Krok wasn't really expecting to hear an answer. Certainly not that question. He blinks and looks around himself first; that was Kagerou's voice, he's sure of it. As sure as he can be, given how piecemeal his memories of the last few months still are. He's sure that's Kagerou, but he doesn't see the sad fellow anywhere.

Then he remembers with a wince that Kagerou has wings. So he looks up.

"Why what?" he prompts in a deliberately calm tone, trying not to take out his frustration on Kagerou. He remembers how little the other bot always seems to think of himself and he'd hate to add to it. "Why must I be going insane?" He gestures, not quite a shrug, hands open and upturned. "I don't know. I think I just am."
