It's so hard to say differentiate right now - what' is Jimmy's authentic "real" emotion or thought process or what's part of some long con. I love that aspect of it, cause it makes certain things impossible to try to predict. But it's also part of what Kim's apprehension is based on. She doesn't know for sure what Jimmy's end game is going to really be going forward. Part of that uncertainty is that Jimmy doesn't know dam himself half the time.
I love how they shoot him contemplating/2nd guessing certain decisions, in real time. He considers doing the right thing and following Kim's wishes only to not be able to help himself and ends up going threw with it anyway (or at least to some degree). Same thing with Lalo Salamanca...he sees the family of the victim in the court room, camera sits on him thinking it over, but ultimately snaps back into Saul Goodman and finishes the sell job.
As Kim said though, now with all that's transpired, how will she ever really know if she's part of the con or actually the uninformed mark/target of the scheme (like she was in the Mesa Verde situation)?
Just great TV, imo...i actually find myself anticipating the tension in certain scenes and pausing it just to get myself ready to watch the intensity that's to come!
