Alternate ending to the first episode: if Kate had taken Rick up on his offer to be one of her conquests.
"How would you like to go to dinner?" asked Castle, I took the twinkle in his eye and the mischievous smile on his face to mean thats not all he wanted.
"Why, Castle, so I can be another one of your conquests?" I ask.
"Or so I can be one of yours."
"It was nice to meet you, Castle," I say, smiling.
"Thats too bad, it would have been great," he said.
"You have no idea," I leaned in a whispered in his ear, I could sense that he tensed up when my breath hit his ear. He grabbed my hand and started walking towards his town car.
"If you want to tease me like that, you at least have to accompany me to dinner," he winks at me as he opens the door, I surrender and step inside.
It's quite sexual so if you don't want to get turned on, don't read it.
