Well, it sure is shaping up to be a solid YA offering. Where's part 3 Inna? Where?! :P

Now, no answers given, ok, a couple, but many more questions. Who do they patrol against? What does it mean to be part of The Citadel? Only kids?

I really left that offhand remark on "uncool," which clues us into two things - first, they are the ones watching over one another first and foremost. Who better to guard and point out dissidents than those who are afraid to be accused of it themselves? Second, Eton is still very much a teenage boy, who cares about being seen as "uncool", even if the meaning is different here - unfeeling, and thus safe.
