Downton Abbey, The London Season

Lady Mary Crawley:
So Bates was in London that day.

Mrs. Hughes:
You say it as if you already knew? Does Anna suspect anything?

Lady Mary Crawley:
Of course not. She;s knows nothing.

Mrs. Hughes:
So will you tell her now, Millay?

Lady Mary Crawley:
I gather you won't?

Mrs. Hughes:
No. I'm handing this over to you.

Lady Mary Crawley:
Meaning, leave it alone?

Mrs. Hughes:
We can't know what happened on that street. Maybe he was in London for an innocent reason and nowhere near Piccadilly. But this I will say: If he was there to avenge his wife's honor, I won't condemn him for it. I'm sorry but I won't.
