With Hodge's permission, Clary and Jace return to Clary's apartment to search it for clues about her mom's whereabouts.
The apartment is empty. Everything is gone—the furniture, their decorations, her mother's paintings—as though they had just moved out or something.
Just as they're about to search Clary's room, they get ambushed by a giant troll-like creature.
Jace kills it after a fight that leaves Clary winded and Jace's arm broken.
It just takes a quick scribble of a healing rune on Jace's arm with his stele to fix the broken bone. Hey, where can Shmoop get one of those?
Clary finds out that the creature wasn't a demon; it was a Forsaken. That's an ordinary human who has had one too many runes carved into him, making him deformed and crazy. So remember that, Shmoopers, when you're on your fourth barbed wire tattoo.
After he's explained everything to Clary, Jace decides to head back upstairs to see if there are more foes afoot.
But he's stopped by Madame Dorothea, Clary's psychic neighbor. She eerily knows a lot more than we expected her to, like about the Clave, the Covenant, and the Forsaken. Looks like she's not just some hack psychic after all.
Clary learns two things from Madame Dorothea: Jace's last name (the totally non-heroic sounding Wayland) and that her mother might still be alive.
