Ramsay Bolton - The Devil Within

"You will pretend to be a prince," Lord Ramsay told him. "but we know the truth. You're Reek. You'll always be Reek, no matter how sweet you smell... You will be tempted to betray me. To run or fight or join our foes. No, quiet, I'll not hear you deny it. A man would turn against me in your place, but we know what you are, don't we? Betray me if you want, it makes no matter ...but count your fingers first and know the cost....." George RR Martin, A Dance With Dragons
