Zagreus does not like being visually assayed. In fact, he liked her honest distress considerably more than her self-possession. Self-possession is usually considered more a bug than a feature, in AIs. She's not really apologising for the right inconsistency. Which, he's definitely known humans that were more even-keeled than this AI, or did a better job of pretending to be, anyway. "Has it been your experience that time fixes things?" he says, in a tone of polite if disbelieving interest. Is it really of no concern to her whatsoever that a real actual being is in her dream? Well, maybe as someone who doesn't dream, she's unaware that that is highly unusual. It's not like it's something he orchestrated anyway. "Then maybe that will still be the case." He doesn't sound hopeful, but it's well-meaning enough. "What sort of artificial intelligence? Beyond unsleeping and non-sneezing."
