Jessica Parker Kennedy Teases the Return of Her Mysterious 'The Flash' Character

While The CW's "Crisis on Earth-X" crossover left fans with plenty of unanswered questions, none might be quite as intriguing as the identity of the crossover's mysterious waitress (played by Jessica Parker Kennedy).

In a recent interview with Bustle, Kennedy teased what's in store for her mystery character, who was introduced in the Supergirl hour of "Crisis." While she was vague on the details, she hinted that she will return to the world of The Flash in some way.

"I'll be around." Kennedy revealed. "You'll see me at least one more time, I can tell you that."

As fans will remember, Kennedy's character was shown having a conversation with Barry Allen/The Flash (Grant Gustin). The encounter was delightfully awkward, with Kennedy's "Mystery Girl" revealing that she was excited to be there and reminded Barry to say "I do".

Considering how out of place the scene seemed in such a high-octane crossover, fans have been wondering exactly what Kennedy's arrival - especially at Barry and Iris' wedding - could mean for the show. And according to Kennedy, her next Arrowverse appearance will help provide some sort of answer.

"You'll see me again on the show and things will make more sense," Kennedy explained.

As of right now, the identity of Kennedy's character seems to be narrowed down to two potential suspects, Dawn Allen and Jenni Ognats, Barry and Iris' daughter and granddaughter from the future. While it's hard to pinpoint exactly how either possibility would effect The Flash, Kennedy says that the role was offered to her in a very interesting way.

"I got brought into the office and the producers had kinda let me know what their idea was, and it was so cool because it was such a personal meeting." Kennedy revealed. "They told me about it, and I was really excited. It's a very cool concept, and you know, it's very secretive and hush hush."

But as it turns out, those involved with the show are going above and beyond to keep the identity of Kennedy's character a secret, something that even bled into the behind-the-scenes work of "Crisis."

"No, it's really funny." Kennedy added. "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."

Fans will hopefully start to get answers about The Flash - and how Kennedy's character will officially enter the show - when it returns from midseason hiatus on January 16th, 2018.
