Sorry to hear about Polly though. She was the best of the lot. Like I said, Braun got a bit out there near the end of the series.
One of the best lines in the whole series was with her. She came out with a bit of esoteric information - concerning, I think, the origin of "fib" from "fibble-fabble" - and Qwill said, "With you around, who needs an encyclopedia?" She replied, "Thank you dear. That's the nicest thing you've ever said about me." And coming from Qwill, it was.
