I have to agree with Oreki, I don't really understand what Fukube was talking about. Especially since not so long ago he was very seriously trying to beat Oreki in detective work. That isn't overly consistent with what he was saying here. Although I suppose being inconsistent is human. Still, he was a real douche by ruining Mayaka's effots. He sounds almost as stupid as people who believe they don't have the right to be happy for whatever reason.

Aside from that depressing stuff, I wonder if Chitanda confessed to Mayaka that she likes Oreki. Being the airhead she is, she didn't give him any chocolate because of family traditions that, I'd think, don't really apply to situations like this at all.
