Last episode sucked. Oreki has changed because he's actually doing something bothersome of his own free will. And the reason he did it was for Chitanda. And at the end they implied he has feelings for her. People were hoping for all these things and they actually happened, so it should why did I say it sucked? Because it was all so predictable and boring. Chitanda is pretty and Oreki gets embarrassed looking at her - it's already happened in every episode. There was nothing new in this episode. And they just crammed a mini-mystery in there because this show is supposed to be about mysteries, but it was just bad. It was obvious and stupid. I didn't especially dislike this episode or anything, but it's just disappointing because it could have been so much better.
Oh, and it was definitely the last episode. There won't be any more, unless they make an ova or something.
