Disclaimer- I don't own Castle or anything associated with it...

A/N- Thanks to Joanna and Janna for the help with this one. Here is the sequel to You Can't Give Up, so if you haven't read it...give that a read first :) but I added the last part of that story below as a refresher ...I have the story outlined so hopefully I can have this updated fairly quick, but sometimes stories move in different directions than I originally planned. So I hope you enjoy the ride!

If You Want The Happy Ending

"Well maybe it is a sign. A sign that ours is a great love story. Cause what's a great love story without obstacles to overcome? Every fairy tale has them. Terrible trials that only the worthy can transcend but you can't give up. That's the deal. We want the happy ending, we can't give up." - Castle

(From the Ending of "You Can't Give Up")

"Hey…so I have news…" Esposito started hesitantly and then paused. Kate absent-mindedly balanced her cell between her ear and shoulder so she could use both hands to put away the ice cream. She looked over at Castle who seemed to be transfixed with the envelope.

"Open it…" She whispered to him. "Sorry Javi, what is it."

"Beckett, we got the results back from the lab about Tyson. Without a doubt, that body was not him…."

"What!" Her hands started to shake and the room started to spin. She quickly found a stool at the kitchen bar to sit down on. "Are you sure?"

"Yeah, positive. Looks like this is another Dr. Nieman designer clone…" Then it hit her, what Tyson said in that room. Tyson had her help him with some additional items…this was it. He had her make someone look like him. A shiver ran through her body without her knowledge. The other shoe…the one both her and Castle were waiting to drop….it came crashing down.

"He was wearing the same clothes, Espo…that was the same man. I could've sworn it."

"It very well could've been the same person, Beckett. The clothes he was wearing had Castle's blood on them…unfortunately…he could be anywhere, and at this point, he could look like anyone…"

"No…no this can't be happening…" Her stomach twisted in a knot and she needed to get to the closest bathroom. The phone slipped from her hand and she sprinted to the bathroom. She heard Castle stumble after her, as she proceeded to empty the contents of her stomach into the bowl. He bent down gently to rub her back and placed a kiss into her curly brown hair that he brushed out of her face. "It wasn't him…he's still out there…" She choked back a sob as she turned toward the concerned look on her fiancé's face.

"I know…" His face fell as he held up the brown envelope that hadn't left his grasp since walking through the door.

"You know? How?" Slowly he opened up the envelope and pulled out a single piece of paper. Beckett wiped off her mouth and sat down onto the floor.

"Because of this…" His eyes closed as he handed her the paper. Her ultrasound picture. She frantically looked up at Castle, before she turned the image over where she noticed some words scribbled on the back…

"Congrats to Mom and Dad…See you soon…T"

Oh God…

Chapter One

A month had passed since they'd been home. A month had passed without a clue, without a sign...the trail had run cold. Not that there was much of a trail to begin with. As typical with 3XK, if he didn't want to be found, he made sure to cover his tracks. The only partial lead they had was the package left at their front door, but as with everything else...it was a dead end. Twenty dollars and a handshake was the only agreement between the courier and Tyson. After bringing the man in for questioning, it was obvious that he was just an innocent person who was just at the wrong place and took money from the wrong person.

Unfortunately, due to the lack of leads, Gates had officially put this case on the back-burner. Their safety on the backburner… Kate knew that she didn't mean it as a personal attack. Hell, Gates had been nothing but supportive during the entire ordeal. It wasn't personal…it was her job as Captain. She had to be the boss and make the decisions. So as much as Beckett wanted to be angry, she really couldn't.

So they set up shop at the loft. They used Castle's smart board as a make shift murder board and they worked on the case when they could. From the outside looking in, they seemed to have it all together… In all actuality, they were barely making it through the day to day.

6 A.M., she internally groaned to herself, rolled over to shut off her alarm and rubbed her face to try and bring awareness to her system. She was absolutely exhausted…the type of tired where she could sleep for weeks and it still wasn't enough. Her doctor told her that this was all normal for the first trimester, but his words didn't help…even his guarantee of "the second trimester is usually better" didn't hold much stock in her books. Being that today was the first day of her second trimester; she wasn't holding her breath. Lightly laying a hand on her still flat stomach, she said a slight prayer that things would be better by the time their little person arrived.

Turning to her side, she noticed that Castle was nowhere to be seen and his side of the bed barely looked slept in. This was going to be a very long day…she sighed and walked off in search of her fiancé. Sure enough, he was exactly where he had spent most nights. Sleeping while sitting up on the couch, facing the door…keeping guard. It broke her heart to see how hard he was taking this entire situation. She's the cop, yet he single-handedly felt that it was his responsibility to protect his family. In an effort to appease him, she even suggested hiring private security, but his paranoia of Tyson could be anyone or anywhere, left that fight dead in the water.

Walking up to him, she ran her fingers through his hair and kissed his forehead lightly. The love she felt for this man was something she never thought possible, and because of that, his torment and anguish was also her own. All the physical signs of his captivity and battery had healed to the naked eye, and his routine physical therapy was a huge help with some of the more serious issues. If only that solved all the problems...if only the physical was the only bridge to cross... He was talking to someone, which was a step in the right direction, but then the nightmares started. Nightmares that in the end sent him to stay on the couch each night so he could be on alert without keeping her up. Nightmares that left him to be a shell of the man she loves; nightmares that have turned him into a walking zombie. He's really trying, she can tell, but he's told her in detail his fears. The scenes that play out in his head, the feeling of dread that he can't shake. When Tyson left that threat on the ultrasound picture, that's when Castle completely unraveled.

"Babe…" She brushed her hand down the side of his face and placed another kiss onto his lips. "Castle…" His eyes fluttered open, but his expression was glazed over. "Hey…you should try and get some real rest…in our bed. I need to get ready for work, but please try and get some sleep."

"What….um no…I should go in with you…" She smiled at him and shook her head, while he tried to snap awareness into his body.

"No, Castle. I'm perfectly capable of going to work alone. I'll be fine, plus you have an appointment with Dr. Burke today." His eyes lowered to his hands and his shoulders dropped in defeat. She hated seeing him like this, but hopefully this change in doctors will help.

"True, but I don't want you out there. Not when he could…" She cut his words off with another kiss. The early morning hour had left him so vulnerable; more open than the façade he plays off during the day.

"I will be careful. Plus, I carry a gun." Castle gave her a small smile and she knew it was one that he forced.

"Then the world doesn't stand a chance again you…" He smirked at her, with the empty words. Words she knew were just for her benefit and that he didn't truly believe them. Sure he loved her and still thought she was amazing at her job, but he had previously told her that he felt like evil was lurking; waiting to take his happiness from him.

It was a slow day at the precinct. Days like today, she wanted nothing more that to be at the loft working on their case. The only case that mattered to her at this point; the only case that would help Castle... Her Castle. The man she fell in love with, the man who made her believe in happy endings and reminded her that she couldn't give up. Tyson robbed her of that man for now, but hopefully he was not gone forever. This was just a brief hiatus on the road to healing.

Her time with Dr. Burke had been productive; each session broke down her fears for Castle, for herself, for the pregnancy. He helped her work through it to the point that she was okay to go to work without Castle. The fear that if she left him alone, he would disappear, were now only in the back of her mind instead of the forefront. Castle, however, did not have the same luck with his original therapist. Even though Dr. Clain came highly recommended, the manner that he conducted his sessions didn't mesh with her fiancé's personality and when the nightmares started, Kate knew that something had to change. Dr. Burke agreed to see Castle as a favor to her with the mutual understanding that the individual sessions would remain private.

Snapping back into the present, she looked at her father's watch. 3 P.M. His appointment with Dr. Burke should've been done an hour ago. Panic quickly started to rise in her chest, before her practical, analytic side took over. Maybe the session was so productive that Castle went home with a clearer mind and he was finally getting some much needed rest. The story was logical, but the idea didn't ease all the worry within her. Kate picked up her cell phone and hit the Castle's saved contact number. After a couple rings, his voicemail message picked up. Great. Calling him was supposed to help the nagging feeling in her body, not make it worse.

"Hey guys…" she called over to Ryan and Esposito at their respective desks. "I'm going to take the rest of the day off unless we catch a case. Call me if something comes up."

"Everything all right?" Esposito gave her a concerned look. The two of them have been a great support system to her and Castle, but she hated burdening them with anymore then she already did.

"Yes…I think. I just want to get home to see how Castle's appointment went. Make sure he's okay…" she quickly spoke; trying to avoid further questions. They both knew about the baby, after the incident with her ultrasound picture. Originally she hated that she had to share their news before they were ready, but in times like these…it was much easier for her to leave work. Her partners were cutting her some slack…

"Okay, Beckett. But if you need anything, you better let us know." She nodded to her partners, thanked them and hustled to the elevator. He was just sleeping, that had to be the reason.

"Castle?" Beckett called out to him as she walked into the loft. Looking around, things were moved around a bit, and some random bouquets of roses were adorning miscellaneous tables and shelves. What in the world was going on? "Castle? What is all this?"

He walked out of his office, looked at her, and his eyes quickly widened. "Kate, what are you doing here? Home? Now?" His voice held a nervous quality, only made more suspicious sounding by the string of questions. Normally before the abduction, he couldn't wait until she got home and on days that she came home early to surprise him, he'd rush to see her. Nervous was never the reaction she received, until now.

"Um..." Shaking her head out of her mental fog, she walked closer to Castle. "Did everything go okay with Dr. Burke today?" He smiled at her. His smile…the genuine smile that she had come to love.

"It was good. Much better than my other sessions. Our talk is actually why I'm rushing around. I wanted to surprise you, but you came home early…" Castle reached over to her and wrapped his arms around her waist. A small sign of relief fell from her lips. He seemed happy and while she knew this was most likely a temporary euphoria, she was going to enjoy it while it lasted.

She rested her head against his chest and softly laughed. "What would you possibly need to surprise me for?"

"Today Dr. Burke asked me about the fears I was having. He asked what things bothered me the most about what happened to us. We discussed some of these at length and separated things I could control and things that I couldn't. If I could control or fix the issue, then maybe that would slowly allow me to accept the rest that I can't change." She stared up at his face, confused as ever. The blue in his eyes sparkled when he continued to explain his revelations. "One of my main issues was Tyson stealing our wedding day. That currently, over a month later, we still aren't married. And Kate, I don't want to wait anymore. I don't want to wait for the next disaster to strike…." Castle pulled back from their embrace to move down onto his knee. She smiled down at him and fidgeted with her engagement ring that hasn't left her hand since the ordeal. "Katherine Beckett, I love you more than life itself. I don't want to wait anymore. Will you marry me, tomorrow?"

A gasp escaped her lips. Wait, what? "Rick…"
