Loki: Am I cursed?
Loki: What am I?
Odin: You're my son.
(Loki turns blue for few seconds...)
Loki: What more than that? The Casket wasn't the only thing you took from Jotunheim that day, was it?
Odin: No. In the aftermath of the battle, I went into the temple and I found a baby. Small for a giant's offspring. Abandoned, suffering, left to die. Laufey's son.
Loki: Why? You were knee-deep in Jotun blood, why would you take me?
Odin: You were an innocent child.
Loki: No. You took me for a purpose. What was it? Tell me!
Odin: I thought we could unite our kingdoms one day. Bring about an alliance, bring about permanent peace. Through you.
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.
