Yo! This is my first Castle fan fiction and I'm super duper excited! I honestly can't take it anymore, when is it September. Ever I since I saw the new promo that came out this week, I've been freaking out! So...to calm down my freak attack, I decided to write what I think will happen. So, Hope you enjoy! :)

WARNING: THIS CONTAINS SPOILERS FROM THE NEW PROMO. IF YOU DON'T WANT TO KNOW ANYTHING THAT HAPPENED IN THE PROMO, LEAVE THIS PAGE NOW!

Disclaimer: If I owned Castle, I would be writing a real script at the studio, not on a fan fiction website.

"Will you marry me?" Castle asked on one knee.

"Oh my god, you're proposing!" Beckett jumped with wide shocked eyes. Castle looked at her with confusion and nervousness.

"I...I..." Beckett stuttered, not knowing what to say. She grabbed his hands. "Listen, there's something I have to tell you." She said calmly. Castle looked at her in her eyes. She took a deep breath and said,

"I took the job in DC." Castle face turned into a frown. "I understand. I said whatever you de-" he started.

"I wasn't finished." She interrupted. "That doesn't mean I'm saying no." She smiled. Castle smiled back and grabbed her hand and place the ring on her finger. They both leaned in until their lips were touching.

"I promise you to visit you in DC." Castle said when they pulled away. "You better." She joked. "But I'm sorry for leaving for this job." She continued, feeling bad. "Hey, no worries. This job is perfect for you. I'm proud of you. Once you get fully trained, you try to get a job here." Castle explained smiling.

"Thanks Rick." Beckett responded, smiling back. Castle smiled even wider when she called him by his first name. "Always, Kate." He said grabbing her hands.
