Julia tells Quentin what she remembers (i.e. what Ember unblocked from her mind): turns out instead of conjuring Our Lady Underground, they actually conjured Reynard The Fox, a trickster who possessed Richard, killed the other people in Julia's Free Traders group; and was about to kill Kady before Julia stepped in. Then, in a gruesome scene, Julia was raped and left for dead. She then called Marina, who helped her dispose of the bodies and erase her memories. After telling Q all this, Julia makes him swear to help her find and kill Reynard. That was awful, team. Just awful.
