I just watched Caretaker for the first time in many years.
Here's something I didn't quite understand. It is made pretty clear that the underground Ocampa society is locked off from the surface. Yet how did Neelix meet Kes? Was it after she had already snuck to the surface? I don't think they make this clear - and if so, she was in the possession of the Kazon-Ogla, and probably not for very long. When would they have had time to start their relationship? Was this ever discussed in any tie-in fiction? If anyone knows, I'd be curious to find out.
