"Everyone you named aside from Rose was in their own way a pleasant diversion. I did not mind in the least helping them or their families. I could almost have liked the Ponds, actually." And there might have been a slight flicker in her otherwise mask cool expression at Clara's name. "But how exactly do you think to make Rose leave me alone, Doctor? Every other face of yours that tried has failed. And if she has memories as I do of the living city she will, in some ways, have the power to be even more annoying than you."

She considered and then her lip twitched ever so slightly. "Then how about a compromise? If she does show up, and you fail to stop her from going after me, then you allow me to send my raven to her. No attempts to stop me, no attempts to take the timer even if she is selfish enough to offer it. All in, Doctor. Would you bet her life that you can control Rose Tyler?" Line in the sand. Seriously, he has no idea what Rose put her through. What it felt like to have been finally invited to live in the Tardis and then to know she could not stay. Or that moment when Chat Noir declared his side by insisting she go by the name of Ashildr. Rose was a virus. She spread like a plague and there was nothing at all that the patch could do to cure Me of her.
