Volstagg: How did the guard even know? 
Loki: I told him. 
Fandral: What? 
Loki: I told him to go to Odin, after we'd left. He should be flogged for taking so long, we should never have reached Jotunheim... 
Volstagg: YOU told the guard? 
Loki: I saved our lives, and Thor's! I had no idea Father would banish him for what he did. 
Sif: Loki, you must go to the All-Father and convince him to change his mind. 
Loki: And if I do, then what? I love Thor more dearly than any of you, but you know what he is. He's arrogant, he's reckless, he's dangerous! You saw how he was today. Is that what Asgard needs from its King?
