In Asgard, Loki betrays and kills Laufey, revealing his true plan to use Laufey's attempt on Odin's life as an excuse to destroy Jotunheim with the Bifröst Bridge, thus proving himself worthy to his adoptive father. Thor arrives and fights Loki before destroying the Bifröst Bridge to stop Loki's plan, stranding himself in Asgard. Odin awakens and prevents the brothers from falling into the abyss created in the wake of the bridge's destruction, but Loki allows himself to fall when Odin rejects his pleas for approval. Thor makes amends with Odin, admitting he is not ready to be king; while on Earth, Jane and her team search for a way to open a portal to Asgard.
In a post-credits scene, Selvig has been taken to a S.H.I.E.L.D. facility, where Nick Fury opens a briefcase and asks him to study a mysterious cube-shaped object, which Fury says may hold untold power. An invisible Loki prompts Selvig to agree, and he does.
