Alec Lightwood: Magnus sacrificed everything so I could feel whole. And now I have the chance to do the same for him.
Izzy Lightwood: He wouldn't want this. He loves you so much.
Alec Lightwood: I know. But I'm not the first person he's loved, and I won't be the last. Breaking up is gonna hurt like hell, but it's the kind of hurt he can recover from.
Izzy Lightwood: But what about you? Can you recover?
Alec Lightwood: You would do anything to break Clary's connection with Jonathan, right?
Jace Herondale: Yeah. Yeah, of course.
Alec Lightwood: So, hypothetically, what if you could? But, as a consequence, you could never see her again?
Jace Herondale: That's a little dark.
Alec Lightwood: Just humor me. Would you do it?
Jace Herondale: Now that I've lost her once, I don't think I could ever go through that again. It's selfish, I know. But...
Alec Lightwood: No. I get it.
Asmodeus: Immortals aren't meant to grow wrinkled and grey. In time, Magnus will come to resent you, until the bitter end.
Alec Lightwood: I'm here to prevent that future. To get him his magic and his immortality back.
Asmodeus: Fine. I'll restore both. Under one condition. End your relationship.
Alec Lightwood: What?
Asmodeus: You are the source of all his suffering. You make him vulnerable, weak. With you, he'll never reach his full potential.
Alec Lightwood: You're wrong. We love each other. I wouldn't just abandon him.
Asmodeus: Then I'm afraid you will be the death of him.
Magnus Bane: Please, Alexander. Don't make me pretend this is just a phase, because it's not. What I'm feeling now, it may never pass. For as long as I live. I should go. I've probably killed both our appetites.
Alec Lightwood: Stop. Stop, listen. Magnus, I... I love you. Can you just... I just wanna help.
Magnus Bane: I know you do, but you can't...
Alec Lightwood: Listen, you have to... Stop!
Magnus Bane: Alec, let me go.
Alec Lightwood: Please, stop! Listen to me.
Magnus Bane: You can't help me...
Alec Lightwood: Listen to me for second...
Magnus Bane: You can't!
Alec Lightwood: Stop, just let me be here with you.
Jace Herondale: You're nervous. Why are you nervous?
Alec Lightwood: What? I'm... I'm not nervous.
Jace Herondale: Yes, you are. What's going on?
Alec Lightwood: I'm, uh, proposing to Magnus tonight.
Jace Herondale: What? Are you serious? Alec, congratulations. You're about to make Magnus the happiest man in the world.
Alec Lightwood: Yeah. I just want everything to be perfect.
Jace Herondale: Listen to me. It's not gonna matter what you do or what you say when he realizes he gets to spend the rest of his life with you.
Alec Lightwood: There's actually something I wanted to talk to you about.
Maryse Lightwood: What is it?
Alec Lightwood: Um... Magnus had a little health scare. He's okay. Everything's fine. But, when it happened, it made me realize how much he means to me. And that I... can't live without him.
Maryse Lightwood: That's what love is. I'm so happy you two found each other.
Alec Lightwood: Me too. And I need the family ring. I'm gonna ask Magnus to marry me.
Alec Lightwood: Lorenzo... thank you.
Lorenzo Rey: Yes, well... I hope you know this changes nothing. I'll be keeping the apartment.
Magnus Bane: Oh, fine. I have everything I need right here.
Alec Lightwood: Why do you hate him so much?
Lorenzo Rey: It's simple. All my life, I've had to sit by and watch while the world lavished praise on Magnus Bane. The Prodigy. The High Warlock who could do no wrong.
Alec Lightwood: Green isn't becoming on you, Lorenzo.
Lorenzo Rey: You have no idea how hard I've had to work for everything that I have. That man was born with a silver spoon in his mouth. His celebrity is not based on talent. It's nepotism.
Alec Lightwood: Lorenzo, you're right about one thing. Magnus is beloved. And when word gets out that you wouldn't help him, purely out of jealously... how do you think the other warlocks are gonna feel?
Lorenzo Rey: I guess we'll find out, won't we?
