Valentine: Oh good, you're awake. Just in time to see history being made.
Clary: You killed Jace. How could you?!
Valentine: He certainly would've stopped me if I hadn't. Of course, I love that boy, just like I love Jocelyn. See, their deaths were necessary sacrifices if I'm gonna save humanity.
Clary: Don't lie to me. You've never loved anyone but yourself.
Valentine: If that were true, then why do you think I've kept you alive?
