Warning: Full spoilers for the episode below. While I'm certainly more than ready for Ruby to catch up with Ash (seriously, let's get this done), "The Host" nicely tied up the Elegos story that began a few episodes back in "Books from Beyond." No, Elegos didn't have any master plan other than just wanting to mess with, and kill, our heroes - and we haven't really seen many Deadites since his arc began - but it still was supremely satisfying to watch Ash blast that demon's head apart.
