Valentine Morgenstern: Look, I know that you have always felt more powerful than everyone else around you. That’s because you are.

Valentine Morgenstern: I made you stronger, faster… More lethal than any other Shadowhunter.

Jace Wayland: Why?

Valentine Morgenstern: To create the perfect weapon, the ideal marriage of good and evil. A Shadowhunter with pure demon blood.
