[ Nanoha's rather shocked by the revelation. She always knew it was possible, but she hadn't really encountered an outright villain that had been brought onto Cerealia. ]

Unless Nui actually killed someone on this colony though, I doubt CERES actually cares whether she's a good person or not. [ She's thinking out loud here, trying to figure out what's going on. ]

I won't ask you not to do anything, but there's no way out of the colony, so even if you break her out there's nowhere to go. Besides, there's good reason to believe CERES has trackers embedded into our bodies.
