Lyn wondered if father 'approved' of Kazuya and her dating. She never asked about his stance on the issue, because she felt it wasn't necessary to ask. It didn't make a difference whether anybody approved of her relationship with Kazuya at all. Nothing would change, she would still date him. However, the more Lyn thought about her father's behavior towards Kazuya, the more that thought resurfaces.
"Lyn? What's wrong?"
"Ah, nothing," Lyn looked around, "Kazuya, I'll heal your injuries."
"Mmm, okay. There are no recorders here or anything to detect magic. So they shouldn't notice. Make it light, though; it would be strange if I recover completely."
