Right I've decided to start another story due to my extreme boredom and my love of everything Caskett! The start might put some of you off but I promise lots of Caskett coming up in the future. Reviews are love and I appreciate every comment made, positive or negative. I will probably update this one slower than the others but I will try to do longer chapters!

Prologue

July

"Wow, congratulations" he mumbled as she stood there staring at him, her hand behind her back hiding the ring she was not yet prepared to show. She couldn't get over it herself, that she was going to be married to Josh and most of all she couldn't get over the fact she'd said yes. "I don't know what to say" he whispered, his heart breaking as he stared at her desperately forcing a smile onto his face.

"Congratulations is enough" she mumbled desperately wanting to have him hug her and tell her it was the right decision, that he was pleased for her. She didn't know why she so desperately needed his blessing but it felt right to want it after all these years of working together, it felt right for him to say that he was happy for her. "We're getting married in September, you will come won't you?" she asked causing him to sigh.

"If you want me there" he whispered causing her to grab hold of his hand, shocking them both slightly.

"Of course I want you there Rick, your my best friend, there's no one else I'd want more at my wedding than you" she declared causing him to nod as she sighed. "It's only going to be a small thing, just friends and family" she added, not knowing why she was going into so much detail about the wedding her and Josh had managed to plan in one night. Neither of them wanted a large ceremony, they just wanted a small event with the people they loved most where they could celebrate their own love. "Alexis and your mother are invited to".

"I'll tell them that" he whispered as she sighed, slipping her hand away from his. "Congratulations again Kate" he declared before walking awards the precinct lift, shock covering his face completely. Kate was getting married to Josh and it seemed like she was completely set on the idea. She had everything planned which didn't surprise him when it came to Kate. Hitting the button, he didn't notice that she was still watching him from further down the corridor, her fingers fiddling with the engagement ring on her finger. She still hadn't gotten used to it and the feel of it on her ring finger felt strange and she often found herself wanting to take it off from the moment he'd put it on her finger the night before. She loved Josh, she knew that and he was good for her, he understood how much her work meant to her and supported her through everything but yet she felt like something was missing. She just hoped marriage would fill that hole in her heart. Watching as the lift doors opened and Rick stepped in, she bit her lip as he turned and faced her, a small smile on his face as she smiled back before looking down at her ring and sighing. Why couldn't she just be happy about it like any other woman?

XOXOXO

September

Staring at her as she danced on the floor with her husband, he sighed taking another sip of the wine he ordered himself, his daughter and mother smiling and commenting on everything the couple did like they'd done the whole day. The ceremony had been small just like Kate had described to him but he kept thinking about how certain details weren't like Kate, how the flowers weren't her favourite and how the song for their first dance was one of the songs she'd once told him she hated the most. Hearing the claps, he looked up to see more people walking onto the dance floor as the bride and groom separated, Kate quickly walking towards him, a smile on her face.

"Rick dance with me" she whispered as he stared at her, watching as she held his hand out to her. He had to dance with her however much it hurt, today was about her, it was her big day and he wasn't going to deny her anything. Taking her hand, he slowly led her onto the floor as they got themselves into a dance hold in silence. "What are you thinking?" she asked.

"Just about how beautiful you look Kate" he announced, deciding that he had to say something about how breath taking she looked dressed in a simple long white dress with her hair pinned back, curls delicately framing her face. She'd gone for simple which wasn't surprising and yet she looked stunning.

"Did you know you're the first man to tell me that today?" she declared causing him to raise his eyebrows as she turned to look at the man who was now her husband who was busy in discussion with people from his work. "He hasn't even noticed really" she whispered causing him to sigh, noticing the disappointment in her voice. "I thought he'd notice personally but he's not even said a word to me since the ceremony".

"Kate" he whispered as she sighed and smiled up at him. "You two are going to be very happy" he declared as she nodded slowly. "Although why you danced to a song I know you hate more than anything, I will never understand" he declared causing her to laugh as he spun her around slowly.

"It's our song apparently" she muttered before rolling her eyes. "You know me Rick, I've never really paid much attention to that sort of stuff" she whispered as he nodded the song they were dancing to quickly coming to an end causing her to move away from him. "I probably won't see you for the rest of the night, I have to socialise with people apparently" she declared before rolling her eyes once more. "But Monday?" she asked.

"Monday?" he whispered causing her to nod, a small smile covering her face as she found herself laughing at the fact he couldn't remember work, questioning how much he'd had to drink as she looked at him.

"Work" she declared as he looked down at his polished black shoes and the end of her white dress. "Rick what's going on? What aren't you telling me?" she whispered as he sighed and looked back up at her.

"I didn't want to tell you this tonight, it's your wedding day and it's not fair but I'm not coming back to the precinct" he declared as she felt the world smash around her. "I've written the last NikkI Heat and well I don't need research anymore, I've got enough to last me until the end of my life" he declared causing her to shake her head.

"You don't get to do this Rick, you don't just get to end it like that without a word or even bringing it up with me, what about what I want?" she asked before grabbing his hand and dragging him pass the well-wishers who wanted to congratulate her on her marriage. "You're my partner Rick" she announced.

"I'm not a cop Kate, we knew today was coming" he whispered as she bit her lip. "It's just time Kate to start a new chapter, you've got Josh and married life now and well I've got to find something else, Nikki Heat has run its course and it's time for me to move on and search for a new muse" he declared as she continued to shake her head.

"So that's it your just leaving and replacing me with someone else" she mumbled causing him to nod, her hand smashing against his cheek gaining the attention of most the people in the room who all stared at her. "Just go Rick, I don't want to see you again" she announced before walking towards Lanie and Esposito who were stood watching. As Lanie opened her mouth Kate quickly shook her head. "Just don't" she whispered causing her to friend to nod as they all watched Rick grab his coat and leave the building, no one noticing the tear creeping down Kate's cheek as she realised that although one chapter was starting, the biggest one in her life was ending at the same time.
