Asmodeus: In the centuries since you've banished me, not a day has passed when I haven't felt the pain of losing you. I took your magic... to bring you closer. That was wrong. All I want is another chance to be your father again.
Magnus Bane: Too late.
Asmodeus: I won't take no for an answer.
Magnus Bane: You don't really have a choice. (portals away)
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.
Asmodeus: Why would I ever give you the means by which Lilith could be banished back here to lord over us all? Edom may not be Marseille, but it's a hell of a lot less miserable with her gone.
Magnus Bane: Name your price.
Asmodeus: "There is a time when we all must return to live in the houses of our fathers." Rule beside me.
Magnus Bane: I never should have come.
Asmodeus: Say what you will about the time we spent together, but you have to admit, you enjoyed every minute of it.
Magnus Bane: I was a child! Father... I have never once come here to ask you for anything. There must be something else I can give you.
Asmodeus: Actually, my son... there is.
