This was simultaneously the most interesting and most boring so far. We are introduced to so much random information that is somehow left out of the main plot. 
-The guards are being drugged?!?!! As part of their training TO RECIEVE PAY they receive steroid injections which then obviously bulk them up but also give them massive amounts of adrenalin that they then naturally also work off with exercise.  Resulting in all the guards being super bulky beefy men.
-We also find out a handful of the other relevant guards names finally, and their backstories.

But what's truly annoying is yet again how Aspen, now elevated a few classes in society, seems to have completely forgotten what it was like being a 6 and is fully devoted to the crown, the king, and anything he wants. He is such a rule follower that he delivers a message from the king to murder a bunch of the lower class but at least his coworker also happens to read the message and 'accidentally' put it in the burn pile. ugh
