Heimdall: Tell me, Loki, how did you lead the Jotuns into Asgard? 
Loki: Do you think the Bifrost is the only way in and out of this realm? There are passages between worlds to which even you, with all your gifts, are blind. But I have need of them no longer, now that I am king. And I say, for your act of treason, you are relieved of your duties as gatekeeper and no longer citizen of Asgard! 
Heimdall: Then I need no longer obey you!
