"'At least now I know why. I know what's wrong with me. And - maybe that's why I need you so much. Because if Valentine made me a monster, then I suppose he made you a sort of angel. And lucifer loved god, didn't he? So says Milton Anyway.'"
This quote caught my attention cause Jace says that because he has demon blood yet he doesn't really Sebastion does but he thinks he does. Clary and him are on the floor making out and thats when he says it he loves her and she loves him but he keeps thinking its him yet he doesn't know how to handle it. They are all on edge I picked this because he uses it to tell he that's why he loves her but she gets mad and wants him to love her for her not cause of the blood he carries.
