After the Scarlet Centurion waylays the Avengers on their way back from the 1940s, they find themselves in an alternative 1968 where the five original Avengers stayed together under the thumb of the Scarlet Centurion.

The story includes flashbacks and previously unknown explanations of the team’s previous trip to the ’40s in Avengers #56, and at the end of the story, Goliath uses Dr. Doom’s Time Platform to banish the Scarlet Centurion back to his time—and we think this is the only time travel that actually appears in the story (apart from the flashbacks). We don’t know what happens to the alternative 1968 (now known as Earth-689, but the traveling Avengers return to the universe that we all knew and loved in the 1960s (a.k.a. Earth-616), with their memory of the whole affair wiped by the Watcher.

Given that the Time Stone is a key element to Thanos’s master plan, you’d think that time travel would play a major part in this movie, but not so. Doc Strange does use the stone to view a slew of possible futures, but we know that’s not actually time travel. So where does the time travel come into play? Pay close attention to the final thirteen minutes of the film, after Strange announces “We’re in the end game now,” and you’ll spot one definite time travel moment and a second possible moment.

The Watcher tells us of a universe where a change in a single decision made Peggy Carter (rather than Steve Rogers become the Allies’ super-soldier. Like Steve, Peggy also managed to find her way into modern times via a technique that’s related to time travel.
