Isadora lifted her shoulders in a light shrug. "Observation, I suppose. Kill a couple of rats and see how their cage mates react," she quipped dryly. "They claim they're simply observing us. Apparently their latest trick is sending people away to see how everyone copes with that." She made a slight gesture with one hand before returning it to Iridia's head, stroking gently. "One of the women that is no longer here was something of a ... figure, around here. The sort that everyone knew and most everyone liked. Something like a leader, if we were to claim to have such things. So of course they would take her to see how we functioned in her absence."
Isadora was not at all inclined to mention her thoughts on why they might have taken Spike. It disturbed her more than she wanted to let on that they'd taken him, and that wasn't something she wanted to investigate too deeply.
"Some apparently have. Some outwardly fight it. Others may be biding their time and plotting for an opportunity to escape, or at least turn the tables on our captors." She was in the latter group, but she saw no reason at all to let onto that. Not when she knew (or highly suspected) that this entire conversation was being recorded. That they were watching her, even now.
"The same way the others did, I imagine. We all wake up here. Some people claim to have memories or dreams of people in white coats invading their bedroom. Others I imagine were snatched just before their demise, from the stories I've heard. As for how ..." she splayed her hands in a 'who can say' gesture. "They have methods of technology far beyond my humble grasp."
