In this midseason episode, the story heavily implies that the peace resulting from events that happened before the series started, ultimately come from a great cost on everyone involved. The setting has its own skeletons to hide, but everyone seems to have accepted it and are trying to move on with their lives. There are quite a number of humorous moments this time and a very emotional climax to boot. But I guess this is where everything changes from now on, can't wait to see how that goes.
