well they better bring Cassie in for the next season.
as for generation 3, I lost interest when they killed off the most rational and realistic character of them all, Grace. now I'm starting to think that it was the reason - she was too realistic and didn't fit it with the rest of the group.
and jeez, Franky was such an interesting character in the very beginning of season 5, what have they done to her? I cringe every time I see her now. SO much potential, all lost.
