So, I was listening to my iPod on shuffle, and this song came up. I hadn't heard it for a while, and it struck me how much of a Castle/Beckett song it is. Seriously, listen to it. It's a great song.

Disclaimer: I don't own Castle. Never have, never will.

Song used: Never Gonna Be Alone by Nickelback

Enjoy :D

Never Gonna Be Alone

You're never gonna be alone, from this moment on.

If you ever feel like letting go, I won't let you fall.

When all hope is gone, I know that you can carry on.

We're gonna take the world on. I'll hold you till the hurt is gone.

Castle looked at the small, broken body in the bed. He sat in the uncomfortable, plastic shir and reached out to hold her hand. He was hesistant, though. He didn't want to hurt her.

He reached past one of the many tubes attached to her and gently took her hand. He wastched her chest rise and fall shallowly.

He wanted her to wake up He wanted her to be okay. His chest ached when his overactive imagination began running theories though his head. Theories about Beckett being permanently injured. Being crippled. Being stuck in the hospital forever. Not being able to wake up. Dying.

A tear ran down his cheek. There were so many things that were unsaid, so many things that needed to be said. There we so many things that Castle wanted. He wanted a lifetime with the detective, and he wouldn't have that lifetime if she didn't wake up.

A doctor strolled in the room, then stopped, seeing Castle. The doctor smiled softly and left the room. Castle was glad that the doctor was kind enough to give him a moment to collect himself.

He could a faint beeping sound. Ugh, he hated hospitals. They were always so dreary and sad, and cold.

Beckett's moaned and Castle's attention shot back to her. She didn't open her eyes, though, and Castle sighed.

The night slipped slowly, and Castle fell into an uncomfortable slumber. He woke several hours later, still holding his muse's hand. He blinked, then sat up quickly. She was watching him. She was awake. She was going to be okay.

"Kate." He whispered his voice hoarse.

"Hey." She smiled, then winced.

"How are you?" he squeezed her hand gently.

"Sore." She admitted.

"Well, getting by a car will do that to you." The writer agreed.

"How long have you been here? Were you here all night?" she asked, slightly concerned.

" I came as soon as Montgomery called." Castle said, thinking back. "That was about five-ish. I was getting ready to go out for dinner with Alexis. I rushed here as fast as I could. Alexis wanted to come, but I said that she should probably wait a few days. Ryan and Esposito were here, but they left. They caught a break and they got the guy. He's going away for a long time." The writer rambled.

"You slept here?" she said incredulously when he stopped to take a breath. "You could have gone home. I would have still been here when you came back.

"I wanted to be there when you woke up." He explained. "Besides, I'm your partner. I'm here till the wheels fall off. You're stuck with me. It's in the handbook." He teased.

"Hmm, I must not have read the handbook." She mused, teasing. "I guess that means I'd have to do the same for you."

"You wound me, Detective." Castle said dramatically. "You must be feeling better if you can make fun of me."

"I wouldn't go that far. It might be a while before I feel better." She admitted. "I can't be Supercop every day."

"Well, I'll be here as long as you need me." The writer told her sincerely.

"Always." Beckett replied.

"Always." Castle agreed.

And it was true.

He always had been there. He always would be. He knew it. She knew it.

Because that's what partners do.
