Avengers 4: 11 Things It Must Avoid

11. The "Dusted" Avengers Are Sent To Soul World

Considering the rather mysterious nature of Thanos' (Josh Brolin) finger snap and the subsequent disintegration of half the universe at the end of Infinity War, there are some fans who believe that those who turned to dust didn't actually die.

Rather, the theory suggests that the finger snap activated the Soul Stone, which consequently trapped those affected inside the "Soul World".

If this turns out to be true, it would undermine Infinity War's ending quite a bit, because regardless of the fact that the dustings will clearly be undone in Avengers 4, in that moment those characters were presumably all wiped out of existence.

For them to simply be stranded inside the Soul World would retroactively strip Infinity War's finale of much of its emotional impact.

Will It Happen?: The Russo brothers have confirmed that the orange-tinted locale we briefly glimpsed post-snap, where Thanos was temporarily reunited with young Gamora, was indeed the Soul World, which at least adds more fuel to the fire.

However, the Russos and writers Christopher Markus and Stephen McFeely have also made pains to assure fans that Infinity War's finale won't be quickly undone in Avengers 4, so it seems far more likely that the snap did indeed "kill" everyone it turned to dust.
