Who Is Mystery Girl on 'The Flash'? Find Out Here!

The identity of Mystery Girl has finally been revealed and if you guessed she was Barry and Iris’s daughter from the beginning, you were…RIGHT!

However, her name isn’t Dawn, like in the comics. It’s Nora West-Allen, and at the end of The Flash‘s season finale, she confesses she made a big mistake.

“Everybody guessed right for the most part,” executive producer Todd Helbing admitted to ComicBook.com after the reveal. “I think I’ve said this at one point that they haven’t totally gotten it yet. It was basically right except for the name. They assumed that it was Dawn.”

As for that “mistake” she talked about, Todd explains that “it’s the time that she comes from and what she did. She makes this sort of big mistake at the end of the episode — you see the concern of what she’s done, and Barry certainly learned his lessons from time travel, so now it’s going to be interesting to put him on the different side of the problem and see how he can help her fix it.”

He adds that all the times she showed up mean something, which we’ll eventually find out about in the upcoming season 5.

“There’s four specific times that she came back, and you’re gonna learn about why she chose those four times and how they’re gonna play into not only the mistake that she made, but the consequences for somebody like her, a speedster traveling from the future to the past, and what that means for Barry and the team.”
