The Doctor looked at Jack and opened his mouth, but then he closed it again, turning his head to the side and letting him kiss his hand. It was selfish, really, all of this talk. He didn't want Jack to stay with him, but he didn't want to be alone. So much loneliness inherent in him and it was only ever selfishness to drag others into this.

"Back to your problem. Your John." He smiled weakly as he focused his eyes on Jack again. "I'm not sure what to tell you. I know he hurt you and we both know he'll do it again, whether he means to or not."
