Hi guys this is my first Castle Fanfic and I wanted to do something for the Season 5 finale and this just popped into my head. I hope you like it!

Chapter 1: Leaving Without a Goodbye

No one spoke as Lanie drove Kate to the airport. Everything was all too much to take in a few days. The job, her friends, her dad but most imporantly, her relationship if it's still there.

It played in her head over and over again. The serious expression on his face, his usual happy and cheery voice was cold and determined. The way he said he wanted more and most importantly, the proposal.

"I've been doing a lot of think about us, about our relationship, what we have. Where we're headed. I decided I want more. We both deserve more."

"I agree."

"So whatever happens, whatever you decide. Katherine Houghton Beckett, will you marry me?"

Honsetly she didn't know what to say. She was going to say that she was going to take the job but how was she going to tell him that after he proposed?

"Castle I...I got the job."

"I know. I knew you would. Kate this is your choice. This is where you stand."

"I'm sorry Rick. I'm sorry." Without another word she was gone. He slowly got up and watched the woman he love walk away from him.

The memory made her sick to stomach but that's the only feeling she has at the moment.

"Kate." Lanie says slowly, putting her hand on her best friends shoulder taking her out of her thoughts. The only thing Kate could do was give a curt nod and help get her stuff out the trunk. They both walked walked slowly with bags in head and started heading to the bagging check.

By the time both woman put the bags down and made it to check point Lanie was already in tears. Both Kate and Lanie looked at eachother and embraced as if they wouldn't see eachother again. Pulling back Kate looked back at the entrance, almost as if she was waiting for someone. Lanie noticed and sighed sadly. "He's not coming. Isn't he?" Kate voice said, cracking slightly.

"I don't think so sweetie." Before she could stop it a tear slipped down cheek. Wiping it away quickly she gave a Lanie a small smile.

"Thank you." she barely whispered before her emotions got the better of her and she started to sob. "T-thank you s-so much." Lanie pulled her bestfriend into another hug and she too started to cry.

"Flight 28 to Washington D.C. Flight 28."

Both woman pulled away and took a moment to savor eachother for the little time left."Take care Kate."

"You too." With that both woman went there seperate ways but right before Kate went in the check point she turned back looking to see that familiar face that she longed to see. She wanted him. She wanted him here. For him to walk through those doors and tell her not to go, that he loved her and wanted to be with her for the rest of his life but now she's leaving without a goodbye.

"Flight 28 to Washington D.C. is now boarding."

She turned back walking to her flight with the tear threatening to come out. She almost feels betrayed. He promised her.

He promised her Always.
