Mary: Are you looking for something?

Carson: Lady Mary? I just wanted to make sure the room had been tidied up after the...after the people had left.

Mary: Life can be terribly unfair, can't it?

Carson: It certainly can.

Mary: Everything seems so golden one minute, then turns to ashes the next. Can I ask you a question, Carson? Have you ever felt your life was somehow slipping away and there was nothing you could do to stop it?

Carson: I think everyone feels that at one time or another.

Mary: The odd thing is I feel, for the first time, really, I understand what it is to be happy. It's just I know that I won't be.

Carson: Oh, don't say that, My Lady. Don't raise the white flag quite yet. You'll still be mistress of Downton. Old Lady Grantham hasn't given up the fight, not by a long chalk.

Mary: Oh, that...I wasn't even thinking about that.

Carson: And if I may say so, My Lady, you're still very young.

Mary: Am I? I don't feel it.

Carson: We're all behind you, My Lady. The staff. We're all on your side.

Mary: Thank you, Carson. You've always been so kind to me. Always. From when I was quite a little girl. Why is that?

Carson: Even a butler has his favourites, My Lady.

Mary: Does he? I'm glad.

Anna: Lady Mary. Oh, My Lady, I thought...

Mary: Carson and I were just making sure that everything was ship-shape and Bristol fashion. And it is.
