Description
I got this idea from the "The Shadowhunter's Codex" from Clary thoughts.
It was on page 35, under the title 'My sensor has vibrated so much that it had ignited and exploded."
Clary: "So if you had a human who'd drunk a lot of Greater Demon blood when he was a baby, would he set off a sensor?"
Jace: "Who would do such a terrible thing?"
Clary: "Just hypothetically."
I'm going to assume this is a supernatural reference...
Jace Wayland- Cassandra Clare
Sam Winchester- Eric kripke
