Avengers: Infinity War - 15 Last Minute Rumours You Must See
13. Tony Stark Has The Soul Stone
The Rumour: Though most of the evidence points to the Soul Stone being hidden in Wakanda, what if the Russo brothers are swerving us all, and it's actually (somehow) in the possession of Tony Stark (Robert Downey Jr.)?
How Likely Is It?: The main fuel for this theory is a recent piece of promotional art for Infinity War, which depicts the six Infinity Stones while focusing on the Avenger who is most intimately tied to each respective stone (for instance, Cap [Chris Evans] and the Space Stone, Star-Lord [Chris Pratt] and the Power Stone, Vision [Paul Bettany] and the Mind Stone etc).
Curious it is, then, that Iron Man is the focal figure for the Soul Stone. Of course, it's still a fairly vague link, and this could simply mean that he stumbles across the final Infinity Stone somehow (perhaps even on Wakanda) rather than him secretly harbouring it somewhere.
The MCU loves to subvert expectations and toy with spoiler-hungry fans, though, so there's every chance this was just a cheeky not-hint, to be honest. Again, it's hard to be convinced either way. 5/10
