I remember skipping over reading this when you first posted it, because I had trouble separating this Jack and Clare from Heroes-hiatus-fic!Jack and Clare. I'm well over that now though, and am thoroughly enjoying the ride.

Just one nitpick, though:

"Goodnight, Ellis," Gregory said, the sparks flying from the end of his cigarette as he scraped it out against the house's stonework. Should it be "Goodnight Ellis," Anderson said? He's been Anderson rather than Gregory in the narration so far.
