The Flash season 5 episode 21 spoilers: Cicada II plots her endgame

As we reach the end of The Flash season 5, this is the time for questions and deep pondering … including why the show is taking so long to get back to the Cicada storyline. We know that there’s some cool stuff planned for some of the upcoming episodes, but it may not be until episode 21 (entitled “The Girl with the Red Lightning” — which sounds more like a Stieg Larsson book than a title for this show) where we see the Big Bad again. We’re now at a stage where Sarah Carter is playing the baddie, as her version, a.k.a. an adult Grace from the future, is plotting her final plan for meta-humans.

We know that Cicada wants to destroy them … but how far is she willing to go to make that happen? Think so far as to if she gets her way, we may not ever see Nora make it to her point in the timeline. She’s got a scheme where on the other side of it is the eradication of all meta-humans from the Earth. Sure, there’s the strategy where you take your time being a little more methodical … but why not just try to finish the job all at once?

Remember that what makes this version of the character so darn dangerous is that she possesses years worth of training. Our original version of Cicada, Orlin Dwyer, was basically a duct-tape villain who was effective despite doing basically everything on the fly. He had no real training; he was just operating on pure rage. Grace has had years to perfect her training and practices of killing meta-humans. She’s also from the future, a timeline where she may have had a little more technology at her disposal. With some of what she’s learned, she’s coming back to take on people who may not have any sort of adequate defense for her.

For some more news on what’s coming up, check out the official The Flash season 5 episode 21 synopsis:

CICADA II MAKES HER MOVE – Team Flash is on high alert after Cicada II (guest star Sarah Carter) threatens to unleash a dangerous virus that would put all meta-humans at risk. Stefan Pleszczynski directed the episode written by Judalina Neira & Thomas Pound (#521). Original airdate 5/7/2019.

It’s clear that The CW isn’t giving you too much, but we think that it’s pretty clear at this point that there is a lot at stake. There is stopping Cicada, making sure everyone stays alive, and then also figuring out what to do with Nora. While she’s come to fit in this universe in a lot of ways, we don’t know how you can consider this anything other than a temporary stay. She’s always had another home, and she’s got some other people in that world. Real friends. People who understand her, even if that version of Iris doesn’t. We’re also curious to know just how much she can change, if she does, if Barry does make it past Crisis on Infinite Earths and the future timeline does actually change … though that may be a question for another time. Let’s just try to get rid of Cicada II now.

Want to see what’s coming up on next week’s episode?

It’s entitled “Snow Pack” and (big shocker!) it’s all about the return of Caitlin’s father and her doing what she can to reunite with her mother to take him down. It’s both predictable in one way and exciting in another, just because we’re finally getting a chance to focus on it. You can read more about it over at the link here.
