I also enjoyed Jason and Erik on the same season, how they transformed from both naive fans into two interesting and colorfull players (eventhough they still stayed naive fans).
Kathy's rise and fall right before the end was one of the most interesting things ever shown.
Kelly W, as OP already mentionned.
Although I didn't really notice/care at the time, the Stephen/JT storyline was interesting as well, in hindsight.
