Lyssa slumped a bit- she knew he was making good points, and she hadn't really expected him to stay, but she had hoped, a little.
A frown stole over her face and she opened her mouth to correct herself, to say it wasn't because she felt that she owed him necessarily but because she wanted to do something nice, something to say thank you for how kind he'd been to her.
Whatever words she'd been trying to say died in a choked squeak and her eyes went wide. "O-oh, um, I d-didn't think about that," she stuttered out, cheeks positively emerald with her blush. "I- I suppose it is getting late, I've lost track of time, I didn't mean to impose or- or put you in an awkward situation..."
Great, now she couldn't even look at him, eyes fixed on her feet as she stammered out apologies.
