When Seiji offered to take Midori out for dinner, the first thought that popped into my head was, "Does Midori eat and drink?" Because, if she does, she'd also have to...well, you know. I'm not entirely sure how that works, but I assume there's some doujinshi out there that addresses the issue. I don't think I'll be looking into it, though.
Anyway, kind of a dull episode, although valuable in that it introduces Rin and fleshes out Seiji's background some. There seemed to be a lack of humor this time around, and Rin and Seiji's bickering got old in a hurry.
