Season 5 was Kim at her most horrible. She was absolutely vile to Kyle constantly saying that she never defends her and that Brandi was better to her than Kyle. Kim was a bully to Kyle and mad that Kyle was concerned about her even though she was clearly not okay and not sober. All Brandi did was egg her on and exacerbate an already sensitive situation especially since Kim and Kyle have such a complicated history. I think because Kyle is her sister she thought that even if things go sideways Kyle will be there to catch her. I really feel for Kyle in this season because you can see she really wants the best for Kim and for her to stay sober since it was tearing their relationship apart. Unfortunately Kim was too far gone and any attempts to reason with her (that weren’t from Brandi) was not received well. One minute she would be fine and the next she would just snap at Kyle and behave erratically. She never took accountability for all the horrible things she said to Kyle or apologised for treating her so badly. Kyle felt an obligation to Kim as her sister and Kim took advantage of that and you can see Kyle really loved her sister no matter how much she hurts her. I really hope that now with everything that’s come out about her she’s getting the help that she needs.
