Nicola Walker and Peter Firth

[DogSoSmall]

Nicola really does prove again and again what a lovely person she is. No wonder she has such devoted fans!

[Bourgy]

I disagree with almost everyone on this but I though their chemistry wasn't as epic as many people describe.
I never really liked Ruth. There just didn't seem to be a proper transition of how she moved from shy, couldn't get a man, begging to be in MI5 Ruth, to this force of nature who knew everything.
