Hartwell

There are so many ways their relationship can turn by the time BCS catches up to BB's timeline. My gut tells me it'll go one of two ways. One, Kim will disappear altogether. This past episode began to show her character beginning to unravel with Jimmy becoming cold and distant after Chuck's death and the now increasing pressures of her client's (Mesa Verde) aggressive expansion. She will either become insane or disappear. Two, the likeliest theory is she will become Saul's silent partner by the end of BCS. Since they BOTH ran a scam using Ice Station Zebra Associates just to get a cheap high, she'll eventually give in to Jimmy's/Saul's dark side, but only if she remains in anonymity. There are soooo many ways this can play out!

I think Kim expected it to be a scathing goodbye from Chuck along the lines of "you're a no good thief, scumbag, con artist." I believe her blow-up in Howard's office had come back to haunt her more than anything. She also realized by Jimmie's cold reaction to Chuck's letter that she was seeing the end of "James McGill".
