The Flash season 5 episode 21 is set to arrive this week, with the title "The Girl With The Red Lightning." One of the most interesting things to anticipate in this episode is that it would be Cicada and Team Flash finding ways on how to take her down.
According to the synopsis of The Flash season 5 episode 20, Cicada II is making her move, and Team Flash is now on high alert as she threatens to unleash the dangerous virus - putting all meta-humans at risk. It's clear that she wants to destroy them, but how far can she go to make this happen?
It's also obvious Cicada got a scheme on how to eradicate all meta-humans from the Earth, so what can Team Flash do to take her down? If Barry Allen has a way to stop her, it is something that would evade him in some other timelines. So, what does this mean for the future?
Perhaps, one of the speculations is that Nora will cease to exist due to the changes in the present timelines. Another thing is that Barry and Iris might have twins as they do in the comics, or it is possible Iris could get pregnant earlier than she originally did.
Thus, Cicada's plot in The Flash season 5 episode 21 is crucial at this point since it would affect some of the timelines. But then, they could also stop her from doing her plan of destroying all meta-humans. There is someone who got an idea to protect them by bringing them all in the police headquarter.
However, that isn't a good idea at all. If they gather all people together at one place, they'd all be dead when Cicada infiltrates. So, that's one thing Team Flash needs to figure out in this episode, and instead, they should find ways to halt the anti-cure from getting out before it could be everyone.
But as per CarterMatt, everyone will get through this, yet they could find another threat on Reverse Flash. He remains to be Barry's most iconic nemesis the moment he was brought back this season, so there might be more things to expect on his part. Hence, it would still be a battle speedster vs. speedster, as that's what always in the cards since then.
The Flash season 5 episode 21 will air on Tuesday, May 7, on the CW.
