-Maybe spoilers-
Why is Eto showing up? Was this shown in the Manga? I don't remember.
-Relevant to Anime-
Well, hopefully Hide will see Kaneki as a ghoul, since its apparent that he is in the 4th division. The owl fight was mediocre, seeing as it was still scenes of him standing still, taking blows, and then returning a few ones with choppy animation. Wasn't that impressed since Studio Perriot has way more budget for something higher than that.
-Will Kaneki die?
-Will Hide see him?
