Buffy Summers & Kitty Pryde
At the comment, Buffy nodded. She could understand the concern and it might have actually been one of hers too if it wasn't for the fact that she was a slayer and high metabolisms came with the territory. Not that she would stuff her face, but she was definitely going to enjoy as much as she could until she was full.
"Hey, no worries," Buffy replied, offering a smile. "I get the whole eating too much thing. If I wasn't slayer material, it'd be a concern of mine too."
