[The Doctor takes in a sharp breath - he hadn't realized she had a daughter before. He responds slowly, gently.] Again, Sarah, there is no easy answer. There never is. That's life. You make the best you can of it, and do what you can for the people you love.

[His voice grows harder, more certain and determined.] As to who's to say they won't strip you to nothing? I am. I won't let it happen.

Neither you nor your daughter are property. If they try to take her away, we'll stop them. I'll bring them down so they can never bother you again. Or if you wanted, you and your daughter could come away with me, and leave them all in the dust. I could bring you anywhere in the universe.

[He unconsciously straightens his bowtie.] You'll get the opportunity you should have had to be the mother you want to be. I promise you that.
