I think CJ weighs all options and simply works towards the best one...she's calculated and chances nothing. She works towards the best option and if she's not 100% sure that its the way to go, then she doesn't commit. The fact that no scenario to her is 100% just shows that she's a bit overwhelmed with the scope of things and has no clear direction, it's become complicated. So I think that it makes sense that we hear the conversation that we did with Pegs. Eventually I think this will help her understand that she will have to help Michael more in the pursuit of ending the zombie threat once and for all. Being backed into a corner with the loss of food, water, power, ammo, and whatever else, she will need to come to Michaels side of thinking and go on the offensive. I think that's the whole purpose of the CJ's stuff lately...to make sense of why she needs to and will realise what needs to happen because in the long run, her plan of sustenance will not work.
