How we cite our quotes: All quotations are from Thor.
Quote #7
LOKI: I will conceal you, and a handful of your soldiers, lead you into Odin's chambers and you can slay him where he lies.
LAUFEY: Why not kill him yourself?
LOKI: I suspect that the Asgardians would not take kindly to a king who had murdered his predecessor.
This is typical bad guy stuff, and we can't say we're surprised. But sneaky cuts both ways, and in this case, it's more compacted than that. Loki isn't trying to betray Odin: he's setting up Laufey, as a way of weakening Asgard's enemies. In his own sick way, he's doing the right thing: the thing Thor originally wanted to do. And if Thor hadn't caught wise at just the right time, he likely would have made it happen…
Quote #8
HEIMDALL: You would defy the commands of Loki, our king? Break every oath you have taken as warriors, and commit treason to bring Thor back?
SIF: Yes.
HEIMDALL: Good.
Heimdall, stickler for the rules, is able to eel around his rigid ethics system in order to do the right thing. It's interesting the ways he sticks to the letter of his duty while ignoring the spirit…suggesting that he still won't break his word to help Thor. He's just found a way around it.
Quote #9
ERIK: I still don't think you're the god of thunder. But you ought to be.
Erik's first admission that Thor might actually be a better guy than he first thought is important, since it happens at the same time as Thor's moral awakening. It suggests, very subtly, that Thor always had the capacity to be a hero in him. He just needed a swift kick in the rear to bring it up.
