Lady Mary: O'Brien told her Bates can't do thejob properly. Why was he taken on ? 

Anna:Oh, he was Lord Grantham's batman when he was fighting the Boers. 

LadyMary: I know that, but even so. 

Anna:I think it's romantic. 

LadyMary: I don't. How can a valet do his work if he's lame? 

Anna:He's not very lame. 

Anna:There. Anything else before I go down? 

LadyMary: No, that's it. Thank you.
