When Annie comes closer, Kaneki jerks a bit, but otherwise doesn't move. "I- don't think so. It feels pretty normal to me." he looks around for a second - no, it's not like he seems better in the dark, either.

"It changes because of those special cells -the ones that form the kagune- are activated. It's a consequence of that." a pause, s he looks back at Annie "N-not that it means the kagune will come out-" Annie has heard Kaneki's description of the kagune, but she certainly has no idea how it actually looks and Ken doesn't want to show it to her. "We can control the eyes at will."
