I'm so sorry this took so long, I just got stuck and then I was too busy and ehhhh life, responsibilities it sucks.
Monday morning Cas sits quietly at the back of the class while Dean teaches at the front. He tries his best to focus on the work but half an hour into lesson and he's only completed two questions from the board.
Cas drops his head in defeat just when he feels a hand grip the back of his chair.
Cas sighs about to lift his head when he feels something being slid under his arm. Turning his head Cas sees something wrapped in tissue on his desk and glances up just in time to see Dean walking away. He discreetly pulls the object into his lap and unwraps the tissue to find a slice of pie. Apple pie. Despite his mood he can't help but quirk a smile at the gesture. Dean doesn't like sharing pie and that first day of class was a one off to make a good first impression, Dean's been selfish with his pie ever since.
Cas wraps the pie back up and puts it in his backpack. He catches Dean's eye and smiles.
Cas' next two classes go by slowly. Cas eventually manages to focus and complete the mundane tasks set. When the bell rings, he sighs in relief and quickly heads to the cafeteria. He passes Sam just as he reaches the Cafeteria entrance.
"Hey Cas" Sam smiles
"Hello Sam" Cas smiles politely.
"Um..." Sam scratches his neck looking oddly nervous "You're good at biology right?"
Cas tilts his head "Yes"
Sam's face turns a light pink. "Well I've got this biology...uh assignment and it's kinda gone over my head. I was wondering if you would..um..if you could help me with it?" By the time Sam stops talking his face is bright red.
"Of course, Sam." Cas offers a reasurringly smile.
Sam seems to relax at that "Great, uh.. would you like to come over my place tonight. If your not busy, I mean."
"That is fine. I'll meet you in the parking lot after class?"
"Yeah" Sam grins "thanks Cas" he waves before continuing down the hall.
Cas watches him for a moment before opening the cafeteria doors.
Samandriel is already sat at they're usual table talking to Dean, who is standing beside the table putting plates down before plopping down in his seat across from Samandriel.
Cas approaches the table hungrily eyeing the plate of pasta placed in front of his usual seat.
"Is that for me?" Cas asks. He's become accustomed to the fact that Dean continually buys him lunch. Though Cas feels incredibly guilty about it most days his hunger normally wins out over his guilt.
"Yup" Dean grins at him.
"Thank you" Cas attempts to say casually but the sincerity behind his words is more than obvious.
Oblivious to staring Samandriel began to complain about the amount homework given in Biology "I mean just because I can do it doesn't mean I should have to. There's plenty of other things I could be doing with my time"
To which Dean responds with "Oh really? Like what?"
"Well, like... sleeping" to which the two continued to tease and challenge one another until they concluded Samandriel hated homework just as much as Dean hated marking work.
The rest of the day is nothing spectacular. Cas finds out he got a B in his English assessment, not the best he's ever done but not bad considering the miserable, sleep deprived state he was in when he did the assessment.
Before he knows it, it's the end of the day.
Cas walks out the school doors intent on walking home before he remembers that he said he'd meet Sam in the parking lot.
He leans against a wall, looking out towards the parking lot. 5 minuets pass before Cas spots Sam talking to Dean. He catches Sam's eye and Sam strides over to him while Dean walks off through the parking lot.
"Hey" Sam grins
"Hello Sam" Cas finds Sam's smile infectious and can't help smiling back.
"You ready to go" Sam gestures towards the parking lot.
"I am" Cas nods before following Sam towards a sleek, black car. The car appears to be much older than the other cars in the lot although in perfect condition, Cas has very limited knowledge about cars but he'd say it was a classic.
Dean walks around to greet him "Hey Cas. Whatcha think of my baby?" His enthusiasm does nothing to help Cas decipher what he's talking about.
Cas stares at Dean and tilts his head to the side. A clear indicator of his confusion.
"That's what he calls the car" Sam helpfully supplies.
"Oh. She is lovely, Dean." Cas vaguely recalls Dean talking about 'his baby's on a few occasions, however he'd assumed Dean was referring to a girl friend or partner. This makes much more sense.
Dean grins wolfishly at Cas "She's a 67' Chevy impala" he pats the car affectionately before opening the back door.
"You wanna sit up front with the cool Winchester or it in the back with this nerd?"
Cas hesitates before deciding it's safer to sit with Sam. Dean is still his teacher after all.
During the short drive Sam and Cas converse idly, topics ranging from school to weekend plans to faviourite flavour ice cream, Cas finds vanilla the most satisfying while Sam prefers strawberry, and Dean doesn't care what flavour the ice cream is as long as it comes with pie!
They pull up outside a small apartment complex. As they unlock the door and head up the stairs Sam speaks up.
"It's not much, but Dean's saving up to buy a house"
Cas nods, unsure how else to respond to that.
On the second floor they walk down the hall to the 4th door on the left, Dean pulls out a set of keys and opens the door gesturing for Sam and Cas to enter first.
Following Sam inside, Cas takes in his surroundings. Sam was right it isn't much, there's a couch, a TV on one side of the room and on the other side is a kitchenette. Cas can see two doors on the far side of the room, one appears to be a bathroom and he assumes the other must be a bedroom, they both appear to be quite small which brings a question to Cas' mind.
"There is only one bedroom" Cas turns to look at Sam questioningly.
Sam glances over at Dean as he closes the door behind himself. "Um yeah, that's my room. The couch is a pull out, Dean sleeps there..." Sam doesn't sound happy about it; it seems him and Dean may have argued about it on many occasions.
"I see" Cas looks over at Dean.
Dean rubs his neck "You want somethin' to drink, Cas?"
"I'm okay, thank you."
Dean shrugs "Suit yourself" before pulling a beer out of the fridge.
"Should we do this is my room?" Sam asks
"Sure" Cas readjusts his bag before following Sam to the tiny bedroom.
2 hours later Sam and Cas have long since stop discussing biology and are instead spread out on the floor in hysterics. That's how Dean finds them when he interrupts to ask about dinner.
"Want Chinese tonight, Sam?" Dean's holding his phone in his hand, ready to dial the Chinese place.
"Sure" Sam and Dean turn to look at Cas simultaneously.
"D'you want to stay for dinner, Cas"
Cas has to bite his tongue and avoid looking at Sam who is giving him the puppy dog eyes. "I wouldn't want to intrude"
"Nonsense. The more the merrier, right Sam?"
Sam nods his head eagerly "Yeah"
Cas smiles shyly "Okay"
Dean grins "Great. Got any specific requests, Cas? I know Sam wants his veggie crap"
"No" and with that response Dean grins once more before leaving to make the call.
Half an hour later Cas is pouring pots of various noodles on his plate, grinning at Dean.
"Good?" Dean's eyes crinkle in amusement.
"Very" Cas stuffs another too big forkful in his mouth, resulting in a collective of noodles hanging from his lips. Dean and Sam chuckle at him; Dean ends up with a noodle in his hair while Sam appears to be wearing half of his dinner.
The three of them watch a movie after dinner. Cas has no idea what is going on in the movie and keeps asking questions although Dean pretends to be exasperated by this both him and Sam patiently answer each of Cas' questions. At 8:20 Cas decides he better head home, declining Dean's offer to drive him; but Dean won't take no for an answer and grabs his car keys.
It's a short drive back with Cas quietly giving directions. They pull up outside Cas' house, Cas is thankful that it's a little too dark to tell how run down the place is.
Dean bids Cas goodnight and waits until Cas is safely inside before driving off.
