Quote #4
Open, she willed the door, open, open, OPEN! A noise like ripping cloth tore through the room. Clary heard Isabelle cry out as the door blew off its hinges entirely, crashing into the cell like a drawbridge falling. (1.6.32)
This is supernatural even in the context of this series. Clary draws an unlocking rune on Jace's cell door. No big whoop. But it is a huge whoop when she literally blows the door off its hinges, and this is a hint to her superpower she'll later discover, a power to create super-strong runes.
Quote #5
[Jace] brushed past Clary, smelling of wet leather and char. She saw him smile as he turned, and then he stepped backward into the reflection of the moon—and vanished. (2.8.222)
Using the moon as a gateway to another world is wild and crazy even for Clary, and she's seen a lot by this point.
Quote #6
"The demon energies change us, make us different—you can call it a sickness or whatever you want, but the demons who created vampires and the demons who created werewolves came from species who were at war with each other." (2.12.59)
Maia blames her hatred for Simon on supernatural forces beyond her control, instead of the supernatural racism that it is.
