It worked for me and I believed it. Not only has she been pushed to the edge in the moment, but also because Howard to her is the worst. He is the opposite of her - a rich kid who became the head a multi-million dollar firm purely through nepotism. No doubt he’s competent. But he’s no Chuck who carried that firm. And no Kim.
Kim who worked her ass off, from neglected child to mail-room clerk, to actual lawyer by being better and more determined than anyone else in the room. All so she could help people, not watch the rich get richer by using her skills to eat everyone else’s lunch.
Meanwhile little rich boy Howard who had everything handed to him on a golden plate pettily retaliated against her by banishing her to paperwork purgatory. Howard backed the idea to snake Mesa Verde from her despite all the work she’d put in. Howard went along with Chuck’s play to ruin Jimmy, a man who had acted unethically but unselfishly to save her position out of love. Howard who had the unmitigated gall to condescend to her and imply she wasn’t in control of her own decisions. As far as she is concerned “nice guy Howard” with his android emotions, his love of money and superior namaste bullshit can fuck right off - he’ll probably still die rich no matter what happens. Meanwhile she gets to actually help people. It’s worth the collateral damage. Because Kim has just about had enough of being the tool of the elites - Jimmy had it right all along.
