Chris Hemsworth says in the build-up to Avengers: Infinity War, the location of the final Infinity Stone will be revealed soon. The first Infinity Stone — the Space Stone — was introduced back in Captain America: The First Avenger. Since then, The Avengers (Loki’s scepter/Mind Stone), Thor: The Dark World (Aether/Reality Stone), Guardians of the Galaxy (The Orb/Power Stone), and Doctor Strange (Eye of Agamotto/Time Stone) have each introduced one, leaving only the Soul Stone to be revealed.
As the final piece of the Infinity Gauntlet, fans have been left wondering when they will see the stone and where it has been hiding. As it turns out, Hemsworth already knows the answers, saying audiences will soon be on the same page.
Hemsworth appeared at the Supernova Comic-Con in Australia and was asked about his knowledge of the final Infinity Stone. Thor has been searching for answers since Avengers: Age of Ultron, so it should come as no surprise that, according to Reddit user lawrensaw, the actor said the stone’s location will be revealed “real soon.”
“Real soon” raises its own questions, as Marvel has two more films pending theatrical release this year alone. Spider-Man: Homecoming seems unlikely, so Hemsworth’s response may serve as indication that Thor: Ragnarok will reveal the final Infinity Stone. Fan theories have given Heimdall (Idris Elba) a prominent role in the reveal, with many thinking his abilities are a result of the Soul Stone. Others theorize Hela or the Valkyrie may play a role in bringing the stone into the universe.
If it is not Ragnarok, then Black Panther is the last place it could be hiding. Like Homecoming, an Infinity Stone in the Earth-bound film would be a surprise. However, if Wakanda is somehow connected to the Soul Stone, it would go a long way in explaining why there are multiple Black Panther cast members appearing in Avengers: Infinity War.
If neither Ragnarok nor Black Panther introduce the Soul Stone, that leaves the next Avengers film. Thanos cannot fully realize the power of the Infinity Gauntlet without it, which could mean locating and obtaining the Soul Stone is actually a part of the plot to Infinity War. At the moment, there’s no telling where the final Stone will pop up in the MCU, but one thing is for certain: fans don’t have long to wait to find out.
