Well at least that explains how Kotomi was able to talk with Tomoya easily, thinking back to when Tomoya asked her about it. Hope they give a good reason for why he forgot about her and wonder if the whole hidden world is related to the dream Tomoya has about the girl and all that. Well hoping that Kotomi won't leave the show after her arc, more fun to see her hang around and the "bad guy" is kinda weird the things he talked about and everything made him seem yeah just plain weird
