Questions: How much of Hive's goal is clear here? Why were they testing on 3 and Nick?

HiveMind wants to strengthen their hold on their monopoly, and use anything to their advantage in relation to dark energy. Experimenting on Nick (#4) was a two-fold strategy. Shake Nick's mind for secrets regarding dark energy and turn him into something more useful, and take a stab at the Louvre for attempting to interfere in their affairs. #3 was a failed experiment regarding dark energy, which is why HiveMind care very little if she lives or not.

All of your ideas sound great and on point! If you want her to be a biologist hired by HiveMind and 'resign' after seeing what happened to Nick, that would be an excellent way to start. You would also know the location of where Director Von Galloes set up the trap for the group, and could join them as they decend deeper into the sealed off portion.

[b]Edit:[/b] Going with Voidlight is also a good option that should seriously be considered. I would love to see more Voidlight influence in the story.
