"I've asked myself that any number of times," Cameron says, looking down the street before them in a slightly unfocused fashion, her mind somewhere else. "I can't get past the impossibility of it to decide what I'd prefer."

The downside of her pursuit of rationality. There are pros and cons to forgetting and remembering alike, anyway, and the question of whether the good memories would outweigh the bad ones is too philosophical for her to sort out one way or another. Decisiveness has never been Cameron's forte. "Besides," she adds, a wry little smile tugging at her lips, "If I woke up at home tomorrow remembering all of this, I'd be forced to come to the conclusion that I'd had some kind of psychotic break." Reality remaining inviolate is an essential prerequisite for the assumption that the City is, in some fashion, real.
