The Flash: 2 options for the mystery girl from Crisis on Earth-X wedding

Dawn Allen

The consensus will be Dawn Allen, the comic book daughter of Barry and Iris. She’s one-half of twins, with the other being Don Allen. These two inherited Barry’s speed, using it for heroic purposes and became the Tornado Twins.

It should be noted, that in the comics, Dawn and Don never met Barry, who died in Crisis on Infinite Earths. This saw the titular hero of The Flash disappear into another dimension. Could this be what the newspaper that first appeared in season 1 of The Flash teased, referencing Barry “vanishing in a crisis?” It’s dated for 2024.

This makes it possible that Dawn went back in time, with a desire to witness her father’s wedding and see him alive. That can eventually lead to a warning about this “vanishing in a crisis” theory that’s lingered since season 1. Given the light tone of season 4, Barry and Team Flash may play it off as nothing, as season 3 just dealt with a “Changing the Future” storyline. Instead, it can be referenced in a future season.

Dawn will be the favorite, as the comic book history supports her being this mysterious girl. However, she’s not the only option that has West-Allen ties.
