Who was your Favorite Doctor and companion?
Mine was the 4th Doctor Tom Baker and Leela.
I wish Leela lasted longer in the older episodes though. She wasn't in the many.

For me, it's a tie between 4th Doctor / Romana 1 & 5th Doctor / Nyssa. Romana 1 was such a perfect spoil for the 4th Doctor. They got on like the proverbial house on fire. I only wish their companionship had come under the Philip Hinchcliffe era instead of Graham Williams. And the 5th Doctor / Nyssa pairing was so subtle and quiet - 2 inquisitive minds sharing the adventure and discoveries together. I wish the writers had given Nyssa more to do.
