A/N: This is set after Law & Murder. I wanted to have this done like last week (no, but right after I watched it) but it took me until now. It so was a date they had! Thank you guys for reading and reviews are very much appreciated. Flashbacks are written in Italics. If you want me to, I thought of posting a second chapter with the next morning. Up to you. Huge thanks to my awesome beta eLynda again! You are amazing! Thanks for your time!

It's A Date

Castle still couldn't believe it. There he stood with Kate Beckett holding hands on her doorstep. How it had come to this was very easy to explain. They had been out on a date. Of course, when the evening had started Kate had denied it was one but Castle knew better. They had been out to see Forbidden Planet and then to Remy's. Castle remembered every single second of the evening, starting with the invitation.

"My treat." Kate smiled widely.

As they walked over to the elevator Castle started to push his luck.

"Maybe we could stop at Remy's?"

"Now you're pushing it."

"Oh, well."

"Just kidding."

And he was successful at last.

It had been a while since he had seen Kate so happy and herself. It was refreshing to see her fangirl side and he couldn't help but smile. When the elevator doors closed he grinned at her.

"What?"

Castle's smile only grew wider and Kate got a good idea about his current thoughts. She knew him well enough.

"It's not a date, Castle."

"I'm sure everyone would agree with you." He answered in a mocking tone.

She glared at him but the smile on her face told him a different story.

Then they had gone to see Forbidden Planet.

After maybe half of it he understood why Kate loved it so much. There was a sparkle in her eyes every time Castle glanced over to her, a content smile on her lips. He had loved the film before, but watching it next to her made it even better.

When he was sure he wouldn't get killed by her, he gathered up the courage to lay his arm around her shoulder. Kate looked over at him frowning but he was still watching the movie so she took the time to study his face. Moments later she smiled to herself and her attention went back to the film. When Castle realized she wasn't going to kill him at all, he smiled as well.

This was so a date.

When the movie finished they smiled at each other softly.

"Remy's?" Castle asked not wanting to break the moment.

"Definitely! I'm starving," Kate answered, her smile widening.

She grabbed his hand without thinking twice about it and ran off to her car, dragging him behind, laughing.

At Remy's they both had a burger and some fries.

Kate had her own fries finished in no time so she started stealing some from his plate.

"Hey!" He tried to sound offended but failed miserably.

She was just too cute.

To her own surprise Kate almost started to giggle about the two of them so she stuffed another fry in her mouth to stop herself. She couldn't help the blush, though, and as much as she hoped Castle wouldn't notice, he did. He grinned widely but didn't say anything. They sat there in silence until he asked if she wanted to go home. Kate nodded and they left for her apartment.

That's how Castle had ended up at Kate's doorstep holding her hand. He smirked at her again.

"What this time, Castle?"

"This was so a date."

"Nope." Kate smiled back at him but her tone was serious.

Castle tried to look hurt and disappointed but something in Kate's smile told him that there was more.

She bit her lip shyly and then got on her toes to gently brush her lips against his. Then again. And again.

"Now it was a date." She whispered against his lips, her eyes still closed.

She could practically feel his smile when he kissed her again.

"I should go now." Castle said bringing some distance between them.

Kate bit her lip again. She could hear that he didn't want to leave now and she didn't want him to go either but she nodded eventually.

"I'll see you tomorrow?"

"Of course. I had a great time tonight, Kate. Good night." Castle smiled at her and she nodded again.

"Me too. Good night."

He left when she went inside. A minute later she received a text message from Castle.

Forbidden planet is definitely my new fav. Night, Kate.

Kate smiled at her phone. She was glad that she had broken up with Josh earlier that day.
