Since i have no idea how to use the spoiler function, i will put it in white text.. lol... (see below)
[spoiler]I do also believe she cares for Jimmy.. However, I think the side that cares for him is the one who enjoys being involved in these wild and crazy ideas he has (like what happened with Huell and the phones.. crazy caper schemes). Being the buttoned up lawyer seems to leave her somewhat dead inside. She clearly has a streak in her that wants to live the "slippin jimmy" style life, hustling, etc.

Also, i'm not sure which incident has affected her to the point of looking completely dead on the outside. Either it was the car accident or it was Chuck's death. It wouldn't seem that Chuck's death would affect her so much, but I think Jimmy's lack of response to it hit her pretty hard for some reason. Just not sure why. Car accident, well, maybe it made her feel like she is putting too much of her focus on corporate/real estate law and it just hollowed her out. The only time this season (so far) we have seen any outburst of emotion from her is after doing the Huell defense, and that was after one of those jimmy-style situations. She is a strange person. Again, I'm REALLLLLY curious to see what happens to her in the near future, because she clearly isn't around during the BB timeline, and it's inching closer to the start of that, so it will be interesting to see why they aren't really together anymore.
