Thor: Where is the Tesseract?
Loki: I missed you too.
Thor: Do I look to be in a gaming mood?
Loki: Oh, you should thank me. With the Bifrost gone how much dark energy did the Allfather have to muster to conjure you here? Your precious Earth.
Thor: I thought you dead.

Loki: I am a king!
Thor: Not here! You give up the Tesseract! You give up this poisonous dream! You come home.
Loki: I don't have it. You need the cube to bring me home, but I've sent it off I know not where.
Thor: You listen well, brother. I...

Loki: I'm listening.
