AN: So I am actually almost done all of my work, and now since I'm caught up on all my current shows and it's the weekend so here I am, writing on a Friday night. I found this prompt randomly, and then I found a cute little idea that fit it, it may not be my best but I wrote it in one night and it turned out way longer then I planned, so here you go

P.S. I would not recommend crawling into a cabinet and jumping out, so don't blame me if you decide to try it during laser tag or for any other reason.
Xoxo Emily

Prompt: A character's fondest wish come true

This was not how she had imagined it.

Sure, it was amazing, and her even her tipsy brain knew something was off, but she didn't realize that she had forgotten just one thing.

Castle's immaturity.

*earlier that day*
"Beckett, are you done writing your report? All this food is not going to eat itself"
Caste flopped down into her chair at the table, surveying all the food he had cooked. The whole table was covered with every kind of food you could imagine, and he had worked hard on all of it.

"Give me a second, it smells amazing– oh my god Castle, are we having the army over for dinner? We can't possibly eat all of that-"

Castle rolled his eyes shoved a plate of food at her.

"And that's why they invented the refrigerator Beckett. I just felt like cooking a bunch I guess. So eat, and maybe we can play laser tag later"

Beckett thought for a moment, she had work but the temptation of crushing Castle was almost too much. Beckett was undefeated so far in the Castle house arena, and she wouldn't mind extending her streak.

"Fine, but be prepared to get crushed. Just because you're my husband doesn't mean I'll go easy on you"

Castle clapped his hands in glee, and began to clear the table. He knew all the extra food would come in handy later, so he made sure to carefully pack away everything. The laser tag bribe may not have been the best idea, but he had time to kill and needed to go over his plan anyway…..

"500-0, I would have thought you'd know your house better then me" Beckett's teasing tone came from the living room, where she had made the killshot."

"HEY. IT'S NOT MY FAULT YOU CAN CURL UP INTO CUPBOARDS SO EASILY…..How can you even jump out of those and shoot at the same time?!"

Beckett just smirked and stretched out on the couch, enjoying the pout on Castle's face.

"Let's just say I'm pretty flexible…."

Castle's eyes grew wide and he dropped his laser gun, as much as he wanted to take Beckett up on that, there was stuff to do. His willpower was strong enough...right?

It was all Beckett could do to hold in her laughter, but he focused on his plan. Tonight was gonna be special and there was so many little details to go over.

Castle could hear Beckett typing away in her office, and took the opportunity to sneak into their bedroom unnoticed. It wasn't exactly how he imagined marriage were suppose to be like, but his relationship with Beckett hadn't exactly been normal either. He stole the biggest blanket he could find, Beckett's favorite pillows, some pajamas, the new scented candles she had just bought, then threw it into a bag. You could never be too careful..

It was 9pm and Castle knew it was time to set the plan in motion.

"Beckett, I'm just going to run to the store and get some more food, ok?"

Beckett's head popped out from her office, wondering why Castle would be going out so late, but too involved in her work to pay much attention to it.

"Mmmmmk, don't stay out too late. I was thinking we could order Thai Food at 10, that okay with you?"

Castle paused for a moment, deciding what to tell her.

"Well, I had other plans for dinner, I was hoping we could go out….?"

Beckett tilted her head, confusion written all over her face

"Are you sure? I'm kinda tired and I was kinda hoping we could just cuddle on the couch and watch a movie…"

A pang of guilt shot through Castle, but he pushed it aside and reminded himself of all the work he had put into tonight. He gave Beckett his puppy eyes, knowing she couldn't resist.

"…..Fine, but tomorrow we are SO staying in all day, got it?"

Castle broke into a grin and ran over to kiss Beckett

"I promise I'll make it totally worth it, and we won't set foot outside this house tomorrow!"

He grabbed his phone and waited til Beckett was back to typing before grabbing his bag with everything he would need and a basket with all the left over food from lunch.

With the food in an ice box in the trunk and the bag in the passenger seat,, he dialed Ryan's number and waited for an answer.

"Hello?"

"Hey Ryan, I've got everything ready, are you there yet?"

"Hang on, I'm almost there. Do you have he Knicks ticket ready?"

"Yes Ryan, I want everything to go perfectly and keep it a surprise so if you don't tell Espo or Jenny I'll let you borrow my Ferrari for a day"

"You got yourself a deal Castle, I won't breath a word to anyone"

Castle ended the call and started driving, going through everything in his mind and praying that all would go smoothly.
He pulled up to the park and parked his car. He grabbed the bag, basket, and icebox, then scanned the park for Ryan. Spotting him in a small gathering near the lake, he strolled over as quick as he could while balancing all the things he was holding.

"Wow, is there anything you didn't bring?!"

Castle set everything down, and glared at Ryan

"I put a lot of work into this and I need it to be perfect. Just set everything up and call me when it's done, ok?"

He handed Ryan the Knicks ticket and jogged back over to he car. He glanced at his watch and saw it was already 10:30, Beckett would probably be very grumpy by now, and he wasn't looking forward to facing her.

As he was driving home, his car announced that he had a call incoming.
From Beckett.

"Castle, are you dead or just trying to kill my patience?! If you have managed to get yourself arrested so help me-"

"No no no I'm fine, I just got held up. I promise I'll make it up to you tonight, ok?"

He could hear her grumbling, but she agreed and hung up the phone. Ryan called him a short time later and told him that he was all done. Castle had made her wait long enough, now it was time for the last part of his plan.

Castle slowly opened the door, bracing himself for a human tornado.

"Beckett, are you ready to go? I know it's 11 o'clock at night but I got us the perfect spot…"

Beckett walked out the bathroom, dressed in a soft white, flowing dress and a flower headband made of roses, she looked like the human version of mother nature and he couldn't believe he got to spend everyday with someone as beautiful as her.

"This better be totally worth it, Richard Edgar Castle, or else Ryan and Espo will be solving your homicide"

Castle winked and grabbed her hand, praying that Ryan had everything set up and ready for them and nothing had gone wrong.

Halfway through their drive Beckett realized they weren't going towards any of their usual restaurants.

"Did you take a wrong turn? This isn't the way we're suppose to go-"

"Just trust me Beckett, okay?"

He slipped his hand into hers and squeezed it, flashing her his most charming smile.

"I trust you, but please tell me we are getting there quickly. I think people in the next city over can hear my stomach growling"

"I promise"

It was midnight, and Castle finally pulled up at the park.

Beckett turned to look at Castle, not understanding what was happening

"Wait why are we at a park? Is this some kind of joke-"

"Just close your eyes and take my hands, you'll see"

Beckett took a deep breath, but did what he said anyways.

Castle led her to the small gathering by the lake, raising his eyebrows at the scene before him. Ryan really did do a great job.
There was a blanket and Beckett's favorite pillows laid on the ground, candles surrounding it, his bag laid discretely to the side and the icebox ad picnic basket lying at the end of the blanket.
"Okay, open your eyes now"

Beckett opened her eyes and gasped at the sight before her. It was like a dream, and she felt her heart swell with happiness. She could feel tears well up in her eyes, and tried to wipe them away before Castle saw them

"You– you did all this for me? How did you know I always wished for a midnight picnic? Why would you go through all the trouble?" Beckett said softly, almost too quiet for Castle to hear.

"Because the look on your face makes everything worth it."

Beckett turned around and hugged Castle as hard as she could, wondering how lucky one woman could be.

"Did I ever tell you I'm the luckiest woman in the world?"

"Only as many times as I've said that I'm the luckiest man in the world"

They walked hand in hand and sat down on the blanket, admiring the peaceful silence and cool wind of the night.
Beckett now understood why Castle had cooked so much food this afternoon, and started eating quickly while still trying to look dignified.
Castle laughed at her eagerness and poured wine for the both of them. Maybe tipsy Beckett would be less likely to murder him for what he was about to do. He could look at her forever, but there was one last thing he wanted to do before the night ended.

"You know,I'm kinda sleepy from all that wine and delicious food. Can we cuddle under the stars because it's getting cold and I wouldn't mind stealing all your warmth."

"Just one last thing, stand up."

Beckett shot him a look, but did it anyways. Castle got up behind her, and swept her off her feet before she could react.

"CASTLE! What are you-"

Beckett broke off into giggles, possibly because she was slightly tipsy.

"Shhhhh, it's more fun if you don't know"

Castle carried her over to the lake, taking a moment to double check that his bag was close to the edge and said a quick prayer that he would survive tonight.

"I just want you to know that I love you a lot and I really want to grow old with you and not die young"

"Castle-"

Even her tipsy brain knew something was off but she didn't realize that she had forgotten just one big thing.
Castle's immaturity.

Castle threw Beckett into the lake, already knowing that this could be his last day alive.
Beckett was caught off guard, but had just enough time to let out a loud yell before she hit the water. It was so cold she felt like the human version of an ice cube, and she came up gasping for air.

"RICHARD EDGAR RODGERS-"

Castle took a deep breath, then jumped into the lake. It was even colder then he had expected, he made sure to get away from Beckett before she could get her hands on him.

"I'm so sorry but I just had to do it, surely you can find it in your heart to forgive me?" Castle grinned at her like a little child, keeping a safe distance from her.

"You are so dead-"

"Well catch me if you can!"

Castle easily swam out of her reach, each time giving her a teasing smile. Finally, he stopped moving, and Beckett took her change to lunge at him. Just before she could grab him, he disappeared.

Before Beckett had time to react to this, Castle grabbed her from underwater and lifted her onto his shoulders.

"You think I would let you win that easy?"

Beckett let out a sigh of frustration and began to beat her fists against his back, not that it did anything to help her.
Castle let her drop a little, and Beckett instinctively wrapped her legs around his waist.

"See, isn't this romantic?"

Beckett mumbled under her breath, but had to admit that he had a point. She was use to the water now and it was the most fun she had in forever. It was still evil of him to throw her in a lake, but he had gone to so much trouble to make her fondest wish true: a midnight picnic

Castle pressed his lips to hers, forgetting about the cold water and the stress from writing his new novel and instead focused on how perfect everything felt. All the planning (and bribing!) had worked, and he couldn't imagine a better night or a better person to spend it with.

Once they broke apart, he placed his forehead on hers and laughed.

"What's so funny now?"

"Oh, I'm about to beat you in a race to the shore, obviously"

He quickly pushed off and began to swim away from her. Taking a moment to regain her senses, Beckett knew she couldn't win this fair. She would have to play dirty.

Castle felt a sudden weight on his back, and twisted his neck around to see Beckett on his back, grinning at him. He twisted and turned, trying to shake her off, but she had a tight grip on him and was refusing to let go.
Once they were 20 feet from shore, Beckett sprung off Castle's back and quickly swan to shore, ready to do a celebratory dance once she got back onto dry land.

"Hey, that was cheating AND dirty!"

Beckett smirked and wrapped her arms around him

"Haven't you learned that I don't lose?"

Castle grumbled but went over to get the back with their pajamas, knowing that losing in a race was the nicest way Beckett could have beat him.

"You brought my bunny pajamas!"

"They were the only ones I saw when I went into your closet, and I didn't want to spoil the surprise by taking too long"

Beckett sighed, but grabbed the pajamas anyway. It helped that being drunk made everything less embarrassing.
Once they were changed and cuddled under the covers, it was almost 5:30am and the sun was just peeking over the clouds.

"I love you Castle"

" I love you too Beckett"

They both drifted off into sleep, feeling like everything had finally settled into place for them.
