There's never going to be enough Christine fic. This is great. The Stark dynasty's nebulous back story, of course--especially Maria's--, the incomprehensibility and incoherence of a personal history as seen from both inside and outside, the false (or real?) intimacy this creates, but also the deft characterization of Christine--professional, relentless, a little pissed off, a little cruel. She doesn't have any more use for rules than Tony does. Sharp piece of work.
