The Avengers: Endgame trailer dropped on Friday to an earth shattering response and fans are already pouring through the details, breaking down everything they saw. One of the most exciting theories has been the possibility of time travel, something that was largely hinted at in the set photos that leaked earlier this year. A possible time travel theory involving Scott Lang has already gotten fans excited and now we have another one featuring our very own Captain America.

One of the final shots in the Avengers: Endgame trailer before the title reveal involves Captain America looking at his compass. Containing a picture of Peggy Carter, the compass is held by Steve Rogers as Widow hopes for their plan to succeed, to which Rogers sincerely hopes, stating that he wouldn’t know what he’d do if it didn’t, reeking of desperation to save the lost heroes. As it turns out, there’s one more time Cap saw his compass in the Marvel Cinematic Universe and it wasn’t a pleasant one.

At the ending of Captain America: The First Avenger, Cap looks at his compass and the image of Peggy Carter therein one last time before he sacrifices himself by steering the Red Skull’s ship into the ocean waters. He is then discovered by S.H.I.E.L.D. 70 years later and wakes up in a completely different time.

The bottomline? The last time Cap saw the compass, he ended up being displaced in time. He looks at the compass again in the Avengers: Endgame trailer. It could very well mean nothing, or it could very well be an extremely subtle, obviously overlooked hint of Cap about to be displaced in time once again, sort of confirming or at least hinting at time travel. To state it in clearer words: Captain America and Black Widow might travel back in time with some other remaining Avengers to undo Thanos’ snap and restore balance to the universe. I mean, if that doesn’t look like a time-travel theory, I don’t know what does.

As again, the possibility with such speculation is that it either lands bang-on, or it ends up being a complete miss. Regardless, the possibility itself is quite enticing, which is why us fans love theorizing. Don’t hesitate to let me know what you think of this theory in the comments below.
