Thor: We were raised together, we played together, we fought together. Do you remember none of that?
Loki: I remember a shadow, living in the shade of your greatness. I remember you tossing me into an abyss, I who was and should be king!
Thor: So you take the world I love as recompense for your imagined slights? No, the Earth is under MY protection, Loki!
Loki: And you're doing a marvelous job with that! The humans slaughter each other in droves, while you ideally threat. I mean to rule them. And why should I not?
Thor: You think yourself above them?
Loki: Well, yes.
Thor: Then you miss the truth of ruling, brother. A throne would suit you ill.
Loki: I've seen worlds you've never known about! I have grown, Odin's Son, in my exile, I have seen the true power of the Tesseract, and when I wield it...
Thor: Who showed you this power? Who controls the would be king?
Loki: I am a king.
Thor: Not here! You give up the Tesseract! You give up this pointless dream! You come home.
Pepper Potts: Is this about the Avengers? Which I know nothing about.
Tony Stark: The Avengers initiative was scrapped, I thought. And I didn't even qualify.
Pepper Potts: I didn't know that either.
Tony Stark: Apparently I am volatile, self-obsessed, and don't play well with others.
Pepper Potts: That I did know.
