Magnus: *With his hands tied behind his back, unable to effectively direct his power* Is this about that time I wanted to turn you into a human coat rack? Because I meant it in the most flattering way possible.
Magnus: What? I said you'd make a PRETTY place to hang hats.
Magnus: So it's not about that. *shrug* I just figured that madness knows no bounds and grudges run deep in some people. Anyway, it's obvious that you really don't have Alexander chained up in your house. What's the point in luring me to your secret lair? If you wanted a date, you could have just asked. I would have turned you down, but still...
Sebastian: *laughs* For somebody that's supposed to be old and wise, you're awfully stupid. You love him so much, you would trade your life for Alec's. But would he do the same for you? No. You're here because he had the chance to trade Clarissa's life for yours. And in not doing so in a timely fashion, he sent a very loud and clear message.
Magnus: That he doesn't negotiate with terrorists? I don't blame him.
Sebastian: *scoff* No. That a Shadowhunter's life is more valuable than a Downworlder's life. That Alec considers you expendable.
Sebastian: I must say, I'm quite pleased that the brats of the Institute still have a shred of dignity. However, I still want my sister returned to me. I'm holding you as collateral.
Sebastian: What's the matter, cat got your tongue? You have its eyes and it wants them back. Maybe you should let me gouge them out in exchange for your voice. *laughs*
Magnus: You're not very pretty when you're behaving like a spoiled child who's not getting his way.
Sebastian: *smacks Magnus across the face with the back of his hand*
Magnus: *mockingly:* Bitch, don't make me take off my earrings.
Sebastian: *laughs maniacally* You're cheeky. I like that. You have the gall to call me a bitch - if only you knew whose blood runs in my veins.
Magnus: *bored sigh* Again. Spoiled child. Not attractive. *Facetiously:* "Do you know who my father is?!"
Sebastian: *smacks again, hard enough to draw blood* As one of the Children of Lilith, you should learn to respect the actual progeny of Lilith. You are nothing. You are a pawn in the games of Men. You are just another pet to the Nephilim, doing tricks for them like a trained dog. When they return what is mine, I'll let you run back to them like a good pet.
Magnus: I know I'm wearing a leather collar around my neck, but it's a fashion statement. I'm far from their lap dog. *remains defiantly aloof, but inwardly doubts himself*
