As far as the humans are concerned, I don't want to see Satouru die, that's about it. I really do dislike the arrogance of a lot of the humans. It seems like our main characters are the only ones with any empathy with the queerats even if they're pretty bad themselves. I'm kiiiiiiiiiiiind of rooting for the rats. Besides, Yakomaru is just too damned entertaining not to be rooting for him. It'd be like watching the Dark Knight and not rooting for the joker. Hogwash!
And um...Kimomaru is totally in on all this. That smirk he displayed last week totally gave him away. I suspect both he and Yakomaru leveraged the favors done for group 1 in the past to enlist Mamoru and Maria, combine with some brain washing by way of sympathizing with their plight. Furthermore...I'm entirely convinced that the skeletons Saki and Satoru returned to the village were human skeletons. I think Yakomaru, by that time, had already seen or taken part of the murder of a cantus user. The remains are probably from said user. This was already a great episode, I can't wait to see what comes next. Crafty rats...
