27. Jealousy

"Dude, what's up?" Dean said to Sam, who had been fidgeting for the past hour. "Even Cas can stay still longer than you lately!"

Cas bitch-faced him (something that he was surprisingly good at – maybe Sam had been giving him pointers) and went back to sketching, a hobby he excelled at. Sam just rolled his eyes.

"Nothing's up, Dean," he said. "I'm just going out tonight. Maybe hit up the bar or something."

"Great! I could do with some pub beer," Dean said.

"No!" Sam said quickly. Dean looked at him suspiciously. What was his baby brother trying to hide? "I mean, no. You and Cas'll have the bunker to yourself without me bitching in your ear about privacy."

Now Dean was really suspicious. Since when did Sam ever admit that he bitched? He must really have wanted to go out alone that night without Dean there to embarrass him and Cas to act all weird and scare everyone off, which meant –

Oh. Damn! Dean connected the dots in his head. Sam had been acting like this for a couple of weeks now but he hadn't noticed, having been occupied with Cas.

"It's a girl, isn't it?" Dean grinned. Sam jumped and shot him a startled look. "You've got a girl, Sammy!"

"What? No!" Sam said quickly. Dean started to cackle. Sammy had a girl!

"Well, is she hot?" Dean said. "Blonde? Brunette? Huge rack? Super smoking sexy?"

For some reason, Cas scowled. Dean wondered what was up with him.

"Dean! Stop it!" Sam complained. "She's not a supermodel! She loves books, like me. Unlike some of us, I don't pick girls based just on their looks."

Cas' scowl deepened and he pressed his pencil harder into the page. Dean shot him a weird look.

"So it is a girl!" Dean said smugly. "Why didn't you tell us, Sammy? I'm glad you're finally letting loose! So, tell big brother Dean all about your precious."

Sam rolled his eyes.

"I've been seeing her for a couple of weeks now," he said. "Her name's Rose. I was going to bring her around once I got around to telling you –"

"Bring her around? Here?" Dean said sharply. "Sammy –"

"It's okay," Sam said. "I told her about our life a few days after we got together. I won't make the same mistake that I made with Jess."

"And she believed you just like that?" Dean said disbelievingly. "She didn't try to throw you into Australia or something?"

"Uh…" Sam grinned and rubbed the back of his neck awkwardly. "She kinda likes the Supernatural books…"

Dean groaned loudly.

"Sammy, so help me if she's another Becky –"

"She's not! She's really not!" Sam said. "Do you think I'd be with her if she was another Becky?"

"She could've made a crossroads deal," Dean reasoned. Sam rolled his eyes.

"She was a Dean girl before she met me," he said. Dean smirked widely. Now that was what he was talking about! Nice to get some attention from the fangirls! "She didn't believe me when I told her I was Sam Winchester – she thought I was playing a joke. Then she told me that she preferred you more before saying that she'd settle for me and we've been together ever since."

Dean, who was grinning widely, didn't see the ugly look on Cas' face or the way the tip of his pencil snapped from the force of pushing it into the page.

Sam brought his girlfriend around to the bunker the next night and Dean took the opportunity of her awestruck gazing around the place to take a good look at her. She wasn't supermodel hot but she was pretty, with dark blonde hair tied in a loose bun at the nape of her neck, grey eyes behind square glasses and a red blouse and jeans.

"You weren't kidding! This place is amazing!" she exclaimed. Sam grinned from next to her.

"Dean, this is Rose," he said. "Rosie, Dean. And Cas is just over there with him."

Dean smirked and waved. Castiel looked up from his book and gave a curt nod.

"Ohmigosh! You're Dean Winchester!" Rose squeaked. "You're ten times hotter in person!"

"Thanks, Rosie," Dean winked.

"Dean, don't steal my girlfriend!" Sam whined but he was laughing. Cas snapped his book shut abruptly.

"Sorry but I am feeling unwell," he said brusquely. "I apologise, Rose. It was good to meet you."

Cas made a quick escape. Dean frowned after him.

"Sorry about that," he said. "Cas isn't usually like that. He's usually pretty chill with everyone he meets."

"He's human now, right?" Rose said. Dean nodded, not surprised that Sam had told her about what had happened after the last Supernatural book was published. She suddenly froze and a wide grin split her face. "Wait! Are you – is it –"

Dean sighed and nodded. Rose let out a high-pitched squeal.

"OHMIGOSH! DESTIEL IS CANON!" she shrieked. Dean winced and plugged his ears, glad that Sam was the one with the fangirl and not him. Although she did remind him of Charlie and Charlie was the coolest fangirl around, so maybe Rose wasn't too bad.

"He's been moody all day and I don't know why," Dean said. "He won't tell me a damn thing!"

Rose frowned down the hallway and then her face lit up in realisation.

"Oh! I think I know what's wrong!" Rose said. Dean shot her a questioning look. "He's jealous, you idiot! Sam told you that I was a Dean girl, right? And I just had that fangirl moment just then over you. And we all know what you're like with the thought of girls. Cas probably thinks you're losing interest in him!"

Dean blinked.

"That's ridiculous!" he said. "Why the hell would I throw him aside for some random girl? No offence."

"No offence intended," Rose said easily. "I don't even want you anymore anyway – I have my moose. But that's jealousy. When do you ever think straight when you're jealous? Go talk to him, you idiot!"

"Alright." Dean stood up. "Don't get up to any funny business, you two. And if you do then for God's sake, put a tie on the door! I don't need to see any more of my brother than necessary!"

"But it's a beautiful and natural act," Sam bitched, reminding Dean of what he had said all those years ago after making his crossroads deal.

"Doesn't mean I wanna see it. Nice meeting you, Rosie."

Dean headed down the hallway to their room. Cas was lying on his side on the bed, staring at the wall with a glum scowl. Dean felt horrible for not picking up on this before.

'What's up, Cas?" he said.

"Nothing," Cas mumbled. "I told you. I'm feeling unwell."

"You wouldn't happen to be a bit jealous, would you?" Dean said. Cas just shrugged. "Cas, what the hell reason have you got for being jealous?"

"Why don't you go ask your fangirl?" Cas muttered bitterly. Dean winced and lay down on the bed next to him, propping himself up.

"You don't seriously think that I'm gonna forget about you for some girl who's already been taken by my brother, do you?" he said. Cas didn't say anything. "Come on, Cas! Do you really think that little of me? Have I even looked at a chick since being with you?"

"You described Rose in very glowing terms," Cas said sulkily.

"Jesus, I was just teasing Sam!" Dean said exasperatedly. "I don't care if she's got the biggest rack this side of the universe and is the hottest woman alive!"

Cas' lack of response infuriated Dean. He grabbed Cas and rolled him onto his back, startling his angel.

"I didn't want to have to do this." Dean straddled Cas. "But you left me no choice."

Before Cas could say anything, Dean leaned down and smashed his lips against his angel's. Cas made a strange, high-pitched sound that immediately sent all of Dean's blood rushing south and he grabbed Dean's face and pulled him closer, returning the kiss with equal intensity.

"Believe me now?" Dean gasped when they separated. A flushed, panting Cas nodded.

"I apologise for ever doubting you, Dean," he choked. "I think I require further punishment. Would you do the honours?"

Dean's eyes lit up devilishly and he dived back in, ignoring the knock on their door.

"I assume you two are at each other like rabbits again so I just came to say that Rosie and I are going out!" Sam called.

"Enjoy your gay sex!" Rosie chirped. Dean heard them laughing all the way down the hallway but he just didn't care.
