A/N: Things that come upa t 2 am are never good. This is an exemple of that. I honestly don't know how it wrote itself, but whatever, you know? Hope you like it Also, I do not own Castle or anything related to it.

She sat on the couch looking through the window. The city was calm at 4 am, even though it was 'the city that never sleeps'. Thinking about it, she was a bit like her city: like her New York, she barely slept, and whenever she did it wasn't in peace. The city where she was born, the city where she grew up. The city where she had the best memories of her mother, and the worst. When her mother died, she had considered moving to another place, another town. A place far enough for her to forget about everything that had happened. But, if she already felt uncomfortable in a city where she didn't have her mother, how could she ever live in a city where she wouldn't have anyone but herself?

She was never one to have many friends - except for her wild phase, when she was the popular high school girl that everyone wanted to be, the one who got drunk, did drugs and slept around. But, when she actually opened her eyes and saw that that wasn't an appropriate lifestyle, everyone forgot her - the ones who swore to be her best friends for life turned their back on her, and the ones who told her they loved her just wanted to fuck her. From highschool she only had one or two real friends, Madi and Audrey, and they barely talked anymore. Busy lives, busy times. When she got into college she started talking to one nice girl, but they had lost contact after Kate got into the Academy. There, at the academy, she made real friends she knew she could count on. Her little team was far from perfect, but it was perfectly flawed.

And that brought her back to New York. Her favorite city in the world. Where would she be if she had actually moved when her mother died? She couldn't imagine herself elsewhere. If she wasn't in New York, she wouldn't be working at the 12th. She wouldn't have met Lanie, her very own personal stylist; she would have never met Espo, her big brother; and she wouldn't have met Ryan. She would have lost contact with Capt Montgomery. And she'd probably never have shot her mother's killer. Or solved the case.

She would have, though, met Richard Castle anyway. Kate smiled at the thought of him. Of course she'd have met him, even if it was only at one of his signings. She had loved his books since her mother died, and as every other author she loved, she would have found a way to, at least, tell him her name was Kate and she loved his books, letting him know that - even though he probably wouldn't have cared. If she wasn't in New York though, she would have never had the chance to work with him. To be followed by him. To be his muse. Who would've thought…?

"Hey there Batgirl"

"Batwoman, please. I am old enough not to be called a girl, Castle"

"Sorry, Batwoman. What are you doing up at this…What time is it? 4.30 am?"

"I couldn't sleep"

"Another nightmare?"

"No, no. Those have stopped, I've told you"

"I'm glad."

"And you? What are you doing up?"

"My bed was too cold and empty, it's hard to sleep without you there"

Kate smiled at his sleepy eyes and messy hair. Even at 4.30 am and as snoozy as he was, he was still the most gorgeous man on Earth.

"C'mon Batman, let's get you into the batcave"

"Only if Batwoman comes with me to the batbed"

"Always"
