Odin: But the day will come when one of you will have to defend that peace.
Young Loki: Do the Frost Giants still live?
Young Thor: When I'm king, I'll hunt the monsters down and slay them all! Just as you did, father.
Odin: A wise king, never seeks out war. But...he must always be ready for it.
[he walks away and the boys run to catch up with him]
Young Thor: I'm ready, father.
Young Loki: So am I!
Odin: Only one of you can ascend to the throne. But both of you were born to be kings!
(In the trailer)
Loki:I will destroy their kind
Thor: You can't kill an entire race
Loki:Then die with them!
Thor: It's unwise to be in my company now, brother. This was to be my day of triumph.
Loki: It'll come. In time.
Loki: If it's any consolation, I think you're right. About the Frost Giants, about Laufey, about everything. If they found a way to penetrate
Asgard's defenses once, who's to say they won't try again. Next time with an army.
