My first impression of the episode? "Koizumi, is that you?" Damn, those closed eyes makes that senpai a spitting image of him.
Overall, kinda unimpressive episode. I particularly liked the story book part, which was well done, but the rest was like "okay lets just get on with it already" feeling for me. Except for whenever Ibara interacts with Oreki, which as a shipper I can't help feel giddy about (even though Chitanda does the same thing, can't be a shipper unless you can hold double standards about other ships lol)
Seriously speaking though, maybe it's because I feel miffed that the location of the back issues was revealed rather anti-climactically, with all the build up from the previous episode and all. Sure there's the new mystery as to where's #1, but I dunno, I don't want to set myself up for disappointment for the chance that Aneki is going to reveal where the location for that one is as well. :shrug:
