Sam slumped down in to the chair, slightly out of breath and little damp from his morning run. He gulped down half a bottle of water wondering why Dean wasn't awake yet. At that very moment he heard Dean's bedroom door open and his footsteps approaching down the corridor, and Sam braced himself for the inevitable teasing when Dean realised he had been exercising. But his brother didn't even mention it as he entered the kitchen wearing nothing but a bathrobe and a little smile.

"Mornin' Sammy," he said, clapping his brother on the shoulder as he passed him on the way to the fridge. He took out the milk, grabbed a bowl and poured himself an enormous serving of cereal that he immediately started eating by the shovel full.

"What's with you?" Sam asked.

"Nothing," he replied through a mouthful of Cheerios. "I'm not allowed to be happy in the mornings?"

"It's the afternoon actually," Sam said, checking the clock to see that it had just passed midday. He continued to watch his brother curiously, wondering what could be wrong. Sam shook his head slightly, lamenting the fact that their lives had got to the point where seeing Dean happy was so rare that it was considered suspicious.

"So…" Sam said. Dean looked up at him.

"So what?"

"You're not going to make fun of me?" he asked. Dean took an impassive glance at his sweat-darkened t-shirt and shorts and he shrugged.

"For going out on a run? Whatever makes you happy man, I'm not gonna judge." Sam opened his mouth to voice his confusion when Cas walked in to the kitchen. He looked completely different in nothing but boxers and a t-shirt, his hair fluffy and unkempt. Sam wondered why the angel had bothered to change his clothes when there was no need for him to shower or sleep.

"Good morning, Sam," Cas said, sitting himself down at the table. "Dean," he added. Sam didn't miss the little smile that pulled at the corner of the angel's mouth when he met Dean's eye.

Sam's mouth fell open and his eyes grew wide as he looked from his brother to the angel. He found himself suddenly on his feet. In his haste he knocked over his water bottle which spilled all over the wooden table, running towards Dean and pooling around his cereal bowl. He stared at the bottle, went to pick it up, changed his mind, stared at Dean, then at Cas, then hurried from the room without another word.

The next thing he knew he was pacing his bedroom, thoughts and realisations flying so quickly through his mind that he couldn't focus on any of them. He heard footsteps and turned to see Dean leaning on the doorframe, watching him carefully.

"Something wrong, Sammy?" he asked. He continued pacing with no idea where to begin.

"You and Cas?" he blurted out at last. "You. And Cas. I mean… when did… what… I don't…"

"If you could finish a sentence at some point that'd be super," Dean said. Sam paused for a moment before turning to his brother.

"What the hell are you doing?" he asked. Dean's lighthearted smile dropped instantly.

"I'm doing what makes me happy."

"He's an angel, Dean. And he's -" Sam cut himself short, too shocked and uncomfortable to finish.

"No, go on," Dean said. "Say it."

"He's a guy!" Sam said at last, unable to keep the disbelief from his voice.

"So?"

Sam saw the anger in Dean's eyes and realised that he was treading on thin ice. He held his hands up in surrender. "I'm not saying I've got a problem with it, but I wish you'd told me," he said. "It's just a surprise, that's all."

"Jeez, Sammy, what show have you been watching?" Dean asked. "You really never saw this coming?"

"Cut me some slack," he said. "I just never thought you were…"

"Gay? I'm not. I still dig chicks most of the time but c'mon Sam, this is Cas we're talking about. He's always been my exception." There was a long silence after that, and Dean waited coolly for Sam's next words, although Sam could see the anxiety behind Dean's pretend nonchalance.

"You love him?" Sam asked, and almost instantly a small smile crept on to Dean's face.

"Like you wouldn't believe."

Before Sam could say anything else, Cas walked in and stood beside Dean.

"Is everything alright?" he asked, frowning slightly as he looked from Dean to Sam.

"Yeah, Sammy," Dean said, slipping his hand in to Cas's and watching his brother carefully. "Everything alright?" Sam's eyes narrowed slightly, Dean's deliberate provocation not escaping his notice. But then he just shook his head slightly and smiled.

"Whatever makes you happy, man," he said. "I'm not gonna judge." Dean laughed as Sam repeated his own words back to him. All three of them stood in Sam's room for a moment longer, no one quite sure what to do.

"C'mon," Sam said eventually, turning to his bed and picking up a newspaper. "I think I've found us a case in Idaho."

"Great," Dean said, turning to leave, still holding Cas's hand. "Hey, Sammy," he said, turning back to face his brother just as he reached the doorway and smiling warmly at him.

"Yeah?"

"Jogging is for losers."

Sam laughed. "Jerk."

"Bitch."
