Jace Wayland: Come with me. We'll fight Valentine the right way... together.
Alec Lightwood: If we do that... we'll be considered traitors like Mom and Dad.
Jace Wayland: I'm begging you, my parabatai... my brother. Please, Alec, come with me.
Alec Lightwood: No.
Alec Lightwood: I'm getting married.
Magnus Bane: Whoa! That's a tad sudden, isn't it? I mean, we should at least go to dinner first...
Isabelle Lightwood: You're on Alec's side now?
Alec Lightwood: We swore to protect each other, of course he's on my side.
Jace Wayland: I'm not picking sides. Jace Wayland is Switzerland.
Alec Lightwood: I’ve done everything for my parents… for the Clave and… I’ve done everything that they’ve asked.
Magnus Bane: Maybe you should start living for yourself. Do what’s in your heart.
Alec Lightwood: I can’t believe I’m saying this. I think you’re right.
Isabelle Lightwood: Slept at Magnus' place?
Alec Lightwood: Didn't do much sleeping. I was helping treat Luke's wounds. That's all.
Isabelle Lightwood: Really?
Alec Lightwood: What?
Isabelle Lightwood: Nothing. I believe you.
Alec Lightwood: Okay, Magnus made cocktails. I'm telling you, nothing else happened.
Alec Lightwood (to Izzy): I have followed every rule. I’ve given up everything! Screw the rules. Screw them. Screw all of this.
Clary Fray: This is from when Simon and I were engaged to be married.
Alec Lightwood: You were engaged? I’m almost certain I don’t wanna hear this story…
Simon Lewis: We were eight years old.
Clary Fray: That was a whole other world ago.
Alec Lightwood (to Clary): And what’s the point of an Invisibility rune if you don’t silence your phone?
