So in the last chapter and also in chapter one, Jace has outright confirmed that demons exist and that its his and his friend’s job is to kill demons. Now, any logical person face with that truth, and with the all the angel themed crap decorating the Institute would automatically assume that the Shadowhunters are angels themselves or affiliated with angels. Does Clary ever come to this conclusion? Nope! It just goes way over Clary’s head. Clary never asks Jace about the angels, never even questions it in her own thoughts. Clary just continues her tour with Jace as stupidly oblivious as she always is.
