Something in her chest went warm and tight at that smile in a way she hadn't been prepared for and didn't entirely understand. It was... Perhaps she was being presumptuous, they really hadn't known each other all that long, but she just suddenly knew with a solid certainty that he didn't smile like that very often. She'd seen his polite, neutral mask, of course, and she'd seen real but subtle emotion from him slip through it, but that...it was something else.
"I-I'm glad too," she managed to stammer out, feeling suddenly flustered and distinctly lacking eloquence. She managed to shake it off a bit as his expression sobered, and she sat forward to listen when he spoke in a different tone. The sort of tone that said he was broaching a serious subject.
She frowned a bit as he warned her against speaking about her gift--not because she didn't want to take his advice to heart, but more... "I--I will keep it in mind, Keiran," she assured him, "but I just can't imagine--I mean, surely I can't be of that much interest to the sort of folks your family will be hosting?" She laughed a little, sounding caught between incredulity and self-consciousness. "The most I can do is summon up a pretty bauble or two. I know it's...unique, the way I do it, but it's not all that powerful."
Perhaps the most ridiculous part was that she genuinely believed what she was saying: that she was unextraordinary, despite what he had already seen of her gifts. She just simply couldn't understand how someone might find her "valuable".
But she smiled at him and added, "But I won't talk about it with your family's guests, if you think that's best. I promise."
