Magnus Bane: You want to know what it's like when your parents are good churchgoing folk and you happen to be born with the devil's mark? (points to his eyes) When your father flinches at the sight of you and your mother hangs herself in the barn, driven mad by what she's done? When I was ten, my father tried to drown me in the creek. I lashed out at him with everything I had... burned him where he stood. I went to the fathers of the church eventually, for sanctuary. They hid me. They say that pity's a bitter thing, but it's better than hate. When I found out what I was really, only half a human being, I hated myself. Anything's better than that.
Alec Lightwood: It wasn't your fault. You can't help how you're born.
Magnus Bane: Come in. And try not to murder any of my guests.
Jace Herondale: Even if one of them spills a drink on my new shoes?
Magnus Bane: Even then. (Magnus plucks out stele from Jace's hand, surprising him) As for this, (slides the stele into Jace's jeans pocket) keep it in your pants, Shadowhunter.
Magnus Bane: Is the Lightwood family ring supposed to mean something to me?
Maryse Lightwood: It would if he had given it to you the other night at dinner when he planned to.
Magnus Bane: Oh, my God... then... why break my heart?
Maryse Lightwood: Magnus, when exactly did your magic return?
(Realization hits Magnus's face)
Brother Zachariah: I owe you my life, and I would do anything to help you. For that very reason, I must refuse your request.
Magnus Bane: How is that helping? I can't do this on my own!
Brother Zachariah: You can. Pull the memories from your mind and send them to oblivion. You have the magic. You simply don't have the heart. Because deep down, you know you'll regret it.
