ok but aren't shadowhunters supposed to be the protectors?? why are they always running away and letting downworlds deal with the threat for them?? their job is to protect downworlders and mundanes!! so they should do that!! jace and clary shouldn't have gone throught the portal without dot. if anyone was supposed to stay and fight sebastian that was jace, bc he didn't have the mirror, which they need to protect, and he was a shadowhunter. like?? why don't they ever do their jobs??
