im-Prompt-tu Chapter 7: I Cannot get You Out, a castle fanfic

This prompt is from borninthecastle445: Castle finds Beckett playing her guitar and asks her to sing something to him, it could either be a song that they both know or her own song about him or something. Set late season 3, NO JOSH.

After a two week long case with barely any leads, Castle's theories, and multiple espressos dished out every hour, everyone wanted to go home and relax. Ryan would go home to Jenny and catch up on some much needed one-on-one time. Espo would go to Lanie's apartment, even though he wouldn't admit it, everyone knew. Castle would go home and see his daughter, the whole time they were working the case, Alexis repeated herself every time he asked to leave with, It's fine, or, Go dad, they need you there, but he knew she missed him. As for Beckett, the team figured she would go home and sink down into a bath with a book and a glass of wine like she usually did. Only she knew the truth. She would go home and pick up the acoustic guitar her mother gave her five years before she died. On the neck of the instrument were the words, To Jo. Vincit Omnia Veritas. She would dance around her apartment and belt out classics as she strummed away. She would set the guitar in front of her and pluck at the strings as if it were a base, sometimes breaking them, but in her mind it was all worth it.

Castle had gone about an hour prior to when Montgomery kicked her out of the precinct, and the boys left soon after.

Alexis hadn't known that the case would wrap that day, so she was at Paige's house for the night. Rick's mind had been buzzing ever since the case started, he had tons of inspiration adding up as the case went on, but he wanted to stay and help. He had the night to himself to write.

Across town, Kate's apartment was the exact opposite setting of Castle's. She had music playing and she was dancing around singing and playing her guitar. After twenty minutes of strenuous dancing and lung bruising singing, a slower song made its way through the radio. She walked over to the radio and turned down Christina Perri's A Thousand Years, and started playing and singing it as she knew it by heart.

"Heart beats fast,
Colors and promises.
How to be brave,
How can I love when I'm afraid to fall.
But watching you stand alone.
All of my doubt,
Suddenly goes away somehow.

"One step closer.

"I have died every day,
Waiting for you.
Darling, don't be afraid.
I have loved you,
For a thousand years,
I'll love you for a thousand more."

She softly sang the song as she played the few guitar chords that go along with the song.

"Time stands still.
Beauty in all she is.
I will be brave,
I will not let anything take away,
What's standing in front of me.
Every breath,
Every hour has come to this.

"One step closer.

"I have died every day,
Waiting for you.
Darling, don't be afraid.
I have loved you,
For a thousand years,
I'll love you for a thousand more.

"And all along I believed I would find you.
Time has brought your heart to me.
I have loved you,
For a thousand years.
I'll love you for a thousand more.

"One step closer.
One step closer."

Castle was having trouble with one of his plot-twists, so he called Beckett. When she didn't pick up the first time, he called again, and again, and again. He began to think that something was wrong, so he ran out of his office, phone in hand and grabbing his coat in passing. It took two minutes for him to hail a cab, which was good for the time of night it was. There was light traffic, so it took just over five minutes to get there.

While he sat in the back, he couldn't help but think what his life would be like without her. How terrible it would be, how dull. Lost in his thoughts, he didn't notice that they had arrived until the cabbie yelled at him to pay-up and get out. He threw a stack of cash at him, probably fifty dollars which was too much, but he didn't care, and fled to the door of her building.

The doorman merely acknowledged him as he ran to the elevator. Rick hit the button to go up multiple times, but it was several floors above him. He slid over to the stairwell and took them two at a time until he reached her floor.

Bursting through the door to the main floor, he slowed his pace and walked to her door. A soft sound rolled around the inside and seeped under the door, flooding his ears with what he'd always imagined an angle's voice sounded like.

"I have died every day,
Waiting for you.
Darling, don't be afraid.
I have loved you,
For a thousand years,
I'll love you for a thousand more.

"And all along I believed I would find you.
Time has brought your heart to me.
I have loved you,
For a thousand years.
I'll love you for a thousand more."

He could tell the song finished when he heard a guitar being strummed one last time. He didn't want to interrupt her peace, but he had to ask her about what he should do in his book, or else Gina would torment him until he got it done.

The next thing he knew, the knuckles on his left hand made contact with her metal door. There was a fast shuffling sound, and then the door seemingly pulled itself open, proven wrong when her head poked off from the side and peered at him.

"Hey."

"Hey, Kate." he said wearily.

"What's up?"

"Uhm. I... I don't know?"

"You don't know why you came over here?" she laughed.

"No."

"Well okay then, come on in."

"Thanks."

"Yeah."

She stepped back, making more space between the door jam and herself, and he meandered in. She hadn't expected whoever was at the door to come in, so she didn't bother to hide her guitar. "Want something to drink?" she offered, slowly backing into the kitchen.

"Ah, sure." She walked to the cupboard where she kept wine glasses and poured some Cabernet Sauvignon into each. When she went back into the living room, she saw Castle staring at the guitar. "You have a beautiful voice." he stated nonchalantly. He face turned white, only to heat up and turn a deep red.

"I didn't think you heard me."

"Oh yeah, I was standing out there for, maybe the last third of the song? Yeah, that's about right. Nice instrumental skills too." he smiled. "Can you play something for me?"

"Um. Well I suppose... Since you already heard me, sure." she smiled weakly at him. "I just don't want to play the guitar for this, I want you to really listen to the lyrics. Okay?"

"'Kay."

She started,

"Nothing goes as planned.
Everything will break.
People say goodbye,
In their own special way.
All that you rely on,
And all that you can fake.
Will leave you in the morning,
But find you in the day."

She glanced up to see him staring at her, with what she would call, "Love" brewing in his eyes, threatening to boil over. She took a deep breath and began again, but didn't notice until the second line that Castle was singing with her.

"Oh, you're in my veins,
And I cannot get you out.
Oh, you're all I taste,
At night inside of my mouth.
Oh, you run away,
'Cause I am not what you found.
Oh, you're in my veins,
And I cannot get you out."

He was singing about an octave lower than her. As they sang, the sound waves bounced off the walls and came together in a perfect harmony.

"Everything will change.
Nothing stays the same.
Nobody here's perfect.
Oh, but everyone's to blame.
Oh, all that you rely on,
And all that you can save.
Will leave you in the morning,
And find you in the day.

"Everything is dark.
It's more than you can take.
But you catch a glimpse of sun light.
Shining, shining down on your face.
Your face.
Oh your face.

They inched closer, and interlaced their fingers, staring each other in the eyes. Hazel boring into blue, and vise versa, so much said, yet no mouths opened.

"No, I cannot get you out.
No, I cannot get you out.
Oh no, I cannot get you."

They smiled at each other, once again, and moved closer even more. Their eyes slipped closed, and neither of them knew who closed the distance, before their lips touched, it didn't matter at that moment. The kiss was slow and soft, yet explosive and hungry. Only they could make it work.

A/N: Guys, I NEED prompts, this was the last one that I had to do, and I'm desperate.

Thanks,

Sarah :)
