Question: Did the actress who plays Nina know the entire time that she was supposed to be bad, or was this written into the show mid-season?
The End of Time: Part 3 - S1-E40
Question: Why did Gluto decide to freeze himself?
Answer: Gluto has quite a cowardly personality and never contributed too much in fighting against the Power Rangers. When he felt that the final battle was getting too intense for him, he decided that he would rather be frozen than participate.
Chosen answer: Nobody knew, not even the writers, until at least halfway through the season when they were writing the end. They wanted to keep all options open.
