Once Upon a Time, Season 1

Mary Margaret:
Oh, I thought you had left.

Emma:
Mary Margaret...

Mary Margaret:
But I couldn't tell for sure, because you didn't bother to say goodbye. Do you remember when I left? When I ran, what you said to me? You said we have to stick together. We're like family.

Emma:
Yeah. I'm sorry, I shouldn't have left.

Mary Margaret:
You're right, you shouldn't have. So why, after everything, did you just go?

Emma:
I don't want to be sheriff. I don't want people relying on me. I don't want this, any of it.

Mary Margaret:
What about Henry?

Emma:
I took him with me.

Mary Margaret:
You abducted him?

Emma:
Maybe.

Mary Margaret:
So you don't want people to rely on you, but you took your son? Now that sounds like a stable home for him. What the hell is wrong with you?

Emma:
I want what's best for him!

Mary Margaret:
And running is what's best for him, or is that what's best for you? You're reverting, Emma. Into the person you were before you got here, and I thought you had changed.

Emma:
You thought wrong.

Mary Margaret:
Well regardless, you have to do what's right for Henry now.

Emma:
What's that?

Mary Margaret:
Oh, I don't know. You're his mother. That's your job, so you figure it out.
