It looks like something bad has happened to Simon, and with Raphael there, it can only mean one thing. Hopefully, whatever Clary is doing will work. And look at Jace's face. He seems genuinely concerned, but maybe it's all for show!
Valentine sure knows how to take care of his experiments. Wouldn't want his Zombie Freak to get hurt, thus the kneepads. What a good psychopath Valentine is. I hope Hodge can take this thing down!
I'm sure that Magnus has an answer to everyone's problems...including Alec's. Whatever the Clave has in store for the Lightwoods, Magnus will, no doubt, do whatever he can to help his dark-haired obsession.
Maryse Lightwood doesn't seem so badass now that Ms. Blonde from the Clave has shown up to give a piece of her mind. How do you spell trouble? C-L-A-R-Y.
