From Season 1-Episode 2
The servants are discussing Matthew Crawley, Lord Robert's heir, and his mother Isobel
Thomas: So what d'you think we'll make of them?
Sarah O'Brien: I shouldn't think much. *She* hasn't even got a lady's maid.
Anna: It's not a capital offence.
John Bates: She's got a maid - her name's Ellen. She came a day early.
Sarah O'Brien: She's not a lady's maid. She's just a housemaid that fastens hooks and buttons when she has to. There's more to it than that, you know.
Anna: We want some *very* precise reporting when dinner's over.
Thomas: Are we to treat him as the heir?
Sarah O'Brien: Are we heck as like! A doctor's son from Manchester? He'll be lucky if he gets a civil word out of me.
Anna: [drily] We're *all* lucky if we get a civil word out of you.
