I have nothing against the pairings mentioned in this fic. Hell, I ship both of them. But this fic required me to explore what the actual reaction of the characters would be if they were exposed to the idea of both the pairings and the fact that people ship them, so...yeah, no flames about how I hate the ships, okay?

Kate Beckett knew that she had fans. It was evident in the fact that she was usually allowed to skip the queue at her local Walmart and the way people would crowd around her crime scenes asking for her autograph.

Nikki Heat had somehow captured the imagination of average New Yorkers, and the fact that she was the inspiration for the character meant that Nikki's popularity had been transferred to her.

So yes, she knew that she was famous, and as long as it didn't interfere with her work, she didn't really mind. At the very least, her depiction as "a real life avenging angel dressed in NYPD blue" resulted in positive press for the department, so she couldn't complain.

Of course, that didn't stop her fellows cops and assorted friends from sending her any interesting things they found about her or her character on the internet or in the papers.

Apparently, there was an entire cult of obsessed fans dedicated to Nikki Heat. They would meet up to discuss her character development at The Old Haunt, hoping to bump into the inspiration for their favourite characters there. They actually dressed up as her and Castle and went around acting out their adventures.

Hell, there were New York tours based on the places where she had worked the cases that inspired the books, and an old friend of hers from college had sent her a link to eBay where someone was selling homemade doll replicas of the entire team, including Castle.

It did disturb her a bit, how much these people – whom she had never even met – seemed to be interested in her personal life. But she simply chalked it up bored housewives with nothing better to do with their time, and went about her daily life.

Besides, Castle hadn't complained, and there was no chance he didn't know about it. There was no chance she was about to leave herself open to jokes about how she, a hardened police officer, couldn't handle a few fans while Castle could.

Then the stuff started trickling into the precinct.

First was the fanmail. It all started when she walked into work on a normal Monday to find Ryan and Esposito reading mail, of all things.

"What on earth are you two doing?"

The two of them jumped at the sound of her voice, before turning to look at her with smiles that promised nothing but trouble for her.

"Nothing at all," Ryan grinned. "Just looking at a few letters from your…ahem…fans."

"Wh-"

"Here's one," Esposito said, picking up a piece of paper from the disturbingly large file. "Dear Detective Beckett, I am a huge fan of your work. I have been following every case you have ever worked on, and I have come to the conclusion that we are soulmates, meant to be together for- Hey!"

"Give that to me," she said furiously, grabbing the letter. "What the hell is this?"

"Like Ryan said, letters from your fans. There's about five declarations of love, thirty marriage proposals, twenty-two letters of thanks for everything you do – we've put those aside just in case you actually want to read them – twelve promises to murder you gruesomely – all of whose authors are being tracked down right now – and, by far the most interesting, fifteen letter stating all the things the authors do to you in their fantasies."

"WHAT?!"

"Yeah, some of them have even included photos. Like this chick, she's pretty hot," Esposito said, voice a mixture of amused and appreciative.

Kate looked around to make sure that no one else had noticed the pile of letters. Thankfully, the precinct was relatively deserted.

She grabbed the two idiots in front of her and pulled them close. "Listen to me very carefully," she whispered heatedly. "You two are going to burn all of these letters here – maybe not the threat and thanks letters – and are not going to tell anyone about them. Especially Castle. Do you understand me?"

"Fine."

"Can we at least keep the ones that were written to us?"

She had thought that was the worst the Nikki Heat fans could get. She had thought wrong.

A few weeks after the incident with the mail, she entered the precinct to see Ryan and Esposito staring at the computer screen in front of them, utterly horrified.

"Hey guys," she greeted. "What's up?"

"Look at this," Ryan hissed at her, turning the computer to face.

"And…what am I supposed to be looking at?" she asked, starting at the unfamiliar site in front of her. "What exactly is tumblr?"

"A blogging site," Esposito said. "But that's not the point. Look at this."

"RPF. What exactly is that, some new thing to do with the railways?" she asked, genuinely curious.

"Not…exactly," Ryan said gingerly, pressing a few buttons. "Look at it now."

OMG THEY'VE POSTED A NEW FIC! IT'S SOOOOO HOT, YOU'VE GOT TO CHECK IT OUT! RYSPOSITO FOREVER!

"Ummm…wow," she said, taken aback at the obvious enthusiasm for this 'fic' the writer was displaying. "What exactly is a fic? And for that matter, what's Rysposito and why does it sound like something you two would name your love child?"

"No, it's this," Ryan said, clicking a few more buttons and turning the computer towards Kate before he had a chance to catch a glimpse of the screen.

His strong hands stroked up my legs, moving closer to the place I desperately wanted him to touch, while he nibbled at my neck. "Please, Javi," I cried out, voice filled with passion. "Please!"

Kate looked over what she had read once again to confirm what she was seeing. As her mind processed the writing on the screen, she burst out into uncontrollable laughter.

"It's not funny!" Esposito groused. "This is serious! We're friends, damnit! Bros! How the hell do people get this…twisted stuff from our friendship?"

"Oh come on, guys," Kate said between laughs. "It's just a couple of people having fun. So what?"

"So what? So what? They're writing porn about us Beckett! Can't we arrest them for defamation?" Ryan yelped in outrage.

"Grow up guys. It's a just a bunch of bored people looking to live their life vicariously through the two of you. Let them have their fun."

"Really? Well, if that's how you feel then I doubt you'd object to reading this," Esposito said viciously as Ryan fiddled with the computer a bit more before showing her the screen once again.

"What exactly is this? Caskett? What's that supposed to mean?" Kate asked, perplexed.

"Go on, continue reading."

This should so totally happen in real life!

"Oh my god, Castle," Detective Beckett moaned as Castle plundered her mouth. The two of them had been fighting off their sexual tension for years, but after their latest brush with death, they weren't able to deny it longer. "I want you so badly!"

Kate looked at the screen disbelievingly, unable to comprehend what she was reading. As she went over the text once more, she unconsciously balled her hands into fists and opened them again several time as a way to release the aggression the words brought up in her.

She took a deep breath, calming herself before she spoke. After all, it wouldn't do her any good to murder him before he sorted this out.

"CASTLE!"
