Downton Abbey, Series Three (1920-1921)

Lady Mary Crawley:
I wish you'd come back to the drawing room.

Robert Crawley, Lord Grantham:
I'd only set your mother's teeth on edge.

Lady Mary Crawley:
She'll come through it. She will. Which brings me to your performance today. How did that help?

Robert Crawley, Lord Grantham:
I was angry with Isobel for exposing you all to gossip.

Lady Mary Crawley:
You were angry all right, but not with Isobel or Ethel. I think it's because the world isn't going you way. Not anymore.

...

Lady Mary Crawley:
You won't win over the christening.

Robert Crawley, Lord Grantham:
Not if you're against me.

Lady Mary Crawley:
I'm never against you. But you've lost on this one.

Robert Crawley, Lord Grantham:
Did Sybil truly not mind?

Lady Mary Crawley:
She wanted Tom to be happy. She loved him very much, you know. We all need to remember that.

Robert Crawley, Lord Grantham:
I keep forgetting she's gone. I see things in the paper that would make her laugh. I come inside to tell her that her favorite rose is in bloom, and then suddenly...

Lady Mary Crawley:
Say that to Mama. Please.

Robert Crawley, Lord Grantham:
She doesn't want to hear it from me.
