oooh, good story. I was reading the comments about being based on a Voyager ep and I honestly had to go look back on the episode you mentioned. The first one that came to mind was from season 7 "Shattered", but then I realized (in great Trek fashion) that they had done the idea before.

A good job with bringing Elizabeth back from the replicators without dwelling too much on the obviously angsty idea of having her back but no longer with it.
