Disclaimers: No I don't own 'Castle.' If I did, Castle would've hugged Beckett at the end of 'Disciple.'

Summary: Filler for the bathroom scene in 'Valkyrie.' That means an M-rating. Contains spoilers for episode.

A/N #1: I'm using 'Come Monday' by Jimmy Buffett for this chapter.

Chapter 12: Trying to Reconnect

Headin' up to San Francisco

For the Labor Day weekend show

I got my hush puppies on

I guess I never was meant for glitter rock 'n' roll

And honey, I didn't know

That I'd be missin' you so

Come Monday

It'll be all right

Come Monday

I'll be holdin' ya tight

I spent four lonely days in a brown L.A. haze

And I just want you back by my side

It seemed like an endless flight from one coast to another. Rick Castle sat in first class, toying with his glass of Scotch as he thought about what he had waiting for him when he got back home. Alexis wasn't due back from Costa Rica for another week, and Kate was flying down later that afternoon to spend the weekend with him.

He smiled as his mind went to thoughts of his fiancée. She'd been in D.C. for two months and they'd only been able to see each other briefly once during that time. Back at the beginning of the summer. She'd miraculously been able to get four days off during her intense training with the FBI and they'd spent it at Chesapeake Bay, walking on the beach and making love in front of a roaring fireplace in the little cottage he'd rented for them. Then she'd had to go back to work and he had this grueling book tour. They talked every day, but talking to her via electronic technology wasn't the same as holding her and kissing her and touching her. He could close his eyes and remember how she smelled and how she tasted when her lips and tongue met with his, how her skin felt under his fingertips.

He smiled when he thought of the souvenirs he'd bought her. Knowing how she loved to sleep in his t-shirts, he'd bought her several oversized t-shirts to sleep in. Of course they served a dual purpose. Oversized t-shirts made her more easily accessible to him when he sought her out in the middle of the night. He looked at his watch. Another hour until the plane landed at JFK. Soon, he'd be in his own home, sleeping in his own bed, and eating his own food without having to listen to the nagging voice of his publisher/ex-wife in his ear.

While waiting in baggage claim later, he sent Kate a quick text. 'I just landed back home in NYC. I can't wait to see u later. ILY.'

But when he walked into the loft just over an hour later, he was hit with one hell of a shock. Alexis was home early and she hadn't come home alone. She'd brought a boy with her. A boy who looked like the son of rocker John Oates. A boy who'd been sharing his daughter's bed while he was gone by the looks of it. And then the proverbial icing on the cake had been Kate calling to tell him that she had to cancel their plans because she'd just had a huge case dropped in her lap.

Yes, it's been quite a summer

Rent-a-cars and westbound trains

And now you're off on vacation

Something you tried to explain

And darlin', since I love you so

That's the reason I just let you go

Come Monday

It'll be all right

Come Monday

I'll be holdin' ya tight

I spent four lonely days in a brown L.A. haze

And I just want you back by my side

Castle sat in his office pouting as he thought about the phone call from Kate. When he'd asked her to marry him in May, she'd been worried that they wouldn't be able to make this long distance thing work. He'd assured her that they could and that they would. But it wasn't turning out to be as easy as it had looked on paper. Take this huge case, for example. If she were still in New York, they could build theory together. But, since she'd joined this task force, it was rare that she could even talk about her cases, let alone use him to build theory.

"You do realize that she has to sleep some time," he looked up to find his mother standing in the doorway. "Katherine. She has to sleep at some point. All work and no play, you know? And, the last time I checked, the plane does fly both ways."

"You're right," he jumped to his feet, running over and kissing his mother on the cheek. "Let me just grab my bag! Can you let Alexis know—"

"Go!" Martha shooed him out the door.

Kate was miserable after ending the call with Castle. She'd been looking forward to seeing him in the flesh. She wanted his help decorating the condo. She wanted to wake up in the morning and cuddle up with him. She hadn't been able to touch him since late June when they'd gone to Chesapeake Bay for a long weekend. Since then, her newly engaged life had consisted of long phone calls and video chats.

She liked her new job with the FBI task force, but she was so lonely. She was low man on the totem pole and most of her new colleagues had no problem reminding her of that fact. Even earlier that day, she'd failed a training exercise miserably, reenacting a moment that cut a little too close to home. At least this time the blood on her chest was fake and not the real thing.

"I'm sorry if your plans are being ruined," her new partner, Rachel McCord, told her. "But, you're a fed now. So, you might as well get used to that little fact of life. Maybe if we get things wrapped up, you can still squeeze in a little time with your boyfriend."

Kate didn't want to 'squeeze' in a little time with Castle. She missed sitting at her new desk and not seeing him sitting there, playing Angry Birds on his phone or staring at her while she did paperwork. "I guess that we should get to work then," she said, looking at McCord.

***CCC***

There was a flight that left New York for Reagan National in D.C. every hour on the hour. Castle arrived in the nation's capital late that afternoon. He walked out and hailed a cab, giving the driver the address of Beckett's condo. Punching in the gate code once they arrived, the cabbie dropped him off at the front door. After paying the driver, Castle pulled out the key that Kate had given him and entered the condo.

He noticed packing boxes still stacked by one wall. He took his bag to the bedroom and put it at the foot of the bed. He frowned as he couldn't help but notice that she hadn't done any more unpacking than she had when he'd last seen the apartment during his visit earlier in the summer. She'd placed a few framed photographs out on a knick-knack shelf in her living room, but that seemed to be the extent of her decorating. He smiled as he looked at the pictures. Besides the ones of her father and mother, she'd also placed one of the two of them that had been taken during their trip to Chesapeake Bay.

He walked over to the refrigerator and opened it, peering inside. Except for a container of milk, she had no other food. He hoped that he wouldn't have to wait too long for her to come home. He'd missed her terribly.

He had dozed off in a large comfortable armchair in her living room when he heard her key in the front door. He squinted as he looked at his watch. It was after nine. He watched as she placed her purse and her jacket down before walking into the bathroom and turning on the light. He stood up, watching her unbutton her blouse. He slowly moved toward her, but a creaking floorboard caused her to whirl around, gun in hand. "Hey, would you mind taking that off first before you shoot me?" He asked, hands raised in self-defense.

"Cas . . . Castle?" She asked in shock, slowly lowering her glock.

"I know that I promised to respect your job, but I just couldn't go one more minute without seeing you," he walked into the bathroom, where he stopped next to her.

Her smile was joyous, just as it had been the last time they'd been together. "You . . . you shouldn't have come here."

"So, do you want me to leave?"

"Oh, immediately," she grabbed his face and lunged herself at him, her lips searing and urgent on his, as she made an attempt to climb up his body, first with her arms and then by bringing her leg up over his hip. "Oh, god," she moaned into his mouth as their hands frantically roamed each other's clothed bodies.

I can't help it, honey

You're that much a part of me now

Remember that night in Montana?

When we said there'd be no room for doubt?

I hope you're enjoyin' the scenery

I know that it's pretty up there

We can go hikin' on Tuesday

With you, I'd walk anywhere

California has worn me quite thin

I just can't wait to see you again

Castle finished unbuttoning Kate's shirt, pulling it off of her shoulders as she reluctantly released her ironclad grip on him so he could pull it off and let it flutter to the floor. He then let his hands roam her back and sides before he reached up to unclasp the front clasp on her bra, pulling it off of her shoulders. "Fuck, Castle," she growled against his mouth when she once again was forced to let go of him.

"I'm trying to get you naked, Beckett," he growled back.

She gave a small hop, wrapping her arms around his neck and her legs around his waist. "Take me to the bedroom," she smiled before kissing him once again.

He grabbed her ass to hold her tighter to him as he walked them both to Kate's bedroom before setting her down on her bed. He then removed her shoes, socks, and slacks, leaving her clad in dark blue panties. She bit her lip as she eyed the undeniable bulge in his pants. She then reached out, impatiently unbuckling his belt, and then undoing his pants, tugging them down his legs. She then reached into his boxers, wrapping her hand around his arousal, brushing her thumb over his tip as he thrust into her hand. After a few minutes she released him and hooked her fingers into the sides of his boxers and yanked them off of him. He stepped out of them when they pooled at his feet, kicking them to one side.

He then settled himself over her body, his lips hungry on hers, his tongue exploring the warm recesses of her mouth. "Castle," she let out a whimper when he left her mouth to kiss the column of her long neck, nipping gently at her pulse point, causing her to jump against him. She shifted her pelvis against his erection, earning her an answering growl from Castle. But, at least he seemed to get the hint, since she instantly felt his fingers swirling through her wetness, brushing against her clit, setting her further aflame. "Castle, get inside of me. Now!"

He rose up to give her an impish grin before he yanked her panties off of her and entered her with a savage thrust that made her cry out against him. She clung to him as he moved hard and deep inside of her, their cries reverberating off of the walls of the small bedroom. She wrapped her legs around his waist, changing the angle and depth of his penetration, causing her to feel him everywhere. She could feel the tension coiling deep inside of her. But she wanted more. Pushing at him, she managed to roll them over without breaking their connection,

Castle's hands reached up to pinch and roll her erect nipples between his thumb and forefingers as she moved on top of him, her breaths coming in rapid gusts as her orgasm started. He felt her tighten and flutter around him as she gave a loud keening cry. He brought her down so that his mouth could latch onto hers as he thrust up into her, feeling his own release bearing down on him. "Kate, come for me again," he whispered against her lips as he reached his fingers down, pressing hard against her swollen nub as she jerked against him. "Come on, baby."

She reached her hand down, placing it over his as they worked together. "Harder, Castle! Shit! I'm almost there! Oh, God!" She screamed out, as her fingers stilled over his, but she could feel his fingers continuing to work on her wet, swollen flesh. "No more, Castle! Too . . . too sensitive."

She collapsed on his chest as she felt him come deep inside of her. She sighed contentedly at the feeling of his large, warm hands caressing her bare back. She whimpered in disappointment when he slowly rolled them so that they were laying side by side, her body bereft at the loss of their intimate connection. He planted soft, open mouth kisses to her shoulder and neck as they began to slowly come back to planet earth. "I missed you, so much."

"I missed you, too. But, you're lucky that I didn't shoot you."

"Did you solve your case?" He kissed her hair.

"No. I have to go in early in the morning. I had the day from hell, Castle," she wrapped her body tighter into his. "I'm glad you came."

Come Monday

It'll be all right

Come Monday

I'll be holdin' ya tight

I spent four lonely days in a brown L.A. haze

And I just want you back by my side
