Moments before Barry Allen and Iris West's wedding was crashed by a group of Nazis from Earth-X, a mysterious woman shared an awkward exchange with the Fastest Man Alive. While he had no clue who she was, the character definitely seemed to know Barry and his wife to be and that's led to a lot of speculation about her true identity. Could it be that she's actually their daughter from the future?
That's the prevailing fan theory but we just don't know right now. Luckily, it seems that will change because Jessica Parker Kennedy has now revealed that she's set to show up in The Flash later this year.
"You’ll see me at least one more time. I can tell you that… You’ll see me again on the show and things will make more sense." As expected, she wouldn't reveal any more details about her character but revealed that only a handful of people know her identity. "They have me listed as ‘Mystery Girl’ and I just hang out as Mystery Girl on set. Even [the costume department] are like, ‘Who are you?’ And I’m like: ‘I am Mystery Girl.' It’s been a very secretive mission and it’s been fun to be a part of."
There has to be a reason for this level of secrecy and when it was put to Kennedy that she might be either Dawn Allen (one of the Tornado Twins) or Barry's granddaughter Jenni Ognats, she simply said that both theories are "interesting guesses." Do you have any theories about who she could be?
