The Flash executive producer shoots down Mystery Girl fan theories

Fans have been debating the identity of The Flash's Mystery Girl (played by Jessica Parker Kennedy) ever since her first appearance in the epic Crisis on Earth-X crossover event. Whoever she is, it would appear that none of the theories making the rounds have actually zeroed in on her true identity.

That’s what The CW's Flash executive producer Todd Helbing revealed in a recent interview with TV Guide. When asked if fans had guessed Mystery Girl’s identity yet, Helbing said: “Not really, no. Every year there's theories all over the place about what we're doing and some of them get pretty close, some of them they hit like one part of it but they don't get other parts, so it's fun to read. I don't think anybody ever is going to guess exactly what it is.”

The first time Mystery Girl showed up in Central City was during Barry and Iris’s wedding where she sought out Barry dressed as a caterer and offered some words of encouragement, reminding him to say “I Do.” When Barry asked if they’d met before, Mystery Girl replied they hadn’t. She then showed up two more times in Central City.


In “The Elongated Knight Rises,” she runs into Ralph and Cisco at CC Jitters where we see her write something in her diary in the same mysterious language Barry used after he was released from the Speed Force. Then in last week’s “Enter Flashtime,” she literally bumps into Harry and Caitlin (in CC Jitters again) and nervously lets slip the name of Caitlin’s alter ego Killer Frost (while making it seem she's referencing the coffee drink of the same name).

Now, the two prevailing theories have been that she either is Barry and Iris’ daughter from the future, Dawn Allen, or Jenni Ognats. Jenni is Dawn’s daughter and Barry and Iris’ granddaughter. The character was also a Legion of Super-Heroes team member known as XS. The most recent theory, however, has been that she’s actually the new Earth-3 speedster Jay Garrick mentioned in last week’s episode of The Flash. But, it stands to reason neither theory is entirely right.

The Arrowverse has a penchant for borrowing elements from the comics and combining them with fresh ideas, meaning she could be an entirely new character, or the combination of multiple comic characters. 

With Helbing having apparently debunked those theories in a flash, the mysterious identity of Mystery Girl just got even more mysterious. Give us your best theory below.
