As it was, it was too powerful for her to hold back, and her eyes ended up widening the more he spoke, and she just looked like she'd been slapped in the face. She didn't want to make him feel awkward about it, but she couldn't help it. Was he actually suggesting that they spend time together like that? Time that didn't include killing things or cleaning wounds?
Slowly, she gave him a smile that didn't stop there. It only took seconds until it turned into a small grin. "No, no, that's... I'd like that. We can definitely do that. Just hang around and be bums, there's really no better way to celebrate."
