The Flash, Season 5

Cecile:
Hey, we're almost through this. We're gonna get all of these people to safety.

Barry:
Even if we do, Cicada's not gonna stop killing. Not until–

Cecile:
[getting an empathic feeling from Barry] –until he's... dead.

Barry:
... I didn't say that.

Cecile:
You didn't have to. The anger that I feel from you says it all.

Barry:
How am I supposed to feel?! He almost killed Nora.

Cecile:
Barry, I understand. I do. That man hurt your child. But this anger that you're feeling, I have felt it before. From Cicada. Honey, if you let it, this rage will consume you, the same way it's already consumed him.
