When Hela first appears to Thor and Loki, she steps through a portal crawling with greenish-black energy. What’s unclear to me is the nature of the portal.
- The fact that the color scheme matches Hela’s strongly suggests that it’s something she did. But if it’s a facet of Hela’s powers, why was Thor so worried that she’d get swept up in the Bifrost (she could just make a portal to Asgard)? And why not use it all in the rest of the film?
- If it’s not Hela’s doing, why would she appear where Thor and Loki were? Wouldn’t she just be stuck in…wherever? Why would a portal bring her to Norway, of all places?
What exactly is going on with that portal? Is it Hela’s doing, or something else?
