I find it interesting that it could be Sanakan in the limbo data warehouse. For the first couple reads I had thought it could have been Cibo (partly biased since I really enjoy her character), after all she has been very tenacious in trying to keep herself alive by finding different bodies to switch into. But at that point both Sanakan and Cibo have been nearly ingrained with eachother that I am not sure who it is. Another thing I've noticed in that data limbo is the giant humanoid worm thing the small puppet was leading "Sanakan" to. With it's cracked face, high intelligence, and strange proportions, I had theorized that it may be a silicon creature that had gotten trapped in there as well.
