In the prologue, is said that only the Kingsglaive were in the Citadel during the Peace Treaty, and that the Crawnsguard and Cor where outside.

so i guess i wonder what could have possible happened if the role where reversed. So the Glaives are all outside, even Dratus, and they can't move around as they like, so they can't place the bomb on the Crystal chamber, Dratus can't infiltrate during the Party and he can't kidnap Lunafreya... staff like that, bc if the traitors go somewhere they shouldn't, someone would notice, right?

i don't have the time nor the capacity to write something like that, but if i can give someone else the idea... :D
