Following the first Avengers: Endgame teaser, fans have been exploring numerous theories about how the Avengers and the rest of the universe's heroes will be trying to undo Thanos' snap. Time travel has become one of the most discussed options, with many wondering if it'll be the Quantum Realm; Captain Marvel's cat, Goose; the Time Stone; or some other device Robert Downey Jr.'s Tony Stark cooks up that does the trick.

As for those who are looking for a more conventional approach to the Mad Titan, and who don't believe temporal roaming will factor in, well, one key scene from Infinity War may bolster the theory that our heroes will indeed be traversing the timestream.

The Infinity War Hint

When Tony is in Central Park with Pepper Potts, he's discussing having a family. He goes about it in a roundabout way, nervously and very much afraid of such a future commitment.

However, he tells her about his dream where they had a baby, Morgan, named after Pepper's uncle. Of course, this was interrupted by Doctor Strange and Bruce Banner, kickstarting Tony's trip to Titan and the current chain of events where he ends up marooned in space with Nebula trying to get back home.

But while many see this as a fleeting moment with Tony feeling the need to settle down even more, what if the dream about Morgan is actually the sign that time travel has already occurred?

The Multiverse Exists

This is because the dream may not have been a dream at all, but a memory from the future, or more so, an alternate future where Tony and Pepper have Morgan. The speculation is that Tony and Pepper get married and have a baby, but it doesn't happen in this current timeline of the Marvel Cinematic Universe. It's actually from a timeline where Infinity War never takes place, Tony never gets lost in space and Morgan is born.

Now, how exactly does Tony get this memory? Well, it's due to a causal loop, which is a time travel paradox where a future event (the heroes traveling back in time in Endgame and stopping Thanos from ever getting the Infinity Stones) is the cause of a past event (which means the Mad Titan never comes to Earth and Tony gets to marry Pepper), which then causes a future event to occur (Morgan's born to the happy Stark family).

Both realities would then exist in space-time continuum, but their origin cannot be determined, as one cannot occur without the other. This is why the ripple effect is felt with actual experiences from the new reality (i.e. baby Morgan being born) seeping over into the one we know at present (where Tony receives his "dream").

Aiding The War To Come

 

It's an intriguing theory, because it leaves us wondering if any other memories from the alternate future have been leaking over. Some fans are positing that Steve Rogers' dream of him and Peggy Carter dancing when Scarlet Witch toyed with his mind in Age of Ultron could also be a byproduct of this reality.

These theorists, however, also believe the vision Tony had with the Avengers dead was from the Endgame scenario where they failed against Thanos. This means other realities could encroach on the present MCU, which ties into Wanda's affiliation with the Mind Stone and the other stones. Communication between these realities may now be possible given that Scott Lang is back, who we assume can help navigate the time pockets in the Quantum Realm.

Then we've also got to factor in Wong, who might be able to save the day by creating interdimensional rifts, traveling in between realities, which may be why we're seeing set photos from the aftermath of the Chitauri invasion with Loki. What's even more important is this second reality Morgan is from (where Thanos didn't fill the Gauntlet) might offer up Infinity Stones for our heroes to use in the primary reality, and for Tony to build time travel devices.

Or Maybe... A Cop Out?

While this is all fun and dandy, like a true comic event, the average moviegoer may view this as a cop out. Expanding the MCU into the MCM (Marvel Cinematic Multiverse) might be a lot to take in and such a move might even run the risk of cheapening the battle to come against Thanos. Think of it, an alternate reality with so many weapons, heroes and, as mentioned, Infinity Stones, does come off like a get out of jail free card just to provide the Avengers an arsenal.

Fleshing out such visions from alternate realities could even end up being as silly as the Avengers: Age of Ultron scene where Thor bathed in a mystical Norn river and saw a grim future in Valhalla with his dead Asgardians. These messages in a bottle didn't register well, serving to take a straightforward storyline and make it more complex. This direction also takes away from the gravity and emotion of Thanos, further reducing how the high stakes the battle truly is.

Ultimately, we have to consider that the Morgan situation could have also been just that -- a dream. Maybe it is a smart move to deviate from foreshadowing anything, because right now the hopelessness of tomorrow is actually what makes Endgame quite an apt title; a mouth-watering prospect. Limiting the possibility of a happy future works right now in terms of the MCU narrative, so it might be in Marvel Studios' best interest to keep things confined to one reality, no matter how unhappy the story ends, because, if anything, consequence is a theme that truly has impact.
