Once Upon a Time, Season 1

Archie:
I'm gonna continue to treat Henry, and I'm gonna do it my own way.

Regina:
My relief at his safety hasn't changed a thing, Dr. Hopper. You will do as I say, or you...

Archie:
Or what? You'll ruin my life? You'll do your worst? Because I will always do my best.

Regina:
Don't test me.

Archie:
Oh, I don't need to: because you're gonna leave me alone and let me do my work, in peace.

Regina:
Really? Why is that?

Archie:
Because someday, Madam Mayor, you may find yourself in a custody battle. And do you know how the court determines who is a fit parent? They consult an expert. Particularly one, who has treated the child. So, I suggest that you think about that, and you allow me to do my work. And let me do it the way my conscience tells me to.
