A/N: Sorry this update took so long. I started writing it and then got sucked into another love scene. It will show up in the next chapter or so. Hope you like!

"Meredith." She looked at the redhead in shock and took a deep breath before turning to the blonde sitting next to her. "Gina." She looked down at herself. "Oh..."

Kate finger-brushed her hair nervously. "What...uh... What are you... both doing here?" She shifted, doing her best to use the counter as a shield, her hands making the coffee on autopilot.

"Well," Gina crossed her legs slowly, leaning back like she was a guest there for tea.

Beckett felt her hackles start to rise.

"I've been trying to get a hold of Rick for the last two weeks. He's overdue on his last three chapters. Imagine my joy to hear he went off to LA... with you ...and never returned any of my calls. When I heard he was back, and still not answering my calls, I decided to come over and make sure he was ok." One eyebrow raised sarcastically. "He seems to be doing ok."

Kate opened her mouth to retort but Meredith beat her to it. "And it's my week with Alexis." The red head smiled sweetly, showing off every one of her crocodile teeth. "Imagine my surprise when I ran into Gina in the elevator. I didn't see the harm in letting her in. At least until I realized Alexis wasn't here. So I went looking for Rick. Then I opened his bedroom door and found you... naked... sprawled across my husband."

"Ex."

Meredith blinked. "I beg your pardon?"

"Ex." Kate growled. She had had enough. Of the three women in this room she had the only legitimate (or so) reason for being here. "You seem to keep forgetting that he is your EX husband." Her brow furrowed in anger. "Both of you."

Meredith's smile disappeared. She looked at the detective pointedly. "You should be careful what you borrow from him. He was always a little possessive about his Green Lantern crap."

Kate looked down, sucking in a breath when she recognized the symbol on her chest. It was his favorite, the one he wore on every day off. The one he saved from the trash bin more than once when Alexis was washing clothes.

Before she could answer, the door to Castle's study opened and they all froze.

He walked out with his robe open, gloriously naked underneath; indicating that he had no idea they weren't alone. He was scratching gently under his eyepatch as he stumbled towards the kitchen. When he saw Kate and the coffee his grin was huge. "You read my mind."

He didn't stop moving until he was right up against her, slipping one hand around her waist to turn her as his other went to her cheek. He stopped for a moment and looked her up and down. "Damn."

Beckett blinked nervously. "What?"

Rick smiled as he leaned down to capture her lips briefly. "Have I ever told you how incredible you look in my clothes?"

Smiling widely, Kate closed the small distance between them, groaning when he wrapped a hand in her hair to pull her closer. A moment later it was gone, gliding up under her shirt as his other hand opened his robe more widely. Then he pulled her against him and she groaned.

"Rick..." She tried to interrupt his intent but she so loved how he felt. "Rick..."

He had just slammed her back against the counter when it happened.

"AHEM!"

Castle pulled back, blinking through a lust induced haze until his eyes landed on the two women sitting on his couch. With a loud squeak he ducked behind Beckett, using her to block their view as he hastily tied his robe.

"Kitten!" Meredith's eyes widened as she stood and rushed to his side, brushing Beckett aside roughly. She rubbed up against him as her fingers went to the patch covering his eye. "What has she done to you now?"

He pulled back quickly, putting some much needed space between them. "It's nothing! I'm fine. Just... got into a fight."

"A fight?" Gina took a seat at the bar. She smirked. "Can I guess what it was about?"

"Richard Castle! You are too old to be getting in fist fights. What would your daughter think?" Meredith glared at him.

"Uh... that it's pretty cool?" Rick grabbed his coffee mug and took a long drink. "On another note... what are you doing here?"

Gina shrugged. "You owe me pages."

Castle sighed. "I know I do. I sent them to you last night. You should check your email before embarking on terrorist activities."

Gina smiled sardonically. Standing, she went to the couch and picked up her bag and coat. "They better be there." She turned to Kate, looking her up and down speculatively before smirking and walking out the door.

Meredith was not going to be so easy.

"So," The redhead turned on them as soon as the door closed. "Am I to assume that you chased our daughter out of her own home so that you could have playtime with your... Toy-friend?" She looked at Kate with such disdain that the detective actually took a step forward, only stopping when Castle's arm wrapped her middle and pulled her back.

The writer's voice was cold when he answered. "Her grandmother wanted to take her for a spa day at the Waldorf." He pulled Kate tighter against him, almost hugging her to him. "It had nothing to do with us."

"Right." Meredith snorted.

"In any event," Castle continued. "She isn't here. She'll be home later today. Go back to your hotel and I will tell her to call you as soon as she gets in."

His ex-wife blinked. "Hotel?"

Kate's muscles tensed and he stepped in front of her. "No, Meredith."

The ginger haired woman slid closer, running her finger down his cheek. "You know I can share... if I have to."

"I won't." Becket growled at the impudent woman.

"I don't think it's up to you." Meredith sneered.

"But it is up to me." Castle pulled away from Kate, taking his ex-wife by the arm. "I'll show you out."

The detectives mouth fell open; her eyebrows knitting together in anger as she took one step forward... only to stop when her partner held up a hand. Seething, she turned back to the kitchen, trying not to count the seconds that Castle was spending with his ex-wife; the mother of his daughter...

After what seemed like an eternity, Rick returned to the kitchen. He walked up close to her, invading her personal space. "I'm sorry." He whispered.

But it was beyond apologies now. "And you think that makes it alright?" Beckett shrugged off the hand he tried to place on her arm. "That your ex-wife can just waltz in here anytime she likes?

Kate stared at him hard. Surprised when he smiled at her and took her hand; pressing something into it. "She can't do that anymore."

She looked down at her palm; her breath catching when she saw what he had put there.

It was a key.

"Castle?" She looked up at him in wonder.

"I made her give it back." He smiled. "From now on she can knock... like anyone else."

Kate melted against him, her hand curling tightly around the key as his arms wrapped around her.

"I love that you're jealous." He stroked her cheek gently. "But you don't have to worry. You are my density."

Kate blinked at him.

"Michael J. Fox? Back to the Future?" He sighed. "Seriously, do you not watch cable?

A/N #2: Someone sent me a review that said it was laughable that a woman would wear a man's clothes. That it never happened. O.o. Aside from personal experience, and the experience of friends I queried... I would tell this person to reference Castle Season 5, Episode 1. When they pretty much made it canon that Beckett would do just that.

I may be in a different timeline, but the characters are still the same. ;)

Thanks for the support! And if you have time please review!
