Cas strolled down the corridor. He thought Dean would have finished his shower by now, he felt happy that Dean trusted him with Baby. He smiled to himself.

He walked down to the changing room, feeling more confident since their last conversation.

Dean looked upset. His eyes weren't as bright as they usually were, and his usual small smirk had disappeared.

Cas went over to comfort him, but let his eyes drift to Dean's exposed, toned abs.

Why did he have to be so damn hot..?

No! He's upset- I need to comfort him.

Cas thought to himself.

Dean looked up, his gaze softened as he saw Cas standing in the corridor.

He felt a warm blush graze his cheeks as he felt Cas' eyes linger on his torso. He became very aware that his shirt was unbuttoned, and hastily rectified the situation,still maintaining eye contact with Cas.

Damn. Why was he sexy putting his clothes on as well?

Dean smirked.

"Cas, stop checking me out."

Dean teased, playfully punching Cas' arm.

"Do you wanna go for a walk, maybe clear your head?"

Cas asked, staring pleadingly into Dean's eyes.

Dean gave Cas a sad smile. That was exactly what he wanted to hear.

The pair strolled down the corridor.

"What's wrong, Dean?"

Dean sighed.

"Sam."

Cas furrowed his eyebrow.

"What do you mean?"

"Sammy said that he wanted to be just like me,"

"Of course he does."

Dean stared at him in bewilderment.

"What are you talking about- Sammy shouldn't wanna be like me!"

"Why not?"

Dean's eyes widened.

"Why not? Where do we start? I'm good for nothing- literally nothing- The only thing I'm good for is Quidditch, and where is that gonna get me in life- nowhere! Sammy has brains, he has a future, he could be somebody, but-"

"DEAN- SHUT THE HELL UP!"

Dean's eyes widened, mouth agape.

"Dean! How do you not realise how amazing you are?"

Dean frowned.

"Cas, Stop trying to-"

"No Dean! I don't think I can stand here and sit through another minute of you putting yourself down!"

Cas was almost on the verge of tears.

Dean could feel his eyes watering.

"Cas, I, I just-"

"No! Why don't you believe me when I tell you that you're amazing?"

Cas felt his voice go hoarse.

"Cas..."

"I'll see you in class."

Dean watched, with tear-filled eyes, as Cas stormed down the corridor.

Dean returned to his dorm room. He lay on the bed, stared at the ceiling and sighed.

Shit.

I shouldn't be doing this. This was a mistake.

Dean thought to himself.

He entered the library, Cas always went there when he was upset.

There he was, sitting at the table in the far corner.

Of course, he would take any opportunity to be antisocial.

Dean smirked to himself.

"Cas."

Dean whispered.

Cas looked up and sighed.

"Hello Dean."

"Listen Cas, about earlier-"

"No, I'm sorry Dean. I shouldn't have over reacted, it's just I can't stand to hear you talk about yourself like that."

Dean sat down on the sofa beside Cas.

"Yeah, well I understand, if you ever started talking like that- I- I don't know what I'd do."

Cas turned to Dean smiled.

Dean let his eyes drift from Cas' eyes, down to his lips and back.

He leaned forward and-

"Anyway we should probably get to class!"

Cas spluttered.

Cas hastily got up from the sofa, heading to the potions class, dragging Dean along with him.

Potions was their favourite class, because Cas and Dean were partners. Dean let Cas do all the theory work. Cas didn't mind, Dean was better at all the practical stuff anyway. Cas would always put too much of something in, or not boil it right.

Dean was always better at all the chopping, crushing, stirring.

Probably because of those big, muscular arms.

Cas thought to himself.

Dean watched as Cas intensely scribbled everything down from the board. He loved doing practicals, besides the last time Cas did a practical was first year, where he messed up so badly, they got into trouble, and had to clean up their mess. It took them the whole weekend.

Dean smirked to himself.

He wondered how Sammy was doing with flying.
