Sebastian Morgenstern: You always cared more about the Mortal Instruments than you did your own son.
Valentine Morgenstern: That's not true. Despite everything I've done, I have always... always cared about you.
Sebastian Morgenstern: Do not lie to me. If you truly, truly cared about me, you would have never sent me away.
Valentine Morgenstern: I made a mistake. It was Jace that was...
Sebastian Morgenstern: Shut up!
Valentine Morgenstern: The sword still compels the truth. Jonathan... not a day goes by that I don't think about you. Where I am not haunted by that decision I made. To send you to Edom.
Jace Wayland: You didn’t inject me with demon blood. It was angel blood.
Valentine Morgenstern: You are my greatest achievement, Jace.
Jace Wayland: I’m not your achievement. I’m your son.
Valentine Morgenstern: No, you are not my son. I’m not your father. Jocelyn is not your mother. And Clary… Clary is not your sister.
Valentine Morgenstern (to Clary): I am doing this for you, and for your brother, and for the rest of humanity. Clarissa, this planet is under siege by demon-blooded creatures, intent on death and destruction. Once I wield that sword, the Downworld will no longer be part of our world. And the lives of my children… will be that much safer.
