But Cain wanting to kill Adama is not so much out of character. I mean she shot Belzen who was not only her XO but her friend... so she wouldnt have too much issues with shooting Bill.
I'm just saying I don't think Cain would have made that decision at that point, I mean: Adama's not really a problem here, he has to obey her command, he's a good officer (so he will as long as it's not killing his own people) and he's a softy (and I'm sure Cain is smart enough to know this kind of things ASAP).
Another reason I don't think she'd ask Fisk to do it at that point is that her more extreme decisions were made in moments she was very angry and/or feeling vulnerable. Remember Belzen defied her when she was trying to pull it together, get the rest of Humanity to a good end and lead everyone making them keep their minds. And then, after Gina made *that* to her... People didn't matter anymore, everyone could make a sacrifice if it was necessary. I don't see Adama as this kind of thread, I don't see his death as something Cain would think to be needed. That's the reason it's out of character for me.
And concerning Roslin: she wouldn't put much effort to create a relationship with her, but she would see she's the way to Adama and once they are trying to live together and run the fleet (Cain would also learn she needs Adama to have Galactica's people favor), some kind of 'good' relationship would have to be established for the shake of both parts.
And yay! For me, Cain and Roslin could make and awesome team if they were able to get to that point together.
