Such is the power of the Marvel Cinematic Universe that fans are still trying to make sense and tie together everything that happened in Avengers: Infinity War to movies that preceded it. Now, one sleuth has discovered a link to the Russo Brothers' sprawling epic trailing back to director Joss Whedon's Avengers: Age of Ultron in 2015.
A fan on Reddit uncovered what seems to be Thor unknowingly coming across the fate of the Mind Stone, which as we know from Infinity War sees Thanos claim it from Vision in Wakanda. The user references the vision Thor had while visiting the Norns and the pool he bathed in, where he foresaw the upcoming death and destruction to be caused in the MCU, including ominous hints of the Infinity Stones.
The discovery rightfully points out Thor telling Vision later on that his Infinity Stone, which of course gave life to the android, would be at the center of certain death. This deathly prophecy was fulfilled when Thanos killed the robot and places the gem in the middle of his Infinity Gauntlet. Of course, it can't be a coincidence that Thor ends up being the one next to Thanos when he snapped half the galaxy out of existence, thus bringing the Odinson's premonitions full-circle.
Directed by Joe and Anthony Russo, Avengers 4 arrives May 3, 2019.
