Disclaimer: I don't own Castle or the characters.

By the time Rick and Kate arrived back at the loft, it was well into the early hours of the morning. They'd got a break on their case and ended up catching the killer. It was no surprise that Jim had left and Martha had long gone to bed. They were both exhausted and couldn't wait to go to bed as well. What they saw when they entered their bedroom surprised them both.

Castle and Beckett were both sleeping in their bed which wasn't so surprising because it was easy to believe how that had occurred considering the late hour and the fact that they probably hadn't been able to leave if Jim had been their late. The unbelievable part was the fact that they must have migrated across the bed in the few hours that they'd been asleep and somehow Castle's arm had ended up around Beckett's waist and Beckett's back was pressed up against Castle's chest.

"Awww, look how cute we look," whispered Rick, trying not to laugh at the stunned look on Kate's face.

Kate couldn't believe that her younger self had not only willingly got into bed with Castle but his arm was also slung loosely over her waist and she was nestled back against his chest. But considering what they'd both been through in the past day, it was more understandable that she found comfort in his arms when she wouldn't have a few days ago. They past couple of days had changed both Beckett and Castle, Kate could tell, but she knew once they got back to their own time, things would go back to normal and Beckett would go back to at least pretending she didn't like Castle again.

"Shhh, you don't want to wake them," Kate whispered back, after getting over her initial shock. They both quietly grabbed a change of clothes, deciding to sleep in the guest room and not wake the other two. Both Rick and Kate knew that it would be interesting how Beckett and Castle would react to waking up so close together. They just hoped that they'd move apart during the night, which didn't happen of course.

Beckett woke slowly, feeling warm, comfortable and well rested. Castle's arm had tightened its hold during the night so when Beckett tried to move she couldn't. She realised something was around her waist, holding her close and that was when she felt movement behind her. Like a flash, the memories of last night came back to her and she realised where she was, and whose arm must be around her waist.

She tried moving again but to no avail, Castle's arm was too heavy around her. For a minute she considered going back to sleep, feeling comfortable wrapped in him and when she realised she was thinking that, she panicked, now just wanting to get out of his arms and for things to go back to normal.

"Castle," she whispered.

"Mmmmm..." came Castle's reply and she got a fright when she felt the sound ripple through his chest and through hers, the sound made right beside her ear.

"Castle, wake up," she whispered again.

"Beckett?" asked Castle groggily, finally coming back to the world of the conscious. He pulled Beckett even closer, snuggling into her back, still not fully awake apparently.

"Castle," Beckett whispered for the third and final time.

"What?" he asked smiling, finally realising where he was and who he was cuddled up to, he could certainly get used to this.

"You have to let go of me." She was acting annoyed but she couldn't help but find sleepy Castle cute. Damn her traitorous thoughts.

"Oh right, sorry," replied Castle, letting her go, realising that they weren't at that stage in their relationship yet. "Apparently I couldn't keep my hands to myself after all."

He was happy when she actually laughed then, glad he hadn't ruined the progress they'd made yesterday. He was glad to see that his joking had also removed any awkwardness from the situation as she went to get dressed.

He got up too to go and make breakfast again and was pleased to see her smiling when she exited the room shortly after to help him.

Rick checked before he went downstairs that Martha was gone. Luckily she was so they didn't have to worry about all four of them being together. He could hear movement downstairs but from the voices he could tell it was Castle and Beckett as Kate was still asleep in the guest room.

He was greeted by the same scene as yesterday morning, Castle had made breakfast for them all and Beckett was sitting there drinking coffee and as Castle gave her some food.

"Morning," said Rick, as he accepted breakfast.

"How was last night?" asked Castle, talking about both their current case and if there was any news on how they'd get home yet.

"Good, we caught the killer from our case and Mr Peterson says he should be able to get you two home in one piece, he'll let us know when the device is ready, he just needs time to make a few modifications," answered Rick, deciding not to bring up what he'd seen last night, not even to tease them. He figured if they woke up that way, they had sorted it out because things didn't seem awkward between them and if not, they didn't need to know.

"Great news guys," said Kate, as she came down the stairs, "looks like you two are going home."

"Oh, thank god," said Beckett, just wanting to be back in her time and for things to be back to the way they used to be.

"We're meeting him at the same warehouse in an hour so we better get going soon," replied Kate. She was relieved too, all this strangeness would be over soon.

An hour later, they were meeting Mr Peterson at the warehouse.

"Everything ready?" asked Rick, after they'd done greetings and introduced their past selves.

"It should be all ready to go. I made some modifications meaning that I can control where you end up without having to go myself. And if I got the calculations correct, you'll end up in the exact place you left, give or take a day," Mr Peterson answered. He had been working all night and everything seemed to be working properly.

"We won't remember, will we?" asked Beckett, slightly disappointed but also relieved she wouldn't remember the past day.

"Those two didn't," he said, pointing to Rick and Kate, "so hopefully you two won't either if the modifications I made work. You should end up where you left and with no memories."

Beckett checked her pocket, just to make sure she had the note telling herself not to tell Castle to leave. She'd written it this morning when he'd gone to make breakfast. She wasn't taking any chances, she wanted to make sure she didn't let him go.

They said their goodbyes then, Castle and Rick shaking hands and Beckett and Kate hugging.

"Good luck," whispered Kate into Beckett's ear to which Beckett replied, "You too."

"You guys ready?" asked Mr Peterson, once everyone had finished saying goodbye.

"Yes," said Castle at the same time as Beckett said "wait" and then she turned and kissed Castle. It only lasted a few seconds and was a simple press of the lips but it was so much better than both Beckett and Castle had imagined, not that Beckett had ever imagined kissing Castle of course. Castle was too stunned to do anything but stare at her.

"I just wanted to know what that felt like, just once, before things go back to how they were," said Beckett to Castle before she turned and addressed everyone, "okay, we're ready now."

Kate and Rick looked on shocked, Kate being shocked that her younger self had actually kissed him and Rick thinking about how that would have been their first official kiss even if neither of them remembered it.

Castle couldn't believe that had just happened, had Beckett really just kissed him? He couldn't stop smiling as Mr Peterson prepared to press the button that would send them home. Beckett couldn't help but smile as well as she replayed what had just happened in her head and that was her last thought as Mr Peterson hit the button and everything went black.

"Thank god we found you, what happened? You've been missing for two days," said Esposito, worry evident in his voice since Castle and Beckett had seemingly vanished off the face of the earth.

"Two days? How is that even possible?" replied Beckett as Ryan and Esposito walked them out of the warehouse to where their cars were parked outside.

No one could figure out what had happened. When they'd searched this warehouse earlier they'd found their phones and the file that said that the victim's wife was the murderer but there was no Beckett or Castle. It was luck that they checked this warehouse out again. They'd run out of other options so came back here looking for more clues and had luckily found them instead.

"Alexis and my mother must be worried sick," said Castle once they were outside, frantically searching for his cell phone.

Esposito let him borrow his, since Castle's was back at the precinct and once Castle had called his family, assuring them that he was fine, he and Beckett headed back to the precinct to see if they could figure out what was going on.

Several hours later, all paperwork done, they decided to call it a day. Esposito and Ryan had arrested the wife after confirming the facts in the file so that case was now closed. No one had any idea what had happened and it didn't look like they were going to figure it out, not now anyway, so they all left to get some rest and hopefully they'd get some answers tomorrow.

Beckett didn't know what to think about the past 48 hours, she had no idea what had happened and no matter how hard she tried, she couldn't remember the events of the previous two days. The only clue she had was a note she'd found and she didn't know what to make of it. All it said was Don't let Castle go. You need him. She had been thinking about talking to the captain or even possibly the mayor to see if Castle could stop following her and she wondered if the note had something to do with that. It was written in her own handwriting so maybe something had happened over the past two days that had changed her mind about Castle leaving and perhaps she should trust herself and give Castle another chance.

She hoped one day she'd find out what the note meant and what had actually happened but until then, she'd keep living life like normal. Although, maybe she'd give Castle more of a chance now. She didn't know under what circumstances she would have written something like that but if she knew she was going to forget, maybe this was a way to make sure Castle stayed in her life. She went to sleep that night thinking about Castle and wondering what the future and working with him would bring.

And that's the end! I think this has been the most fun and challenging fic I've written so far so thanks to you all for taking the time to read it.
