Barry and Cicada in “Unfinished Business”

Barry

Cicada.

Cicada

Is that what you call me?

Barry

Not all metahumans are responsible for what happened to Grace.

Cicada

Yes, they are. The destruction they cause. The death. The pain.

Barry

I know about pain and death. Taking it out on the world, that's not gonna help. Think about Grace.

Cicada

She's all I think about, Flash. And I'm making the world safe for her. Every metahuman must go.

Barry

And what about you? You're a metahuman now.

Cicada

I am. And after you're gone, I'll join you.
