"I think you could command without being patient or diplomatic necessary"
You absolutely can, it's called a ruthless dictator. :-)

I can see Kara being a Peggy's CO but I don't think she would be very good at it or happy at that position. But I like your point, that she would likely change and adapt to the new lifestyle so I could have been pleasantly surprised.

I agree with you about the tough choices too. Kara can definitely make them and she seems on the surface to be much better than Lee in dealing with them (like Olympic Carrier or Cain's assassination) but I just have that feeling that subconsciously they are affecting her much more and that she is much less herself in this kind of situation when the fate of humanity depends on her decisions rather than her viper skills.
