'In The Driver's Seat' is a good episode. The Rangers were tricked by Professor Cog to go to a planet in the RPM universe, while Professor Cog come to the main world. He fought against the Armada, because they didn't like that he was trying to conquer the Earth of their universe. They decide to work together when the Rangers returned from the RPM universe. Professor Cog finally grew big and was finally destroyed. Let's hope that he will never come back.
