Loki: I am Loki, of Asgard and I am burdened with glorious purpose.
Erik Selvig: Loki, brother of Thor.
Nick Fury: We have no quarrel with your people.
Loki: An ant has no quarrel with a boot.
Nick Fury: Are you planning to step on us?
Loki: I come with glad tidings of a world made free.
Nick Fury: Free from what?
Loki: Freedom. Freedom is life's great lie. Once you accept that, in your heart, you will know peace.
Nick Fury: Yeah, you say "peace," I kind of think you mean the other thing.
Loki: Almighty Thanos, I, Loki, Prince of Asgard... Odinson... The rightful king of Jotunheim, God of Mischief... Do hereby pledge to you, my undying fidelity. (Loki tries to stab Thanos)
Thanos: "Undying"? You should choose your words more carefully.
Loki: You... will never be.... a god. (Thanos chokes him and eventually snaps his neck)
Thanos: No resurrections this time.
Thor: This place is perfect for you. It's savage, chaotic, lawless... Brother, you're gonna do great here.
Loki: Do you truly think so little of me?
Thor: Loki, I thought the world of you. I thought we were gonna fight side by side forever. But at the end of the day, you're you and I'm me. I don't know, maybe there's still good in you. But let's be honest, our paths diverged a long time ago.
Loki: Yeah. It's probably for the best that we never see each other again.
Thor: It's what you always wanted.
