The Flash, Season 5

Nora:
[shows Iris the power dampener] Lia found it before she died. You put this inside of me, mom. To dampen my powers? You lied to me my whole life.

Iris:
I know.

Nora:
Who else knows? Who else?

Iris:
Everyone.

Nora:
Everybody? Everyone that I love has been keeping this from me? Why?

Iris:
Because I told them to.

Nora:
Why would you do that?

Iris:
Nora, I was trying to protect you.

Nora:
From what?

Iris:
From this city. From... from meta-humans. From... from yourself.

Nora:
Wow.

Iris:
Nora, you don't understand.

Nora:
No, I don't understand. How did I get my powers? What do you have against speedsters?

Iris:
Nora, I have already lost so much. I can't risk losing you, too.

Nora:
Well, you just did.
