There is frustratingly very little we know about the direction of Avengers 4. Following the shocking ending of Avengers: Infinity War, which saw Thanos assemble the Infinity Gauntlet and snap his fingers, wiping out half of all life in the universe, only a handful of Avengers remain to protect a world that just endured its most devastating attack, ever.

However, during the shooting of Avengers 4, the return of old set pieces and costumes sparked theories that the movie would feature some form of time-travel. With such cosmic powers as the Infinity Stones involved, that is definitely in the realm of the possible, and some believe that going back in time would be the best possible way to stop Thanos and save the universe. Those theories even gained more traction during the mid-credits scene of Ant-Man and the Wasp, which featured Scott Lang trapped in the Quantum Realm with no way of getting out. However, a mention by Janet Van Dyne of a certain time vortex might have hinted at an escape for Scott, and the possibility of time-travel.

Now, Peyton Reed, the director of the Ant-Man sequel, has gone on record to state that there might be some truth to these theories. In an interview with Huffington Post, the director was asked if Ant-Man could next appear in the past of the Marvel Cinematic Universe. "Based on the science that we’ve set up in the first movie and this one," Reed explained, "I won’t rule out the possibility, because, again, we are dealing with a time vortex. That could happen."

It's definitely interesting to note that Reed brought up the time vortex in his answer, meaning that Janet Van Dyne didn't name it by accident. While this is far from a confirmation of time-travel in Avengers 4, it does add a bit of fuel to the fire. With Captain Marvel featuring an origin story for Carol Danvers in the '90s, the key to Thanos' defeat  could very well be in the past. We'll just have to wait a bit longer to find out.
