We’ve all seen the so-called “Mystery Girl” who has appeared in three different episodes of The Flash (I’m counting part one of “Crisis on Earth-X” to that total because let’s face it; it’s been pretty obvious from the start that she’s a Flash character), and there are multiple theories as to who she is. After Mystery Girl’s third cameo in “Enter Flashtime”, it’s all but confirmed that she is a time-traveler, but who exactly is she?

Is she Dawn Allen, Barry and Iris’ future daughter and one half of the Tornado Twins? Is she Jenni Ognats (aka XS), Dawn’s daughter and the Legion’s resident speedster? Is she some gender-swapped version of Bart Allen (aka Impulse)? Or is the future daughter of some other hero in the CW multiverse?

Personally, I think that she’s Dawn Allen. First, she shows up at Barry and Iris’ wedding disguised as one of the caterers and gives Barry a pre-wedding pep-talk. Let’s all be honest here—given Barry’s own blatant disregard for the timeline, would it be all that surprising if one of his future kids were to run back in time to check it out? Let’s just be grateful that Mystery Girl (who I will call “Dawn” from here on out) seems to have gotten out of there before the Nazis crashed the wedding.

Now, I’ll admit that this could just as easily be true for Barry and Iris’ grandkids, too. However, based on Dawn’s interactions with the other members of Team Flash, it seems like she already sort of knows them. It’s more likely that she’s Barry and Iris’ daughter, which would make the other members of Team Flash like her aunts and uncles.

If she really is Dawn, then there are several questions raised. Where is Don? Why is she in the past, particularly in what is probably the riskiest time period, what with DeVoe and all? How will her presence affect DeVoe’s plans?

First, let’s think back to the season 4 premiere, when Barry comes out of the Speed Force. Team Flash’s plan is to throw a ball with Barry’s DNA into the Speed Force and trick it into thinking that Barry is still there. Does anyone else see a problem with that plan? For one, it’s not just about the Speed Force wanting to have a speedster trapper inside it; it’s about holding up the Speed Force itself. How does one little sphere take the place of a full-grown speedster?
