Spoilers below for The Flash's Season 4 finale, so be sure to watch before reading on.
After a season full of The Thinker's precognitive mind games giving Barry and his fellow Team Flash members some of their biggest headaches yet, The Flash brought Season 4 to a close in a most dramatic fashion, with the titular hero breaking into Clifford DeVoe's consciousness and saving a former teammate in the process. In the end, some mysteries were solved, while other answers remained just out of reach, and unsurprisingly, quite a few new questions popped up in the interim. So let's break down all the biggest elements going into next season.
What's Up With Nora Allen's Big Mistake?
The Mystery Girl finally got a name! And though she didn't exactly have the name we were expecting, with Dawn being the more comic-specific moniker, Nora Allen's identity as Barry and Iris' speedster daughter was right in line with many predictions made about the character. (And "Nora" also fits in with the "Nora shouldn't be here" line that Barry garbled in the premiere.) But what was the big mistake she referred to making in the future? Here's how showrunner and executive producer Todd Helbing put it to EW.
Many fans probably assumed that there was an innate importance to the specific moments when Mystery Girl showed up to the various Team Flash members, especially when it happened on Barry and Iris' planned wedding day. But how will those play into Nora's time-travel foibles? And is it possible that her mistakes have anything to do with the fate of a potential twin brother, or has the TV show decided to leave the brother out of it? Also, is Wally going to be a cool uncle or what?
Why Did Nora Allen Behave So Strangely Before?
While Nora's first appearance as Mystery Girl pegged her as sweet and possibly sympathetic to Barry Allen, her later appearances didn't always seem quite so kindhearted. Particularly when she spilled coffee on Caitlin. To that end, fans had also been questioning why Iris and Nora hadn't ever shared the screen together. According to Todd Helbing, it's Nora's knowledge of the future that guides her interactions with everyone.
Does that mean Caitlin is going to get her Killer Frost powers back and ruin something for Nora? Or will something else cause strife there? As well, now that we know Nora definitely is wearing the same jacket as her mother, are we meant to believe that Iris gave it to Nora for reasons that imply she isn't around anymore in Nora's present? Did her big mistake cause tragedies within the West-Allen families? It's so easy to picture worst-case scenarios here.
