Kou blinks, a bit taken aback. She's... competely forgotten about the topic at hand- and somehow, he doesn't feel like it's her usual weirdness. Or, at least, not just her being absentminded. Somehow, he doesn't get the impression she doesn't know what's going on around her, or is that much of an airhead, despite what she portrays.

This... may be something to keep an eye on. It's not like he cares that much, but the sudden 'reset'- it feels wrong. It feels like Sumire.

His skin prickles- for a moment, he feels like he and Hannei are being watched, but it's gone just as quickly. A quick look around only reveals the cognitions- no sign of a real person. Hm.

... What a goddamn pain. He's way too tired for this shit.

"Nevermind," he sighs, leaning back. "I'm grateful that you returned my tape, in any case."
