It is an impressive cage, one not I think built for me.

Nick Fury: In case you try to escape, if you so much as scratch that glass. Thirty thousand feet, straight down in a steel trap. Ant, boot.
Loki: It is an impressive cage, one not I think built for me.
Nick Fury: Built for something a lot stronger than you.
Loki: Oh I’ve heard; the mindless beast, makes play he’s still a man. How desperate are you? That you call on such lost creatures to defend you?
Nick Fury: How desperate am I? You threaten my world with war, you steal a force you can’t hope to control, you talk about peace, and you kill ’cause it’s fun. You have made me very desperate. You might not be glad that you did.
Loki: Ooo, it burns you to have come so close. To have the Tesseract, to have power. Unlimited power. And for what? A warm light for all mankind to share? And then to be reminded what real power is.
Nick Fury: Well, let me know if ‘real power’ wants a magazine or something.
