Stating that their Others must have been certifiable might not have met much, if any, disagreement. Lazarus and Nathan may not be well themselves, but they are probably, in their own way, healthier people than they'd been in that other life.

Or at least better people.

"It is sad." Nathan agrees to that much without hesitation. "Unfortunately, it's unlikely that many of the memories you get will be of good things."

He doesn't want to paint a completely hopeless picture, but the fact is that their old lives were . . . twisted, sad, and dangerous. Perhaps there is some good interspersed with it all, but hardly any of that has been borne out by Echoes. Generally, neutral memories are the best that any of them have a right to hope for.
