Jace Herondale: You taught me not to feel. You taught me that "to love is to destroy, and to be loved is to be the one destroyed."
Valentine Morgenstern: And you've proven how right I've been all along. Look at you. Your love for Clary, it will be your downfall.
Jace Herondale: I was surprised. Kaelie didn't seem capable of such brutality.
Seelie Queen: Precisely why she made an effective killer. The sweeter the honey, the deadlier the trap.
Jace Herondale: That is called a kill tree. It would have wrapped its vines around you and torn you limb from limb.
Clary Fray: Jace, what the hell are you talking about?
Jace Herondale: That tree almost tore Simon's pretty face off.
Simon Lewis: You think I'm pretty?
Clary Fray: How did you know Kaelie?
Jace Herondale: Book Club.
Clary Fray: You read?
Jace Herondale: Yeah. Why does everyone find that so hard to believe?
Sebastian Verlac: Where did you learn? Who taught you?
Jace Herondale: Valentine, if you can believe that.
Sebastian Verlac: Huh. I guess even an evil mastermind can appreciate fine music.
Jace Herondale: Yeah... maybe a little too much. Whenever I would make a mistake, he'd break the offending finger, then Iratze my hand and have me start again.
Sebastian Verlac: Well, I, uh... I'm surprised you still play.
Jace Herondale: Only when the mood strikes.
Jace Herondale: You're taking over. You, Alec Lightwood, are now the Head of the New York Institute.
Alec Lightwood: Can you do that?
Jace Herondale: Yeah. I mean, like you said, being a Herondale comes with certain perks. Naming a successor is one of them. You were right. Downworlders and Shadowhunters, we're all a mix of human, angel and demon. If we let the Clave forget that... we deserve a revolt. I'll always be a soldier. But you're a leader, Alec.
Luke Garroway: You want a Downworld revolt? This is how it starts.
Jace Herondale: They came after Clary.
Luke Garroway: What?
Jace Herondale: Look, she's Okay, Luke, but...
Luke Garroway: It's not about Clary. And it's not about those dead Shadowhunters. It's about starting a war. Do you want that blood on your hands?
Jace Herondale: It should've been you. I told her that.
Alec Lightwood: The Clave was never going to hand it to me. I'm dating a guy who's a Downworlder.
Jace Herondale: Look Alec, I didn't want this, I swear.
Alec Lightwood: You're a Herondale. Get used to the perks.
Clary Fray: How did you do it? You activated a rune without your stele.
Jace Wayland: I don't know. Saw you lying there. And it just kind of... ignited. On its own.
Clary Fray: None of this makes sense. But we'll figure it out. The two of us.
Alec Lightwood: Clary’s not your sister?
Jace Wayland: No, she never was.
Alec Lightwood: What are you gonna do?
Jace Wayland: I’m gonna tell her.
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.
Alec Lightwood (to Clary): You did this. You activated the sword?
Clary Fray: No.
Jace Wayland: I did it. I thought I was destroying it, Alec, but…
Alec Lightwood: Where’s Magnus? He wasn’t here, was he?
Jace Wayland: I… I don’t know.
Clary Fray: We portaled in upstairs. We split up.
Alec Lightwood: Oh, God.
