Where/what do you think the Soul Gem is (MCU theories)?

IMO: Heimdall. That theory has by far the most evidence. Plus, it would complete the theory that the infinity stones are meant to spell Thanos. Although, to be fair, so would Hela.

Despite growing fan theories that it's in Wakanda, I doubt it. I just don't think Marvel would introduce an infinity stone in a relatively grounded movie.

The Eye

It's in Caps biceps.

Heimdall.

Mjolnir doesn't make that much sense when you think about how Odin just threw it to the Earth with the possibility of a random dude or someone looking for the soul gem getting it, I mean, that's not what you do when you have an infinity stone...

Wakanda doesn't looks good either.

Black Phanter it's a possibility, but I don't see that happening.

So, Heimdall

I think the only one that can def be ruled out is Wakanda. I see BP being a very self contained movie like Homecoming was

Heimdall he literally says he sees all kinds of souls over the universe either him or Hela or maybe Surtur will have it

It's not going to be in BP and Thor and BP are the only ones left

Just really hope it's not yet another one that's been on Earth this whole time. Like the space stone. And the time stone. technically not the reality stone, but it was accessed from Earth.

Wherever it is I expect it in Thor ragnorok not BP

Asgardisns gave aether to Collector, because they didn't want to have more than one infinity gem, so I doubt Heimdall has it.
