In the scene, Jane is being examined on the Asgardian version of a medical table and it becomes clear something is very wrong with her. Thor asks, “This is not of Earth. What is it? “ One of the women examining Jane tells him, “We do not know. But she’ll not survive the amount of energy surging through her.”
Jane tries to keep things light, watching one of the woman manipulate energy above her and asking if it’s a quantum field generator. When the woman gives her a fancy Asgardian term for what she’s doing, Jane asks, “Does this transfer energy from one place to another?” Told it does, she says, “It’s a quantum field generator.”
Odin enters the room and he is not happy to see Thor has brought Jane to Asgard, saying Thor defied him in doing so. Thor says she is ill and Odin yells, “She is mortal!”
Says Odin, “She does not belong here in Asgard any more than a goat belongs at a banquet table!” Jane is aghast, exclaiming, “Did he just…? Who do you think you are? “ He replies, “I am Odin, king of Asgard,” which quiets her down, as she simply says, “Well I am… not a goat.” Odin replies, “I know very well who you are, Jane Foster.” Jane is bemused, noting this means Thor talked to his dad about her.
Odin again tells Thor to bring her back to Earth, saying human doctors should help her. He signals for some of his men to take Jane away, but when they approach her, energy blasts forth from her body, knocking them back. Thor runs over to her and asks one of the medics what is happening. He’s told, “It’s defending itself.”[/align][/spoil]
