So let me set this up for you guys. Clary came to Jace to show him her brand new spanking ability, and he is rightfully a little skeptical about the whole thing until she forces him to shut the hell up. Then Clary proceeds to show Jace how the runes made her drawing of the coffee cup real.
Everyone got that? Okay, I have several problems with this. I actually have been holding off talking about this until now. You mean to tell me, that it’s just now occurring to Jace and the other Shadowhunters that this could be an actual method to hide the mortal cup? You would think that for Jace especially, all the torn paintings back in Clary’s apartment would be a clue. Although, admittedly, I could slightly understand Jace not knowing about this method, because for all his boasting; Jace is still a young and inexperienced Shadowhunter.
However, I can’t quite believe that this method of hiding things didn’t occur to Hodge who has decades worth of experience as both a Shadowhunter and a Scholar. It would be reasonable to assume that Jace at some point would have told Hodge that Clary’s apartment was ransacked. It’s is also reasonable to assume that Jace would have mentioned the state of the paintings.
You would think that Hodge with his supposedly ‘high intelligence’ would have put two and two together and realized that it was a huge possibility that Jocelyn hides the cup in one of her paintings. Yet, we are only hearing about this now? It’s only fair to come to the conclusion that once again Cassandra Clare didn’t think this plot twist through and now it’s coming back to bite her in her ass. Because this? This is a plot hole and a really obvious one at that.
Another issue I have with this is passage is that Jace is just now questioning how Clary has instant knowledge of the runes. Runes, I would like to remind you that she logically shouldn’t have known in the first place. I also have to ask why again: Why did Joceyeln teach Clary the runes, and then proceeded to have Clary’s memories erased? Magnus said very plainly back in Chapter 13, that there was no true guarantee that Clary would ever receive all of her memories back.
Clary looked at him sharply. “Will I get all my memories back then? Whatever was taken out of my head?”
“I don’t know. They might come back all at once, or in stages. Or you might never remember what you’ve forgotten over the years. What your mother asked me to do was unique, in my experience. I’ve no idea what will happen.”
At this point, the only way Clare could make this plot point make sense if she pulls something out of her ass later that clears up this mess in a logical thoughtful way. And as Clare has shown us throughout the entirety of this book, she has a really hard time of doing that.
