Logan Roy betrayed his children in Italy: the GOJO deal path sidelined their revolt.
Kendall, Shiv, and Roman tried to block the deal using the vote / board levers and lost.
Tom Wambsgans tipped Logan - Shiv's marriage is a crime scene of loyalty.
Season 3 closed in Tuscany around a wedding that doubled as a boardroom ambush. The siblings believed they had a path to restrain Logan on the GoJo sale. Instead, Logan flipped the board math; Tom's betrayal of Shiv was the intimate knife.
Across Season 3, Kendall swung between messianic whistleblower energy and collapse. Roman became Logan's cruel courtier and punching bag. Shiv tried to be the serious political operator and kept discovering the family does not do meritocracy.
Connor remains the peripheral presidential cosplay and emotional weather vane. Greg Hirsch continues as the upward-failing barnacle - useful, disloyal in small ways, hard to fully fire.
Gerri, Karolina, Frank, Karl, and the old guard survive by reading Logan's mood barometer. The company's public story and private sadism stay braided.
