His serious response made her chuckle. Instead of being put off by it, she was amused. Faith had never met anyone as naive and unused to human customs like Castiel before, and she knew that their conversations from here on out would only serve to amuse her. Shaking her head at him, she laughed again in response. "Thanks for the info, Captain," she replied with a snort. "Although I did mention I require a meal or something before the clothes start falling off. I'm easy, sure, but not that easy."
Then again, she might be stretching the truth there. It had been ages since she had sex, and she was a deeply sexual being. The last time she had gotten laid was long before her incarceration. That, coupled with the fact that she was eight years in the future was depressing. She had to wonder if she gained her virginity back from the lack of sexual contact. "You're wicked funny, Cas," she said suddenly, smiling at him. It lacked the usual coyness or dryness to it. Instead, it was just a genuine smile. "Didn't think someone as uptight as you would be this entertaining."
