New details and possible spoilers for "Thor: Ragnarok" will feature the location of the Soul Stone and Hela teaming-up for Thanos in "Avengers: Infinity War".
It seems that location for the last Infinity Stone has been revealed as the Soul Stone is said to possibly appear during the events of "Thor: Ragnarok". Moviepilot creator Michael Eldred created the T.H.A.N.O.S. theory, which speculated the locations of each Infinity Stones in the Marvel Cinematic Universe, and it appears that theory has some how became plausible after the events of "Doctor Strange" film.
The letter "N" in the theory stands for Necklace which purtains to the Time Stone as the Eye of Agamotto in "Doctor Strange". The rest of the letters refer to the Tesseract (Space Stone), Aether (Reality Stone), the Ord (Power Stone) and Loki's Scepter (Mind Stone).
All that remains is the letter "H" which points out were the Soul Stone is located and it theorized before that Hela, the Goddess of Hel (Cate Blanchett) has it, while others speculate that the stone is inside Thor's hammer Mjolnir, which fits since H could be "Hammer".
However, a new evidence for the Soul Stone has been revealed online that the Asgardian gatekeeper Heimdall (Idris Elba) is secretly holding the Soul Stone due to the idea that his eyes are a similar color to the stone, and his power to see all the souls of the nine realms is derived from it, ComicBook reported.
While that theory has some problems namely, the Asgardians giving away the Reality Stone to the Collector because they only wanted to keep one stone, The Tesseract, it iss not an impossible theory that Heimdall kept his possession of a stone a secret from all Asgardians, with the likely exception of Odin Allfather (Anthony Hopkins).
In other news, Hela will likely return in "Avengers: Infinity War" as she will likely double her role as the embodiment of death in the MCU. She will be teaming with the Mad Titan Thanos (Josh Brolin) as he wants to destroy the universe to win Hela's affection, LRM reported.
Hela is the main villain in "Thor: Ragnarok" and will likely trigger the events on Asgard setting up the stage for the apocalyptic event. Thor (Chris Hemsworth) is tasked to find an ancient weapon that could stop the cycle of Ragnarok from ever happening in Asgard, alongside Valkyrie (Tessa Thompson).
There are also hints that Thor along with Loki (Tom Hiddleston) will be in New York searching for their father Odin Allfather (Anthony Hopkins), who has become a homeless person. In addition, several hints indicate that Doctor Stephen Strange (Benedict Cumberbatch) will have a cameo in the sequel.
Thor will be teaming up agains with Tony Stark/Iron Man (Robert Downey Jr.), Steve Rogers/Captain America (Chris Evans) and the rest of the Avengers to stop Thanos from collecting all Infinity Stones in "Infinity War".
"Thor: Ragnarok" is scheduled to be release on Nov. 3, 2017.
