With Penelope's sole purpose of caring for the endangered birds clearly defined, her constancy providing a steady axis for the other to revolve around. A remarkable actor who handle the goofy zoo-girl character with understated quirkiness and dignity at the same time. I would like to have seen more of her and Rufus as returning characters in subsequent episodes. It certainly would have been a nice contrast to all the misfit love affairs to have seen their characters develope. The memorial at the end credits is a sad reminder of her untimely passing as this was Kellie's last appearance on TV. She'll be missed.
