It seems time will not be on the side of the Avengers when they head out of Avengers: Infinity War.

Sebastian Stan, who plays the Winter Soldier in the Marvel Cinematic Universe, took to his Instagram account to post a new behind-the-scenes picture from Avengers 4. Although the actor's post was meant to be a comical nod to Captain America: Civil War's now infamous "December 16, 1991" mission report, the photo also managed to reveal an intriguing location that will make a return in the fourth Avengers film.

We can clearly see that the actor is standing in Tony Stark's Hall of Armors, a location that was last seen in flames in Iron Man 3, when Stark's mansion was blown to bits. Iron Man's Mark II, Mark V and Mark VII armors were all destroyed and yet, they seem to be back in pristine condition. Seeing the return of this iconic location is quite curious, and it makes us wonder if there is any truth to the rumors that Avengers 4 will feature extensive flashback sequences.

After all, there have already been reports of a scene set in the days of World War II, as well as a picture featuring Wasp actress Evangeline Lily sporting her haircut from the first Ant-Man film. Now, with the return of Hall of Armors, it seems all but confirmed that the Avengers will travel back in time in some capacity. But how, and why? That remains to be seen.
