I suppose it had to happen already, considering the show ends next week. In fact it wasn't even a bad way of achieving the needed jolt for Kodaka's demented memory. Yozora's personality change the moment Kodaka uttered the nickname looked rather dubious, but perhaps it was only an illusion created by the episode ending right afterwards. It would be strange if her disagreeable personality suddenly mellowed too much. It didn't really seem all acting.

Quite a gray episode otherwise, with only a few good scenes.
