Faith rolled her eyes, but grinned. This guy seemed strictly squaresville, but nice enough, despite that. Still, that didn't mean she wasn't going to have some fun with him. She basically couldn't help it. Anytime she saw someone acting in any way restrained, it was like a personal challenge to try and get them to loosen up.
"I'm fine..." She said in exactly the same tone of voice he had used, and then reached over and gently punched him in the shoulder. Well, gently for her, which meant it wouldn't leave bruises. "You need to lighten up, find the fun, Ned."

Giles would just about be having kittens at the very idea that she would eat this. But it wasn't in her to not try, so she forked up a big bite and stuck it into her mouth without hesitation.
Immediately, her eyes lit up, and she gave him a thumbs up. "Guinea pig says this is fucking awesome!"
