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?
Alec Lightwood: You know, now’s not a really good time for me. Another time? Gotta go.
Magnus Bane: Playing hard to get. I love a challenge.
Alec Lightwood: At Magnus’s. The demon… image of you.
Jace Wayland: That? You love me… so? I love you, too, Alec. Come on, man. We’re parabatai. We’re brothers. We’ve spent almost our whole lives together. How could we not love each other? This is what’s been bothering you? Seriously?
Alec Lightwood: Yeah. You’re right. That’s true. I just thought you’d think that…
Jace Wayland: What? Whatever, okay.
