That's how these characters operate. That's how these characters have always operated in this show. The show, and the characters, are extremely consistent in this. Nothing matters. Things are always forgotten by these characters if it's convenient for them. I mean, just look at how the siblings act with each other. They say the most heinous shit to each other, stab each other in the back, are genuinely horrible to each other. Not in just a sibling rivalry type of way, but would genuinely feck each other over if it meant they got the top job. And then after all is said and done, they can get in a car ride with one and other, have a genuine heartfelt conversation, hug it out, and Shiv can confide in them about being pregnant.
There's nothing inconsistent or out of the ordinary here.
