The Flash, Season 5

The Flash:
I know how much you care about Grace. You're trying to make the world a better place for her. She didn't choose to be a meta, but she is. Does that mean she deserves to die?

Dwyer:
No, I would never hurt Grace.

The Flash:
Then you'd let her grow up in a world of fear, where there's someone out there, hurting people like her? The cure, it will heal Grace. And you.

Dwyer:
And why should I believe you, Flash?

[The Flash unmasks, revealing Barry Allen's face.]

Barry:
Because I'm a father, too. My daughter, I love her more than I ever thought possible. I would do anything to make the world a better place for her. And I think you would, too. So do it.
