A/N:For some reason, this again turned out a lot longer than I anticipated. This is what happens when you're constantly turning over the same lyrics in your head when at work.

I know Charlie and Cas don't meet until 10x18 – creative license, guys.

Adorable

Charlie nudged Sam with her elbow as they followed Dean and Castiel into the Bunker after a successful if somewhat messy hunt.

"Just look at them – they're adorable, aren't they?", Charlie whispered and giggled as she pointed to the angel and his friend making their way downstairs, busily engaged in their own conversation.

Sam chuckled at first, but then he saw Charlie raising an eyebrow with a questioning expression.

Sam looked back and forth between his brother and Castiel and began to shake his head while staring at his friend in utter amazement: "Are you serious? I mean... come one, they're... They're..."

He made a helpless gesture with his hand and shrugged.

Charlie stopped halfway down and patted Sam's shoulder apologetically: "Sorry to burst your bubble man, but yes, I'm serious. How come you haven't noticed this before?"

"There's nothing to notice, Charlie", Sam said defensively.

Charlie chuckled, leaned close to Sam and whispered in his ear: "Dean totally has the hots for Cas; and just watch that adorable mess of an angel staring at him..."

She took the last two steps down: "You're lucky I'm not betting you on this – I guarantee you'd loose."

Sam stared after the red-head, still shaking his head. Dean and Castiel? No way. That was never going to happen.

Despite his complete refusal to believe Charlie, Sam began to notice things he'd written off as being normal weird for Cas and Dean before...

Watching them became an infuriating habit of Sam's.

The first thing that struck him as odd was when Cas left, soon after Charlie. He'd said his goodbyes and then walked off, and Sam found himself watching his brother stare after the angel with a strange expression. He was good at reading Dean's emotion off of his face, but he'd never seen his brother look like this. It was odd.

Next time they ran into Castiel while on a case, he noticed how often the angel's eyes strayed to wherever Dean was standing, and how he quickly averted his gaze whenever Dean turned to talk to him.

More than just once Sam was sure he noticed a light blush creep over his brother's face when he was purposely not looking in Cas' direction.

It was irritating enough before Sam noticed that Castiel and Dean for some reason had stopped touching altogether. Usually when they met, they'd hug; but now there wasn't even a handshake.

There had been many times Dean would slap the other's shoulder when he was being ridiculous, or when he'd done something right, or just because Dean found something the angel said hilarious, but that had stopped as well.

As the weeks passed, Sam watched how that crooked smile which Castiel had reserved for Dean ages ago began to waver and than vanish altogether, and he saw that when his brother looked at the angel, his expression appeared torn between sadness and frustration while he strained to smile.

Sam realised that maybe, after all, Charlie might just have been right in suggesting that there was something going on between Cas and Dean; and watching the two of them not figuring out what was happening made Sam decide it was up to him to help them along.

He began to deliberately leave the two of them alone whenever possible, forcing them to talk to each other instead of mostly to Sam. He stayed out later and longer than he was used to when Cas was staying at the Bunker; he even asked Cas to come over and check if Dean was alright because he had a 'funny feeling'; but the two of them ignored all these possibilities and carried on as they were: Awkward and increasingly distant.

If he didn't knew any better Sam would've guessed they were trying to detach themselves from each other.

There just didn't seem to be any chance that either would talk about the way he felt.

Then came the evening on which Sam reached his breaking point.

Castiel had phoned ahead – had phoned Sam – to ask them if he could stay at the Bunker for a few nights. He'd been in a fight and to not strain his dwindling grace overmuch, he needed a safe place to heal.

Sam had said yes, told Dean and then used a supply run as an excuse to leave and let Dean deal with Castiel on his own.

When he returned to the Bunker, he was careful to enter as quietly as possible to not interrupt whatever they might be doing.

To Sam's immense disappointment, there was nothing to interrupt, really.

Dean was just checking how bad a bleeding scratch on Cas' face was, but his fingers barely touched the angel, and Cas was busy to look anywhere but Dean's face.

They weren't talking; and they both looked extremely unhappy.

Sam slumped down in a chair next to Cas and blurted out: "Just admit that you have feelings for each other and get it out of your system or whatever; I don't really care, just stop this stupid charadeso we can get back to being normal!"

Dean stepped back from Cas and raised his hands: "What are you talking about?"

That's when Sam just lost it: "Dean, can't you be honest about your feelings for once in your life?! It's so obvious you're... Dammit, Dean, just kiss Cas already!"

As soon as the words were out of his mouth, he felt he should regret them – but he didn't. He was fed up with this ridiculous denial of feelings.

There were a few moments of confused silence before Dean said: "I have no idea what you're talking about" at the same moment as Cas said: "Why would Dean even want to kiss me?"

While the first sounded angry, the second's voice broke, and despite the fact that Dean had spoken at the same time as Cas, he still heard the shaking in the angel's voice. Frowning, he turned back to him and found Cas' blue eyes fixed on his face.

Sam wondered if he should say something else or if maybe now they finally got it.

"Would you actually want me to kiss you?", Dean asked with an expression of utter amazement on his face.

Cas's gaze moved from Dean's eyes to his lips and then back up again in an instant, but Dean had noticed it nonetheless. Judging from the blush returning to his cheeks, this was answer enough.

"Oh...", he whispered as a huge variety of emotions crossed his face. Cas' eyes became even wider, something Sam hadn't thought possible.

Dean blinked and, suddenly remembering what he had been doing, continued with inspecting the scratch on Cas' forehead. This time, he carefully touched the angel with his fingertips. Cas inhaled sharply as Dean's fingers moved down in a slow caress, finally stopping at Castiel's lips. Neither man seemed capable of moving, but then Cas' crooked smile was back, and Dean's face lit up.

Sam hadn't seen the two of them look this happy in forever.

He stared, transfixed, until suddenly Dean looked up and caught him watching: "Why don't you head out for a while, Sam?"

He felt himself smirking and Dean hurled the towel at him which he'd held in his left hand to wipe away the blood on Cas' face. He only barely avoided it.

"Get out, Sam, you pervert! This is private!"

Sam finally stood so abruptly he made his chair fall over, really feeling like a voyeur as he stammered: "I will. Definitely. You two have... – See you in the morning, I guess..."

Sam waited until the door had closed behind him before he pulled out his phone and dialled Charlie's number.

She didn't so much as say hello but instead burst out: "I was right, wasn't I? Admit it! Admit it!"

"Yes, you were right, Charlie..."

"Well, I am a genius", she giggled and then begged excitedly: "Tell me everything!"
