The Doctor couldn't help it; he flinched when the young woman joked about a trail of destruction left in his footsteps. How could she have known that, quite literally, that was what he had done with his life? Oh, not on purpose. Never that, but he could see quite clearly, in these borrowed days of a life that was supposed to have ended some weeks ago, what had become of him. That final gunshot fired by Adelaide Brooke still echoed in his memory, and the Master shouting as he threw himself between Rassilon and the Doctor in the final moments of the Time Lords.
"Not as well as I might like," he finally said, when she had asked him about his mood. "It's ... not really something I talk about."
