"Loki says, 'How much dark energy did the All-father have to muster to conjure you here?' Tom Hiddleston recalled in a recent interview with .
"The Bifrost is still down, he can’t just be riding down the rainbow bridge, Heimdall [is gone], it’s all changed since the end of 'Thor' so it’s obviously cost Odin a significant amount to get there," he explained. "I guess he’s been sent down by Odin to go and deal with this crazy cat that is his brother." Chris Hemsworth reveals that while the movie doesn't really go into the specific details of Thor's return, his time on Earth is actually limited.
"It’s not really explained, but it’s assumed that he can only be there for a window of time. Odin has had to call in some favors from around the realm. And he turns up. That or the bus," he joked.
