@TheMinorFall. Fair enough. I can figure it out, but I don't know enough about the queen or blankface or aori to be comfortable extrapolating their actions, as they are not mine. ^.^;;
I'm going to guess that blankface was in aogiri but not quite as...indiscriminately violent, in general, and a tempering influence. So okay, that'd make Cera willing to help, as I said. I don't really know queen's goals, so I am not certain what the city might have, or what might have bothered them about the way it's run...hm, perhaps tey disagree with "monsters" staying out of eight, and feel they shoyld openly acknowledge their abilities? So they're causing trouble, and particularly in towns where most of the folks get alonquietly, so there's a reason more of them get exposed, and so they're more of a concern to the humans?
