WARNING: The following article contains major spoilers from “We Are the Flash,” the season four finale of The Flash. Do not read if you have not seen the episode or read at your own risk.
After she first appeared in the Arrowverse crossover, many fans had wondered who the Mystery Girl (Jessica Parker Kennedy) popping up in random places was and in Tuesday’s season four finale of The Flash, fans finally got their answer.
Towards the end of Tuesday’s finale, the mystery girl showed up once again and this time said she needed Barry’s (Grant Gustin) help. When Barry asked who she was, she revealed she was his daughter, Nora West-Allen. Yes, she is the daughter of Barry and Iris (Candice Patton).
She then revealed she is from the future and made a ‘big mistake’ she needs the team’s help with. Sounds like it runs in the family, eh Barry? And with that, the episode ends.
Earlier in the hour, Team Flash needed to stop DeVoe’s enlightenment from overtaking the Earth. Marlize came over to assist the team and told Barry that he needed to get into DeVoe’s (Neil Sandilands) consciousness. Barry entered through Cecile’s abilities and was able to find Ralph (Hartley Sawyer) alive.
Barry realizes that DeVoe is only keeping Ralph alive because he needs him to keep control. After defeating hundreds of DeVoe clones, Ralph and Barry finally escape the mindscape and ultimately defeat DeVoe as Ralph gets his body back.
However, DeVoe’s chair began to work again and a hologram image of The Thinker appeared. He told Marlize he had planned for this to happen before she unplugged his chair, killing him for good. DeVoe’s death saw the satellite make a fall to Earth. Barry raced to stop the falling shrapnel from killing citizens but as he attempted to destroy the final piece, he got help from a mystery speedster.
That speedster turned out to be Nora. She went into the past because she made a major mistake and needs her family to help her. The question is what did she do and how can Barry and Team Flash help her?
We’ll have to wait for Season 5 for those answers.
The Flash airs on The CW in the U.S. and returns for Season 5 in the fall.
