Avengers: Infinity War - 15 Things Marvel Want You To Forget First

13. Jane Foster

When It Mattered

For the first two Thor movies, there was no separating Thor and Jane Foster. They were friends, lovers, allies and they fought together, loved together and almost died together.

More importantly than any of that romantic nonsense, Foster was also the world's leading authority on the multiverse (or the science of it), which made her a really valuable asset to S.H.I.E.L.D. and the Avengers.

But Now...

Well, thanks to Natalie Portman's post-Dark World frustrations, Foster didn't come back for Age Of Ultron or Thor: Ragnarok and it was revealed they'd split up. Thor looked glum for about 17 seconds and then fell in love with Valkyrie. End of Foster's importance, right?

Well, no, not exactly, because multiverse theory is going to be MASSIVELY important in Avengers: Infinity War and its sequel (both Ant-Man & The Wasp and Captain Marvel will deal with it), so having someone as in-the-know as her on the side of good might have been pretty useful. Shame that.
