A/N: you are seriously the best people ever, thank you so much for reviewing/following/favouriting! Time for jealous Beckett..

2x12 - A Rose for Everafter.

"Is there no paperwork we can do?" Castle asks.

Looking at him from across the desk, Beckett raises her eyebrows. "Wow, you really must be bored if you're offering to do paperwork."

"Beckett, it's -" he checks his watch, "2.30 in the afternoon. We've been here since before 9 with no cases and you had finished the paperwork by 10, at which point playing candy crush on my phone was still keeping me occupied. But right now, I'm bored!" They'd been sat there for the best part of four hours with nothing to do. They had no new cases and Espo and Ryan had headed down to annoy Lanie for a bit.

"You do realise you don't have to be here, right? Six years in and I thought you'd have figured out you're not actually a cop. If you wanna go, then go."

"And leave you here without my irresistible charm for company? No, I wouldn't do that to you. Besides, we're partners, I wouldn't be a very good one if I left you now."

Beckett surveys him for a moment. "You have a chapter due, don't you?"

"I, uh..why, what-" Beckett raises her eyebrows again. "Oh alright, yes, I have a chapter due. But I don't know what to write! And Gina keeps calling, demanding to know why she doesn't have it yet - she wants me to go out for dinner tonight! She's saying it's to discuss another contract with Black Pawn but I know it's only so she can harass me for the next chapter."

"Oh well if Gina wants you to go out for dinner then don't let me and my non-existent cases stand in your way." Beckett says, a slight touch of sarcasm in her voice.

"Katherine Beckett-Castle are you jealous? Of Gina?" Castle asks incredulously.

"What? No, no I'm not jealous? What am I, fifteen?" Now it was Castle's turn to raise his eyebrows. Beckett sighs. "Okay, fine. Yes, I am a teeny tiny bit jealous. The past few weeks I've hardly seen you outside of the precinct. And I'm not saying I don't want you spending time with Alexis, you know I'd never come between your relationship with her but if you're not with her, you're with Gina. We've been married three years now and I don't want us to get complacent."

Castle tries to keep his smile to himself, he loves seeing her all riled up like this. "Kate, I'm not getting complacent. Do you remember how much I had to convince you to be with me in the beginning? I'm not blowing you off that easily." He breaks off at the slight quirk of her lips. "Mind out of the gutter, Beckett." He says.

Beckett couldn't help it. She was just as bored as he was and when he mentions 'blowing you off'? Well how could she stop her mind from going down that path? However now, she was extremely close to dragging him into the supply closet and showing him just how well she could blow him off.

Castle could tell what she was thinking. Her eyes darkened and a slight flush was forming on her cheeks. Kate Beckett-Castle was turned on at something he'd said out of hand. And the jealousy thing? Sweet Jesus, he was close to taking her right here on the desk. Deep breaths, Castle. "So, you're jealous, hey?" He says, trying to steer the conversation back towards something slightly less..inappropriate for the work place.

She loses her smile and looks almost hurt. "Hey, I'm only teasing." He tells her. "Actually, it's pretty damn hot." She bites her lip and gives him a coy look from under her lashes. "Yep, and so is that." He shifts slightly, trying to get more comfortable in his chair. Thank god there's no one else around. "Remember how jealous you got when Kyra showed up?"

"Castle, for the last time, I was not jealous!" She lies.

"Oh you so were, Kate, it was obvious!"

"Where's Castle?" Ryan asked, surprised at the lack of Beckett's partner.

"I don't know. Figured the death of a bridesmaid would be right up his street." Beckett said. She'd tried calling him but he hadn't answered. She wasn't worried, he'd probably just duct taped himself to a chair or handcuffed himself to the bed - apparently all these crazy things were research for his latest Nikki Heat novel.

"Heard 'wedding' and probably got cold feet." Ryan said. And then realised what he'd said. "Oh crap, I'm sorry Beckett, I didn't mean-"

Beckett smiled. "It's fine, Ryan. It's not like he has the best track record, anyway." She replied, noticing the tension leaving Ryan's shoulders. She knew Castle was committed to their relationship, hell, it had been him that had said they'd be married one day. He loved her, she knew that.

After Castle had turned up - she was right, he had duct tape on his pants - he caught up on the case. "So, who's the unlucky bride?" He asked.

"Uh, her name is.." Ryan said, looking through the paperwork he had for the name he needed. But Castle got there first.

"Kyra?" He said.

"Rick? Rick Castle?" The bride replied.

Beckett heard this exchange. "You two know each other?"

"That would be an understatement." He replied.

Oh. Oh. He knew her? How? Were they friends? More than friends? Beckett wanted the answers to all of these questions. Now, preferably. Woah. She thought. What's wrong with me? And then it hit her - she was jealous. Well, who wouldn't be? Her boyfriend had showed up to her crime scene and seemed to know the bride in a way that suggested she was more than just an acquaintance. She needed to know what was going on. However, before she could interrupt their little catch up, she had a development on the case.

"Castle, Lanie's got something for us." She called out.

"I'll catch up." He replied.

"Hmm, okay." Okay? Okay? No, this was not okay! He'd blown her off to catch up with a beautiful bride without even an explanation as to how he knew her!

"Okay, yeah I was a bit jealous." She admits. "But you just swanned off to talk to her, didn't even tell me how you knew her!"

"I was shocked, that was all." He says. "I hadn't seen her in years and then she shows up as part of a case - at her own wedding! I wasn't thinking straight."

"Yeah, well that much was obvious. You made it out like I wasn't anything important that day!"

Even Lanie picked up on Kate's jealousy.

"So, how's everything going in the bridal sweet? Not the day they had planned." Lanie said after filling Beckett in on what she'd found on the victim.

"Yeah, or the suprise guest. Apparently, Castle has a history with the bride."

"Ancient, modern or sexual?" Lanie asked.

"Seems like all of the above." Beckett replied.

"You okay with that?"

"Yeah, why wouldn't I be?" No. No, she was not okay. Her boyfriend was currently in the other room with someone she was assuming he'd had a relationship with and had seemed to have forgotten Kate even existed.

Kyra was leaving with her fiancé as Beckett went back to find Castle.

"Kyra Blaine. Wow." He said.

"I take it she was someone very special."

"She's the one that got away." He said simply. Oh great. Brilliant. Way to make her feel better about this whole ridiculous situation.

"Oh come on, you know I didn't mean it like that!" He says. "But you never forget your first love, even when it's all over and you've both moved on. You're not telling me you can't remember your first love?"

Kate didn't answer. Truth was, he was her first love. She thought she'd been in love when she was a teenager, but that was nothing compared to how she felt about Richard Castle. She'd been pretty crazy about him since their first night together and although she'd had a couple of relationships in the ten years they were apart, none of them had been love. And that was something she'd never told him. "Er yeah, okay fine. Point taken. I'm just saying a little attention would have been nice."

"Point considered. If Kyra shows up again, I'll be sure to show you enough attention too."

"Rick, I swear if Kyra shows up unannounced-"

He cut her off with a laugh. "Kate, I married you, because I love you. And no, it's not because I couldn't have Kyra, it was because I want you. Okay?"

"Fine."

"I'm not complaining, though. Oh no, I have great memories of that case."

"I feel like I know you a little. Nikki Heat, the dedication." Kyra said as her and Kate rode the elevator together.

"Oh."

"I still read all of Rick's books." Oh I bet you do. Shut up, Beckett. She told the voice inside her head. This wasn't Kyra's fault. Really.

"Yeah well, most of that book is just a result of Castle's overactive immagination."

"Its funny that you call him that, 'Castle'." When I knew him, he was just 'Rick', fresh off his first bestseller." Oh great, why not rub it in more that you know him better than I do, Kate thought. "Well, overactive imagination or not, I know he only dedicates his books to people he really cares for." Well, that one she wasn't expecting. It was bittersweet really - Kate knew the dedication in A Rose for Everafter was for Kyra but then he'd dedicated the first Nikki Heat novel to her. Damn him and his stupid books.

"She uh, she told me you only dedicate your books to those you really care about." Kate says.

"And she was right. I do." He replies with a smile. "She was special to me Kate, was. And yeah, maybe it could have lasted but it didn't. And the reason for that is because I'm supposed to be here, with you."

Damn if the guy didn't a freaking answer for everything. He was a nightmare. Her nightmare. But still a nightmare.

"Lanie could tell, the whole time she could tell how I was feeling." Kate says with a smile. "I tried to deny it but I was pretty obvious, huh."

"Yeah, a bit. And oh god when I told you she'd kissed me.."

"You're bringing that up? Now? Seriously Castle, a little tact would be nice. Jesus, I almost shot the woman after you told me that. How could she-?" She stops, seeing him trying not to laugh. "What? Castle, what are you laughing at?" She demands.

"Oh nothing. It's just, you got a little jealous again. It's kinda sexy."

Beckett sighs. He really was insufferable. "Come on, Castle, let's go home. We've got no paperwork and the boys will call if a body drops." She says, picking up her things.

The rode the elevator down to the exit in silence. Kate knew she hadn't really had anything to worry about that day, but it wasn't nice seeing him with Kyra like that. She sometimes forgot that just because he was the only man to have had her heart that it wasn't the same the other way round. Climbing into the car, she began to drive them home, neither of them speaking still.

"Um, Castle." She says, breaking the silence.

"Mmhmm?"

"There's uh, something I haven't told you.." She says. Glancing over at him, she can see he's looking at her expectantly. "You know earlier, when you said you never forget your first love?" She saw him nod out of the corner of her eye. "Uh..well my first love was - is, you." She says, eyes locked firmly on the road ahead of her.

After what feels like an eternity, Castle finally speaks. "I loved Kyra and I thought losing her was the biggest mistake of my life. But I was wrong - not trying to find you after that night all those years ago was the biggest mistake of my life. I love you, Kate. More than anyone I've ever been with, Kyra included." He tells her. "And uh, thank you, for telling me that. I know even now you sometimes find it hard to explain how you're feeling sometimes so that means a lot. And also, I'm kinda glad." He sees her frown slightly at his words but she still doesn't look at him. "I get jealous when I think of you with other men, but knowing you never loved any of them? Well that makes it a little more bearable."

She smiles at him as she parks her car outside their apartment. "I love you," she whispers, and leads him upstairs to show him just how much.

A/N: obviously I had to do this episode! Reviews would be lovely :)
