Day 213: The Dominators Episode 4

Already, we're able to clearly see the dynamic that has formed between the Doctor, Jamie and Zoe. Jamie acts as the action hero, going off and fighting the monsters, while the Doctor talks with the bad guys to try and figure out their plan using his wits, and then he and Zoe come up with solutions in which to solve this problem. The idea of having a smarter companion for the Doctor has probably been inspired by Anne Travers, the wonderful scientist in The Web of Fear, who was able to show that audiences are able to take two clever people discussing their work, and so they don't require a 'stupid' character to explain what's going on. Meanwhile, the action based role clearly works for Jamie, as he has already had his character built up in that way, ever since The Macra Terror. By playing to the strengths of the various members of the TARDIS crew, and pairing them off together, we are able to truly appreciate the wonderful dynamic that has been built up between the main cast, and despite the fact that it's only their second story together, we already get a strong sense that they've been travelling together for years.
