10 MCU Loose Ends That Will Mean Something In Phase 4

5. Lady Sif

We can only be told so many times that Lady Sif is off somewhere on another mission before we start to really question what the hell she's been up to. Whatever this mysterious mission is, she's missed the fall of Asgard, the decimation of her people and the destruction of half of the universe's existing life. So it must be pretty big.

When Thor: Ragnarok came and went, it was widely assumed that we would simply not get to see Lady Sif again, but there is a big opportunity coming in Phase 4 that could see her return. Taika Waititi is already giving Natalie Portman's Jane Foster the return to favour she deserves, while also pushing Valkyrie's story further, so adding Lady Sif to the story would make a lot of sense.

Perhaps we could even see Sif answering the question of who Valkyrie will choose for her Queen? Whatever the specifics, we surely must be getting another step in one of the only surviving Asgardians' stories? SURELY?!
