WARNING: The following article contains major spoilers for Avengers: Infinity War, in theaters now.
The history of the Infinity Gauntlet in the Marvel Cinematic Universe has been a point of contention in recent films, and every subsequent attempt to clarify the issue has only made things more complicated.
Avengers: Infinity War brought the confusion to a new level when it showed the origin of the Gauntlet, created by the dwarf Eitri (Peter Dinklage), and forcefully taken by Thanos (Josh Brolin) to reshape the universe.
Rather than clarify the Gauntlet's timeline, this revelation ultimately left fans scratching their heads about the already muddled MCU timeline. Specifically, we had already seen the Gauntlet in Asgard in sequences from Thor and Thor: Ragnarok, as well as in the Avengers: Age of Ultron post-credits scene.
Following the film's release, Infinity War writers Christopher Markus and Stephen McFeely tried to lay out the chronological order of the Gauntlet's appearances to placate perplexed fans. But in doing so, they created some new major flaws with their theoretical timeline.
Just to recap the glove's history as depicted on-screen -- when the Frost Giants attacked Asgard in Thor and entered Odin's vault, we caught a glimpse of the Gauntlet as an Easter egg. The next time we'd see it was in Avengers: Age of Ultron, where Thanos put it on, an indication he was fed up of his minions failing to procure the Infinity Stones and was now ready to do it himself. This left fans wondering if there were two Gauntlets in the MCU -- a question Thor: Ragnarok seemingly answered when Hela made it clear the one in Odin's trophy room was a fake.
When pressed for clarification, Markus said, “I think the Gauntlet was made when Loki was pretending to be Odin. Presumably, Eitri was running a relatively regular business and people would have gone there and said something. So, it hasn’t been that long.” There's a problem with this though, and thus, a big plot hole opens up.
Loki took Odin out and shape-shifted into his place at the end of Thor: The Dark World, thus assuming full rule of Asgard as we saw in Thor: Ragnarok. But if the Gauntlet was made around this time, when Loki was pretending to be king, then how could it exist in the first Thor movie which was set years before? Odin couldn't have attained a forgery of an artifact that hadn't been created yet, so Markus' explanation here doesn't add up at all.
But wait, there's more...
