I hope Tom's comment to Shiv about her "hurting him more than she can possibly imagine" is because, in the middle of an argument, she reveals that she was pregnant but she got an abortion
shiv's motivations for voting to pass the gojo deal are so layered and i don't think they should be dismissed in favour of any one interpretation. shiv desperately grabbed on to a lifeline for her relationship with tom. shiv was the deciding vote and she couldn't bear to hold the crown only for a moment just to place it atop her brother's head. shiv knew she would have more influence as wife of CEO rather than sister of CEO. shiv absolutely hated seeing kendall crystallize into logan before her eyes, especially when he made roman bleed ("and if we did kill him we get to go to bed") -- succession has always been about siblings so of course she tried to free her brothers before her child. shiv still thinks she can raise her child with all the material benefits of being the daughter of waystar CEO while doing better by her, whatever that means. and all of those things are true
Shout out to whoever said one of Shiv's visceral, emotional reasons was that Tom would never be able to take the moral high ground in their relationship again. Because exactly!
Shiv still might be fucked in the business sense because Tom is a puppet and Matsson doesn't respect her, but in terms of her marriage... She still wants him even after the worst things have been said, and the "worst thing" he was most upset by was that she repeatedly left him out to dry in pursuit of her own power. Well, now it doesn't matter how valid his complaints were! He can never make that particular point again without the most loaded silence of his life! And on top of that, he's added another betrayal of her. That new imbalance more than anything is what will derail the divorce, and make it so she's NOT meekly coming home and begging him to let her stay as his housewife or whatever.
Business power is still up in the air, but she's taken a huge amount of private power back. It was an emotional move driven more by hurt than logic, but she's still done it!
And I do appreciate the TomGreg parallel here, too, because Greg has always been Tom's solution to feeling like Shiv was above him. His own personal Roy to lord over. Their friction was coming from Greg growing an ego around the Roy name and trying to leverage himself out from under Tom's thumb. Well, now he's fucked it! It's not Royco anymore! Greg doesn't have Matsson's backing, his name is worthless, and he overplayed himself into a certain death situation. And then here's Tom, letting him stay despite the betrayal but only because Tom bought him.
Tom got the crown, Shiv got the marital upper hand to help her deal with that, and Tom got Greg to help him deal with that.
They are so fucking dysfunctional but maybe TomShiv can make this work 😘
