Two years have passed since Season 2 ended, and the alliances and schemes were as layered as an insult from Roman Roy. Here’s a quick catch-up guide.Because of the pandemic, the HBO drama “Succession” has been on hiatus for two years. People who had never seen “Succession” when it racked up seven Emmys last year had plenty of time to catch up ahead of Season 3, which premieres on Sunday. But fans who haven’t seen an episode since the Season 2 finale aired — back in October 2019! — could maybe use a refresher.In that finale, the emotionally unstable corporate stooge Kendall Roy (Jeremy Strong) detonated a bomb under his family’s media empire, delivering damning evidence of a criminal cover-up at a news conference where he was supposed take the blame. It was an unforgettable cliffhanger, capping an eventful Season 2.Here’s a quick overview of what this show’s major characters and companies were up to before Kendall knocked everything askew.From left, Sarah Snook, Strong and Brian Cox in the Season 2 finale. Who will be the sacrificial lamb?Graeme Hunter/HBOWaystar RoycoThe show’s primary setting — and its main plot driver — is the media conglomerate Waystar Royco, a powerful corporation known primarily for its Fox-style conservative cable news channel, ATN. (The similarities to Rupert Murdoch’s News Corporation are, to put it mildly, intentional.) The company is also active in online media, publishing, entertainment, theme parks and cruise ships. Through the first two seasons, Waystar has been under attack from politicians and business rivals, and has been the target of multiple attempts at both negotiated mergers and hostile takeovers.In Season 2, news leaked that top Waystar executives had buried internal reports about a longtime associate in the company cruise line: Lester McClintock, nicknamed “Uncle Moe” (as in “moe-lester”). McClintock, now dead, had a history of sexual harassment and assault — and possibly murder. The scandal has led to embarrassing media investigations and congressional hearings. It’s what ultimately prompted Kendall to betray his father, Logan.Brian Cox as Logan Roy, in one of his quieter moments.Graeme Hunter/HBOLogan RoyIn the series’s first episode, Waystar’s irascible, monolithic, octogenarian founder, Logan Roy (Brian Cox), was felled by a stroke. The timing wasn’t great: He had just been about to announce a plan of succession, which would have seen him stick around as his company’s chief executive while his third wife, Marcia (Hiam Abbass), would have the power to name his eventual successor. The medical crisis set off a scramble, dividing the Roy children and Waystar’s inner circle of advisers.Logan recovered … sort of. (He has had multiple public moments of unprovoked fury and foggy memories since the stroke.) By the start of Season 2, he had called in enough favors and played enough on his family’s sympathies to bring most of his loved ones and his associates back together — although Kendall’s power-play in the Season 2 finale proved how tenuous that truce actually was.A complicated and volatile man, Logan had a childhood in Scotland marred by want and abuse. His relationship with his children and his underlings has been pretty raw at times, with Logan defaulting almost by habit to psychological manipulation and fits of rage. His capriciousness has tested his marriage to Marcia, who toward the end of last season grew frustrated by her husband’s rumored affair with Rhea Jarrell (Holly Hunter), a rival media magnate he tried — and failed — to sway into running Waystar.Strong with Nicholas Braun, who plays Cousin Greg, in a scene from the coming season.David M. Russell/HBOKendall and GregOne of the few members of the Roy family who seem genuinely excited by corporate jargon and robber baron blindsides, the longtime Logan loyalist Kendall rebelled in Season 1 after realizing that his father had no intention of naming him as next in line. He then orchestrated a plan to steal the company from his father before a relapse into substance abuse — culminating in a tragic car accident at his sister’s wedding — led a newly contrite Kendall back into the fold.In Season 2, Kendall settled into a role as Logan’s shameless hatchet-man, willing to humiliate himself and to eviscerate the undeserving to promote Waystar’s interests. But his dad’s demand that Kendall take the fall for the cruise ship scandal went a step too far, prompting him to pull the big switcheroo in the season finale’s climactic news conference.Kendall’s unlikely accomplice in that ambush is his cousin Greg Hirsch (Nicholas Braun), the grandson of Logan’s disapproving brother Ewan (James Cromwell). The gawky, bumbling Greg is a frequent target of the Roy family’s jokes and bullying — a fate that he accepts as a trade-off for access to their money, power and drugs. In Season 1, he smartly held onto some damning documents about Brightstar’s troubles, anticipating the moment when he could use them as leverage.That moment arrives after the family openly considers adding some “Greg sprinkles” to whomever they serve up on a platter to take the fall for the cruise fiasco. And after Kendall finds himself in need of a plan.Matthew Macfadyen and Sarah Snook as Tom and Shiv, whose marriage is … very complicated.Zach Dilgard/HBOSiobhan and TomIt’s hard to say who in the Roy family has been most hurt by Kendall and Greg’s betrayal, but the situation is pretty dire for Tom Wambsgans (Matthew Macfadyen), the husband to Logan’s daughter, Siobhan (usually called Shiv, played by Sarah Snook). A former executive in Waystar’s parks and cruises division — and Greg’s immediate superior — Tom not only knew about Uncle Moe’s crimes but also helped in the cover-up.At the end of Season 1, Tom learned — on the day of his wedding, no less — that his then-fiancée, Shiv, wanted to have an open relationship. He suffered through that arrangement for most of Season 2 before finally admitting his unhappiness in the finale. A major part of Tom’s frustration has to do with his taking a thankless position at ATN in hopes of setting himself up for more responsibility down the line … only to find that Logan had secretly named Shiv as the big Waystar successor.As for Shiv, she quickly learned last season that her dad’s promise to let her take over was a ploy to keep his left-leaning feminist daughter under his control rather than allow her to cozy up to political enemies. As soon as Logan saw the potential advantage in setting up Rhea as the next in line, he let Shiv dangle. Ever since, his daughter has been staying publicly faithful while working behind the scenes to sabotage her rivals and get back onto Logan’s radar as a future Waystar boss.Roman and Gerri (Kieran Culkin and J. Smith-Cameron): also complicated.Peter Kramer/HBORoman and GerriThe Roy family’s unexpected Season 2 all-star was Logan’s youngest son, Roman (Kieran Culkin), a notorious cynic and an unapologetic slacker, who suddenly set out to prove to his father that he could make smart deals on Waystar’s behalf. While Kendall has wanted to lead the company into a new era and to protect his dad’s legacy, and while Shiv has wanted to distance Waystar from its toxic reputation, the incorrigible troll Roman relishes the idea of running a powerful organization that annoys a lot of people.Roman surprises even Logan by securing enough foreign money to take Waystar private — before advising his father to reject the deal and to try working with someone closer to the family’s political interests. For his industriousness, Roman is named Waystar’s sole chief operating officer (a position he previously shared with Kendall) in the Season 2 finale.Throughout this shift toward ambition and guile, Roman has been quietly assisted by Gerri Kellman (J. Smith-Cameron), a longtime Waystar lawyer who has worried often that her boss might throw her to the wolves to save himself. As she has whispered ideas in Roman’s ear, the two have developed a freaky quasi-sexual relationship, in which Gerri turns him on by playing the demanding mommy figure.Justine Lupe and Alan Ruck as the aspiring playwright Willa and the Roy brother from another mother, Connor.Zach Dilgard/HBOConnor (and company)Kendall, Shiv and Roman are Logan’s children from his second wife; but the siblings also have an older half brother, Connor (Alan Ruck). Connor has never been that active in the family business, opting instead to spend money and promote himself as a libertarian firebrand.In Season 2, these hobbies create headaches for Logan. Connor announces a run for president of the United States, arguing for free market reforms that wouldn’t serve Waystar’s interests. At the same time, he pours much of his fortune into the Broadway dreams of his ex-sex-worker girlfriend, Willa (Justine Lupe), who has written a flop play. Logan handles both of these problems at once, agreeing to cover his son’s showbiz losses in return for his dropping the presidential campaign.Connor is a minor “Succession” character compared to some; but while this show’s cast is huge, the creator Jesse Armstrong has had a long-term narrative use for nearly everyone. A case in point is Stewy Hosseini (Arian Moayed), who was introduced in Season 1 as an old friend of Kendall’s with enough money to help get Waystar out a financial jam; he has since become a pesky enemy, determined to hold onto his stake in the company and to outlast the Roys on the board.Anyone could end up being a power-player in “Succession” Season 3. This is a show where loyalties shift overnight, and no grudge is forgotten. More
