Just a short one shot based on the promo for "Always" slight spoilers:D

I don't own anything

"I'm more then a partner!" he said grabbing her arm and turning her back to face him.

"Yes you're the thorn in my side!" she snarled "Let me go."

"I'm your friend Kate." He said ignoring her comment.

"so let me go so I can get this bastard."

"I cant…" he said although his grip loosened

"Why not Castle. I could have him. Do you want me to loose him again?"

"Of course not but…" he grabbed her other arm and tried to bring her closer to him, she retaliated by shaking him off and slapping him across the face. He recoiled with the sting flaring across his cheek his hand shot up to cup it.

"I said let me go." The rage was burning in her eyes and she just turned and walked away from him.

"I love you Kate! If that means anything just don't do this." she stopped but didn't look at him. "You know that I love you and I will do whatever it takes to keep you safe."

"Stop it Castle." She whispered. He walked up behind her

"if what we have means the slightest bit to you, you will stop this and save your life." He said softly into her ear. She flinched as his hot breath went down the collar of her shirt, the light white fabric puffing slightly round her shoulder.

"What do we have…" she said in a voice that was barely audible.

"Everything. We could have everything if you just stay here." his hands took her shoulders and he began rubbing his arms up and down her arms, but again she pulled away and walked towards the door. "You can't run away from me forever Kate." He said watching her walk away.

"I can't be with you until he's locked up." She said stopping again at the door.

"If you go after him I'm gone. I…" his voice broke. "…I can't wait any more." She turned around slowly.

"I love you." She smiled, tears in her eyes. "But he's had my life on hold for fifteen years. You know I can't stop."

"I won't wait." He said trying with all his might to sound like he meant it.

"I'll always come back to you." She said the smile falling. "Always."
