How we cite our quotes: All quotations are from Thor.
Quote #7
THOR: You must return to Asgard. You have to stop Loki.
Thor's acceptance of his exile extends even to the fact that Asgard is in danger. That's dedication.
Quote #8
THOR: You can't kill an entire race!
LOKI: Why not? And what is this newfound love for the frost giants? You, could have killed them all with your bare hands!
THOR: I've changed.
This is important, because it means that Thor's exile serves a purpose beyond punishment. It's a learning tool…which Odin probably intended all along.
