiel free pie.

"Are you going to put up with that Dan?" Castiel asked Cindy's husband as he wiped down the long counter that patrons would use if dining alone. Castiel sat slumped on one of the stools, running a hand idly over the scarred wood. He would occasional glare over at the booth that held Dean, Sam, Charlie and now Cindy who had taken over Castiel's vacated seat.

"Son, I've seen you flirt worse with my wife and I didn't kick your ass. I can't help it if she has a thing with men with pretty eyes. Are you jealous, Cas?" Daniel asked, a hint of laughter in his voice.

Castiel frowned down at the counter. "No, sorry I'm just cranky with midterms coming up and all."

Daniel put down his rag and reached across the counter to pat Castiel on the shoulder. "Before you know it, midterms will be over and you'll have a bit of a breather before finals. One weekend, I'll take some time off and we'll go do something."

Castiel smiled. "I'd like that."

A little later they were leaving the diner, Dean surprised Castiel by putting his arm around his shoulders as they walked back to his house.

"Dude, Cindy makes the best pie. I'd marry her pie if I could."

Sam seeing Castiel's face, laughed. "Dean has a long standing love affair with pie. You'll get use to it."

Castiel shook his head to clear his thoughts and tried to concentrate on his grading. He stared down at one of the papers he had been trying to grade for the past half hour, but the words just started bleeding together causing Castiel to blink rapidly. Gradually, his blinks became much slower until he decided to just rest his eyes for a moment.

"Dr. Milton? Umm, are you okay?" A hand hesitantly shook his shoulder as Castiel blinked blearily up at the concerned blue eyes of one of his students. Castiel tried to discreetly rub the sleep from his eyes and looked around the deserted classroom, a neat pile of blue test booklets sat in front of him. He stifled a groan when he realized that he had fallen asleep while administering the test.

He straightened up, giving his student a sheepish smile. "I'm fine. Thank you, Tyler." Castiel murmured to the student.

Tyler clapped Castiel's shoulder before setting down his completed test on the desk and hiking the strap of his backpack up over his shoulder. "No problem, Dr. Milton."

He started to walk away and then hesitated at the door. Tyler started to turn around and then stop only to repeat the movement again.

Despite being bone tired, Castiel bit back an amused smile at his favorite student's antics.

"Tyler, was there anything else?" The young man turned back around and walked to the closer to Castiel.

"It's nothing, just curiosity. I noticed you've been at the gym every morning the past two weeks with that tall guy that I've been seeing around campus. I mean, if you needed a work out buddy, I'm always there at that time, I could…"

Castiel didn't know whether to laugh or groan at his over eager student. Normally he didn't share his personal life with his students, but lack of sleep made his tongue loose. "Sam worries about my physical fitness and likes to torture me with early morning routines, but his heart is in the right place. He'll eventually tire of my complaining." Castiel yawned as he ran his fingers through his hair, eternally thankful it was the last class of the day.

"Sam? Is he your…?" Tyler trailed off.

"Is he my…?" Castiel asked, too weary to interpret what his student was trying to ask.

"You know, your boyfriend?" Tyler asked, a blush gracing his round face.

Under normal circumstances, Castiel would have firmly but kindly informed Tyler it wasn't any of his business however the unexpectedness of the question had him responding. "No, he's just a friend staying with me for a little while."

Tyler's face broke out into a sunny smile. "Oh…good. Well, see you around, Dr. Milton!"

Tyler almost collided with Charlie as he left the classroom, giving a cheerful greeting to Charlie before making his way out into the hallway. Charlie watched him go with a bemused look on her face.

"Oh Cas, the poor boy has it bad."

"Has what bad?" Castiel asked distractedly as he gathered up the tests, shoving them in his satchel. His body protested as he stood up, muscles still achy from Sam's early morning routine. Castiel thought that Sam was the nice one of the brothers, but Castiel was finding he'd rather put up with Dean's snarky and arrogant attitude during their weaponry lessons than Sam's brutal workout regime.

"He has the hots for you." Charlie leaned against the desk, smiling teasingly.

"Who?"

"Oh my god, Cas! Tyler, the kid that just left your classroom. The one that I know for a fact finished his test first, but stuck around until everybody left. The one that always looks at you like you're his every wet dream come true. That Tyler."

Castiel looked at Charlie blankly for a moment before he scowled. "No he doesn't. He's just enthusiastic and he wants the position as my TA next term. Besides, he wouldn't be interested in me for the simple fact that I'm his professor and too old for him." Castiel grumbled and then paused in the act of straightening up his desk to glare again at Charlie. "Really Charlie, 'wet dream come true'? Was that really necessary?"

"Are you kidding me? Older means experience. Besides, you have that whole serious hot professor thing going on. He probably wants you to discipline him." Charlie wiggled her eyebrows.

"I really should fire you." Castiel said dejectedly as he put his bag over his shoulder.

"No you wouldn't. You'd be lost without me." She laughed as she threw an arm around his shoulders.

Castiel just gave a disgruntle growl, knowing she was right.

"Anyways, that's not the only person that looks at you like Tyler does when you're not looking." Charlie shot Castiel a sly look as they stepped outside into the chilly air.

"Who?" Castiel stopped in his tracks, curiosity forcing him to ask.

Charlie looked over shoulder and laughed, not answering as she hurried off to her car.

Saturday morning was unseasonably warm for October. On weekends, Sam would usually start their trainings a little later to allow Castiel to get some sleep. However, Castiel's internal clock woke him up.

After trying to go back to sleep and failing, he decided to get up and go for a jog by himself to clear his head and try to get rid of some excess energy.

He changed into a t-shirt and running shorts and then looked around for his shoes. He quietly snuck into the living room and spotted them by the recliner that sat across from the couch that held a sleeping Dean.

Castiel's house only had two bedrooms so Sam took the guest room while Dean took the couch. Every night, Castiel would hear Sam insist that he and Dean switch between the bed and the couch but Dean always refused, stating Sam was too tall for the couch.

Trying to make as little noise as possible, he made it over to the recliner and bent over to retrieve his shoes. He heard a small groan coming from behind him. Castiel looked over his shoulder at Dean on the couch and saw that the hunter was still asleep. He must be dreaming, Castiel thought.

Once outside, Castiel quickly found his pace and tried not to think about anything at all except for the pavement at his feet and the air warming up around his body as he ran. His mind didn't stay clear for long as he thought about the small progress he made in the translation of the Enochian symbols the night before.

It was indeed a summoning spell for an angel like he originally thought. Now he had a name though. Haniel or the Grace of God. Castiel remembered reading that Haniel was sometimes listed as an archangel. Now he had to figure out why they were trying to summon this particular angel. And who was doing the summoning. He was hoping that once he had the rest of the translation done, it would give him some sort of clue.

An hour had passed and Castiel found himself back in front of his house. He walked back in to see the couch was vacant and the sound of the shower running. Castiel groaned internally, hoping it wasn't Dean in the shower because he always took the longest time in there.

After kicking off his shoes, Castiel walked into the kitchen to grab of bottle of water and saw a note from Sam on the refrigerator saying he would be gone for the day to help someone named Bobby with a small case nearby.

Castiel drained the water bottle, tossing it in recycling before shucking off his soaked t-shirt and tossing it in the hamper in the laundry room. The sweat was starting to dry on his skin, making him feel disgusting and Dean was still occupying the shower causing him to huff in frustration.

Afraid that Dean would take all the hot water again, he made his way to the bathroom and called out to Dean. When there was no answer, he shrugged and opened up the door.

"Dean, are you about done?" Castiel called out in the steam filled room. Castiel walked over to the toilet, shut the lid and sat down.

"C-cas?" Castiel raised an eyebrow at Dean's shaky tone and the fact he called him Cas instead of using the annoying nickname of Doc that he christened him with.

"Hurry up, I need to take a shower." Castiel groused.

Dean peeked around the shower curtain, only his flushed face and a freckled shoulder was showing. Castiel snorted when he saw Dean's hair spiked up into a mohawk with shampoo.

"What are you doing in here and why are you naked?" Dean sputtered, gripping the curtain tighter in his hand.

"I'm trying to hurry you up before you take all the hot water. What do you mean naked? I'm wearing shorts. Didn't take you as a prude." Castiel laughed at Dean's expression.

"I'm not a prude. I'll show you who's the prude." He started to push back the curtain but Castiel jumped up and stopped him, grabbing Dean's hand.

"Please, I don't want to be blinded." Castiel felt his cheeks grow warm. It was because of the steam, not because he was blushing.

"Blinded by my male beauty you mean." Dean smirked. "Now, would you get the hell out of here so I can finish my shower?"

"Just hurry up. I'm going to work on grading since Sam's out today."

"Nope, I'm taking you out today to practice on your shooting. Let's see if you can handle a gun better than you can a knife."

Castiel frowned. "I have work I need to get done."

"Hey, this was your idea to be trained like a hunter. If you don't think you can handle it…"

"Fine. Just finish up your shower." Castiel growled, eyes following a water droplet as it trailed down Dean's neck to his shoulder.

"Cas?" Castiel looked over to Dean's face to see green eyes slowly flicking down Castiel's body and back up. White teeth flashed as Dean gave Castiel only what he could construe as a flirty smile.

"You gonna hold my hand all day, big boy?" he asked before giving Castiel a wink.

Castiel jumped away, forgetting he had grabbed Dean's hand and hadn't let go.

Dean sent him another wink before closing the curtain, laughing.

Castiel glared at the closed curtain and started to storm out of the bathroom, but then a mischievous smile over took Castiel's face. He went over to the toilet and flushed it.

A few seconds later, "Sonuvabitch!" followed when Dean got blast with cold water.

Castiel laughed all the way back to his room.

First, sorry it took months to update this and that it's pretty much a filler chapter. I didn't know where I wanted to take this story, but I now have a rough idea. It probably won't be as long as my other stories, probably around 10 chapters.

Thanks for the reviews, follows and favorites! They always make me very happy. :) Thanks for reading!
