WARNING: The following article contains spoilers for Thor: Ragnarok, in theaters now.

Eagle-eyed fans of the Marvel Cinematic Universe have noticed an inconsistency when it comes to the Infinity Gauntlet. The item, containing the six Infinity Stones and famously wielded by Thanos, was seen in Odin's treasure vault in the first Thor film; the next time the Gauntlet is shown is in the post-credits of Avengers: Age of Ultron, where it seems to be in Thanos's possession.

In the past, Marvel Studios producer Kevin Feige has claimed that there are multiple Gauntlets in the MCU. Thor: Ragnarok offers a simpler explanation, however -- the one Odin has out on display is simply... a fake. In an interview with Slashfilm, Feige explained the reveal.

Originally, the studio had no idea it would tell an Infinity Gauntlet story. "Going all the way back to Phase One, where Infinity War was a barely a glint in our eye, we were working on Avengersand trying to get just put that all together for the conclusion of Phase One," Feiege explained. "And it’s in one shot. It’s in one shot in the background. Pretty quickly after that, within a couple years, we were like, well that’s clearly not the Gauntlet. The Gauntlet can’t be in there. And we had an internal Marvel theory that it was fake..."

The reveal not only served the plot of Ragnarok by helping to establish Odin as something of a faker, it also gave the studio the chance to retcon Odin's Gauntlet. "So Odin put a fake and he goes, it’s fine, I got it. Look, it’s fine, it’s in our vault, don’t worry about it. And it’s not until Hela goes down there. It was fun being back in that vault, by the way, for the first time since Thor 1. It was just the opportunity to call it a fake."

Feige seems pretty happy that die-hard fans caught on, saying, "So for people like yourself, and like all of us at Marvel Studios who were paying attention, that answers that question. And for people who have no idea that an out-of-focus Infinity Gauntlet appeared in the back of Thor 1, it just showcases her knowledge and her sort of disgust with the way Odin had handled things on her way to the true power that is below the surface."

In theaters now, director Taika Waititi’s Thor: Ragnarok stars Chris Hemsworth as Thor, Mark Ruffalo as Hulk, Tessa Thompson as Valkyrie, Tom Hiddleston as Loki, Cate Blanchett as Hela, Jeff Goldblum as The Grandmaster, Idris Elba as Heimdall, Anthony Hopkins as Odin, and Karl Urban as Skurge.
