Just something I’ve noticed:
In City of Fallen Angels, Lilith is impressed by Clary and Jace’s love. She says that it could “burn down the world or raise it up in glory.” Which is baffling in itself, considering the fact that she is the Mother of Demons and has lived since the beginning of the world or something, but she can tell that the intensity of Clace’s love is something special indeed. But what she said has also been proven to be true throughout TSC. Though their love, Clary and Jace did save the world—and their love also almost destroyed the world, too.
In City of Lost Souls, Clary goes all by herself to save Jace from Sebastian because she loves him. And Team Good wouldn’t have known of Sebastian’s plans if Clary hadn’t gone there and spread the information back to Simon through her telepathic ring. So in that case, their love saved the world.
Later on, Jace wants to give his life so that Sebastian dies along with him, but Clary refuses to let him go because she doesn’t want him to die. In Thule, this causes Jace to become corrupted because Clary is unable to stab Jace with Glorious before her own demise, so Clace’s love literally destroys the world in Thule.
And this is happening again in TWP. Thule!Jace—or Janus, as he calls himself—is so heartbroken over losing Clary that he wants to destroy the world to get her back. So Clary and Jace’s love once again threatens to burn down the world. It seems like Lilith really knew what she was talking about.
