It's one of the great mysteries of Succession. No, not "will Roman and Gerri ever consummate their creepy mommy-girlfriend relationship?" but rather "who is the youngest Roy sibling?"
Logan Roy (played by Brian Cox) famously has four children on the HBO hit, and while we know for a fact that Connor (Alan Ruck) is the first-born—remember that "I am the eldest son!" meltdown in the Succession season 3 finale?—and second-son Kendall (Jeremy Strong) was initially Logan's protégé to take over Waystar Royco, there has been some confusion among viewers over the sibling order of his youngest two children: Sarah Snook's Shiv and Kieran Culkin's Roman.
