Re: Thor 2 Dark World news, speculation and pictures possible Spoilers - Part 7
When Jane and Sif merged giving Jane the ability to fight really well. She kicked Troll and Commie ass alike and got an amnesiac Odin's memories back (oh the irony!) and he still didn't consider her worthy. He told Thor that he couldn't set foot in Asgard Until he had left Jane.
Odin is Jane's worst enemy and when they meet it is always explosive. They represent the two sides of Thor and his responsibilities so when they're fighting its the fight between Asgard and Midgard in Thor himself.
WHAT WOULD DARTH VADER DO?
