That is a debate. Some people like to be left on a cliff edge, and other people like to feel they know what happened.

Dramatically, yes, it would have been nice to round it off, but sometimes people over-round things off, so I don't know.

I don't know what they had planned for the fifth season. If Rygel had become dominant and taken over the universe, I think that would have been an appropriate ending.

How do you think Rygel would have developed in the fifth season?

Rygel's character develops in relation to his circumstances, so whatever circumstances came up, he'd have been revealed as being something else. So much was in the hands of the writers and of David Kemper, who was the guiding genius behind it.

Rygel is in many ways the one with the greatest overview, and sees through to the reality of what is happening with all the human beings. Rygel could go anywhere and be great fun to go with.
