Looking for a tentoo/rose oneshot. They were at a bar and he was drunk and regaling all their torchwood friends about their past adventures or something, and she was observing him. After he got done talking to them, she went over, and he started differentiating between himself and 10, saying they were the same man for anything that they did that made rose happy, but weren't whenever it was something bad, like France. I think he forgot the name of the king's mistress, and called 10 a sod/cad.
