^^ Well she had the voice for it!
Re UPN, no you're right. There likely would have been another series after DS9, or more likely, just before DS9 ended. Whether that would have ended up being Voyager who knows?! Of course, the other factor for concern there is that the syndicated market started to fall apart in terms of first run syndication shows, hence it may not have come about at all with the climate being what it was when DS9 was finishing.
