Jane Foster starts off the third act in rough shape. Yes, she has the power of The Mighty Thor and can wield an absolutely bonkers shrapnel-shooting version of Mjolnir, but instead of curing her stage 4 cancer, her powers are draining the remaining life from her.

Thor begs her to stay out of the final fight, not because she isn’t powerful, but because the exertion will certainly push her past her limits. Yes, he could certainly use her help to rescue the stolen Asgardian children — a quest that, if he fails, means the end of him and all gods everywhere, which would throw trillions of lives into chaos and make them vulnerable to the darkness they’ve been protected from since the beginning of time. But even then, it’s an easy choice for Thor.

It’s not such an easy choice for Jane, though. It’s a lot to ask of any person to sit idly by while someone they love is in danger, let alone someone that has an all-powerful hammer and super strength.

She chooses to enter into the fight, knowing it’ll be her last foray. But the fate of the universe is at stake, so what the hell?

The situation for Thor is a little less complicated. Get the bad guy, don’t get stabbed by the god-killing sword, save the universe. Easy-peasy, right? His journey in the film is more about letting himself be open to love again, so we’ll put a pin in the God of Thunder for just a moment and circle back after we talk about Gorr the God Butcher.
