Explaining The Twist Ending Of The Flash’s 100th Episode

It’s traditional for The Flash‘s mid-season finales to leave us with a big game-changing twist that’ll mould the shape of the story when the show returns afters its winter break, and season 5’s no different. Due to next week’s episode forming part of the “Elseworlds” crossover, the series’ celebratory 100th episode also doubled up as the mid-season finale, and it left us with a whopper of a cliffhanger.

Of course, we’re talking about the scene where having travelled back through her dad Barry Allen’s personal history in the episode, titled “What’s Past Is Prologue,” Nora West-Allen was revealed to be scanning coded pages from her diary through Gideon in the Time Vault. Clearly, she was up to no good.

We then found out who she was sending them to when she follows up those messages by delivering something else in person. Speeding to the year 2049, Nora visits someone in a cell who she says she needs to speak with: it’s Eobard Thawne AKA Reverse-Flash, once again in his Harrison Wells disguise. Yup, it seems that Nora’s working with her pop’s number one nemesis.

So, what’s she doing allying herself with the villain? Well, the folks at ComicBook.com may have figured it out. It’s worth noting that the date Nora travels to is 2049, which is the same year the newspaper we saw back in the season premiere was from that commemorated the 25th anniversary since the Flash disappeared in a “crisis.” Remember that an extract from that article mentioned that the Reverse-Flash was present during this monumental battle, “leading an army of shadow demons.”

Maybe Nora’s secretly trying to avert her father’s disappearance in the first place and is working with Thawne to make that happen – he could be incredibly useful as he was there. However, she should know that Reverse-Flash can’t be trusted and he’s bound to have his own hidden agenda.

We’ll have to wait a bit longer to get some firm answers, but this was a great way to end the episode and we can’t wait for The Flash to return so we can learn more about what’s really going on here.
