This idea sort of just hit me out of the blue. It's based on something Nolan Ross said to Padma Lahari in episode 2x17 of Revenge. You should still be able to understand it if you haven't watched Revenge (I highly recommend watching it, though). This is pretty short, but I hope you like it.

Nolan: Hey, this isn't the way that things end for us. Someday you'll be sitting on a beach somewhere and you'll find out that the Initiative was exposed and the threat is gone.

Padma: You better be walking down that beach ten seconds later.

Nolan: I will be running.

"Jo Houghton Rodgers...fitting." He couldn't help but laugh, a hollow sound that bounced around the empty room. The new i.d. was clutched in his grasp, the passport rough against his palm.

"Castle, I don't think I can do this." She gasped out, not even bothering to swipe away the tears falling down her face. "I can't live with out you. I just can't."

"Oh Kate," He sighed, closing his eyes against the tears threatening to fall, "No, hey, this isn't how our story is going to end. Someday you'll be sitting on a beach or walking by the Eiffel Tower and you'll find out that LokSat was caught, and that the threat is gone." He did the only thing he could think of, he kissed her, soft and sweet.

"You better be walking down that beach ten seconds later." She said, leaning her forehead against him and managing a heartbroken smile.

Castle scoffed, "I'll be running."

"God, Castle. I love you." She smashed her lips to his, sucking his bottom lip into her mouth as her left hand found purchase over his heart. The other arm wrapped around his neck, her nails scraping against the hair at the nape of his neck. She ran her tongue over the seam of his lips, memorizing his taste, his smell.

He wrapped his arms around her waist, pulling her close; aligning their bodies so there was absolutely no space between them.

"I love you too, Kate." He replied, not even realizing he was crying until he felt her hands rise to his face, thumbs brushing away the tears the second they fell.

He wrapped her up in a hug, molding her body to his once again as he took in the soft scent of cherry and vanilla that was uniquely her.

"I'm sorry. I'm so sorry, Castle." She sobbed into the crook of his neck.

"Shh, honey, none of this is your fault." Rick said, pulling away only enough to look into her eyes.

"I pushed too hard, and I couldn't just give this up." She stopped at the shaking of his head.

"No. No, Kate, you didn't start any of this. Please, stop blaming yourself. Promise me you'll do that for me, okay? Our story is far from over, and someday soon we are going to have our happily ever after."

"Thank you." At his confused look she continued, "For loving me. For taking me back despite the hell I put us through. Thank you for making me believe in magic again."

"Always."

Phew. Okay, I have a second part to this that I will hopefully have up tomorrow. It will take place in the future once Loksat is gone. Sorry for the angst, the next chapter should be better. Thoughts?
