Once Upon a Time2011

[Mary Margaret tells David about her fateful encounter with Regina]

David Nolan:
Why didn't you tell me?

Mary Margaret Blanchard:
Because telling you makes things real, and I needed to believe it wasn't; that I could find a way to stop it, that redemption was possible.

David Nolan:
It is. Look at August.

Mary Margaret Blanchard:
But it cost him... everything.

David Nolan:
You are not him, Mary Margaret, and you sure as hell aren't Regina. Which means, those are not the only two options. We'll find another way. I know it.

Mary Margaret Blanchard:
What makes you so sure?

[he places her hand over her heart]

David Nolan:
This does. And I know it better than anyone.
