Valentine: You're my daughter. Clary: Why would that stop you? Jace is your son. You've hurt him plenty. [Valentine evil smiles] Valentine: You didn't tell her. Clary: Tell me what? Valentine: You must still have feelings for her, huh? Now isn't that a pickle. Jace: Not another word. Clary: What is he talking about? Valentine: You want to do the honors or shall I? Jace: Shut up! [Jace punches Valentine] Valentine: It's rude to keep a girl waiting, Jace. Clary: Jace, what is going on?! Jace: Valentine is not my father...I'm not your brother, Clary.
Jace: You experimented on me? Valentine: I made you stronger, faster; more lethal than any other Shadowhunter. Jace: Why? Valentine: To create the perfect weapon, the ideal marriage of good and evil: A Shadowhunter with pure demon blood.
