The following article contains MAJOR spoilers for Netflix's East of Eden, along with discussions of suicide and sexual assault.
Adapting a titan of American literature like John Steinbeck is no small feat, especially when it's a work that has already been made into a classic movie. However, Zoe Kazan was up to the task, and her interpretation of East of Eden, told as an ambitious seven-episode Netflix miniseries, premiered on October 1, 2026.
Even before its debut, East of Eden garnered controversy for its major departures from its seminal source material and the 1955 film directed by Zoe's grandfather, Elia Kazan. The 2026 series drastically reduced the role of the Hamilton family and gave Cathy, a character written as a wholly evil "psychic monster," a sympathetic backstory. However, Steinbeck's themes of good and evil, the Trasks' Cain and Abel generational curse, and, of course, timshel, are all present in Zoe's Netflix miniseries, particularly in its dramatic final episode.
Cal Dooms Aron When He Chooses Evil Over Good
Every East of Eden character grapples with the perpetual battle of good vs. evil, both in the world and within themselves, and nobody struggles with it more than Caleb "Cal" Trask. Even before Cal sees Cathy for the first time, he knows there's a darkness within him that his father, Adam, and twin brother Aron do not possess.
The twins' biological paternity has been heavily debated, with the Netflix miniseries leaning towards the superfecundation theory, in which Cal and Aron have different fathers — Cal being Charles' son, and Aron being Adam's. This is what Cathy believes to be true, and it explains the emotional distance Adam feels toward Cal.
This, of course, makes Cal desperate for his father's approval, and though he's resentful at being unfavorably compared to Aron, he cares deeply about his twin brother and protecting his pure heart at all costs. As a boy, Cal learns the truth about his mother after overhearing Adam and Lee argue about it. Cal carries the burden of the secret alone so that Aron can continue to believe Cathy is dead.
There's nothing bad about these desires — for Adam's pride and Aron's innocence — but it's the way that Cal goes about serving them, particularly the former, that shows his darkness. Wanting to earn enough money to make his father rich again and send Aron to college, Cal goes into business with the shrewd Will Hamilton, who anticipates a food shortage because of the war and buys up massive amounts of bean crops at peacetime prices.
Cal doesn't once stop to think that this is blatant war profiteering; all he sees is achieving his dream. Alas, when Cal meets his goal of earning $15,000 and hands Adam the gift-wrapped stack of cash, his father is horrified. Just like Cyrus's cold reaction to his birthday present from Charles, Adam doesn't once stop to think about the motivation behind the gift; he just sees the evil in it and in Cal, and refuses it.
With one dream irretrievably shattered, Cal loses all hope and decides to destroy the other, leaning fully into his darkness. Out of implacable spite, he takes Aron to Cathy's brothel, where his innocent twin instantly recognizes his mother. When she confirms the truth of her identity, Aron too is broken.

Squid Game shattered records on launch in 2021, becoming Netflix’s biggest-ever series debut. Hwang Dong-hyuk’s South Korean thriller centres on a desperate gambler named Seong Gi-hun. What is his player number?
✓ Correct! Gi-hun is Player 456 — the last number drawn. Kang Sae-byeok (the North Korean defector) is 067, Cho Sang-woo (the Stanford-educated finance crook) is 218, and the mysterious elderly Oh Il-nam is 001. Squid Game became Netflix’s first show to hit #1 in every country it launched in, amassing over 1.6 billion hours watched in its first month alone.
✗ Eliminated! The answer is 456. Gi-hun’s number is the very last of the 456 players. 067 is Sae-byeok the defector, 218 is Sang-woo the Stanford grad, and 001 is the mysterious old man Oh Il-nam whose identity becomes the series’ biggest reveal. Squid Game became Netflix’s most-watched launch ever, hitting #1 in 94 countries.
02
The Tim Burton-directed Addams Family spin-off set at Nevermore Academy became Netflix’s second-biggest English-language debut in 2022 and launched a TikTok dance craze. Which young actress plays the deadpan title character?
✓ Correct! Jenna Ortega — a Disney Channel graduate and indie-horror favourite (X, Scream VI) — took the role Christina Ricci made iconic in the 1990s films and made it entirely her own. Her now-famous cello-accompanied dance scene became an overnight TikTok phenomenon, and her performance earned Wednesday two Emmy nominations despite airing mid-season.
✗ Eliminated! The answer is Jenna Ortega. Millie Bobby Brown is Eleven on Stranger Things, Sadie Sink plays Max Mayfield (also Stranger Things), and Maya Hawke plays Robin. Ortega’s deadpan Wednesday Addams — and her viral cello-dance scene — turned the show into a global phenomenon in late 2022.
03
In 2013, Netflix released a dark political thriller starring Kevin Spacey as a ruthless congressman breaking the fourth wall. It became the first major streaming original to land a Primetime Emmy nomination and effectively invented prestige streaming TV. Which show was it?
✓ Correct! House of Cards — adapted by Beau Willimon from the 1990 BBC series — became Netflix’s first prestige original and proved a streaming service could go toe-to-toe with HBO. Kevin Spacey’s Frank Underwood and his asides to camera defined early streaming TV. Orange Is the New Black followed months later in July 2013 and became Netflix’s longest-running original at the time.
✗ Eliminated! The answer is House of Cards (February 2013). Orange Is the New Black launched five months later (July 2013), Arrested Development’s Netflix revival came in May 2013, and Hemlock Grove was a horror effort the same spring. House of Cards was the flagship — the first streaming original to earn a Primetime Emmy nomination for Outstanding Drama Series.

Peter Morgan’s The Crown famously recast its entire ensemble every two seasons to age the royal family. After Claire Foy played Queen Elizabeth II in seasons 1-2, which Oscar-winning actress took the crown for seasons 3-4?
✓ Correct! Olivia Colman — fresh off her Best Actress Oscar for The Favourite — played the Queen across seasons 3 and 4, covering the late 1960s through the early Thatcher years. Imelda Staunton took over for seasons 5-6, Helena Bonham Carter played Princess Margaret in seasons 3-4, and Gillian Anderson stole the show as Margaret Thatcher in season 4.
✗ Eliminated! The answer is Olivia Colman. Imelda Staunton took over for the final two seasons (5-6). Helena Bonham Carter played the chain-smoking Princess Margaret during seasons 3-4 alongside Colman. Gillian Anderson delivered an Emmy-winning Margaret Thatcher in season 4. Colman anchored the show’s middle era fresh off her 2019 Oscar win.
05
The Duffer Brothers’ 1980s nostalgia juggernaut sees Eleven and the gang battle inter-dimensional horrors from a portal beneath the town’s Hawkins National Laboratory. In which fictional US town and state is the series set?
✓ Correct! Hawkins, Indiana — a fictional Midwestern small town that became one of TV’s most iconic settings. The Duffer Brothers chose Indiana for its unassuming, ordinary-America vibe, making the supernatural chaos feel more jarring. Derry is Stephen King’s It setting, Hill Valley is from Back to the Future, and Twin Peaks is David Lynch’s famous town.
✗ Eliminated! The answer is Hawkins, Indiana. Derry, Maine is the fictional town from Stephen King’s It. Hill Valley is Marty McFly’s home in Back to the Future. Twin Peaks, Washington is David Lynch’s famous fictional town. Hawkins is The Duffer Brothers’ deliberately ordinary Midwestern setting — the flat, unassuming backdrop that makes Vecna’s horrors hit harder.
06
Netflix’s Regency romance juggernaut — based on Julia Quinn’s novels and famous for its colour-blind casting, string-quartet pop covers, and narrated gossip column — is produced by which prolific showrunner’s production banner?
✓ Correct! Shonda Rhimes — the creator of Grey’s Anatomy and Scandal — produces Bridgerton through her Shondaland banner as the first major fruit of her massive 2017 Netflix deal. Chris Van Dusen created the show, but Shondaland’s signature ensemble-romance DNA is all over it. Julian Fellowes did Downton Abbey, Ryan Murphy did Monster/Dahmer, and Jenji Kohan did Orange Is the New Black.
✗ Eliminated! The answer is Shonda Rhimes (Shondaland). Ryan Murphy produces true-crime anthologies like Monster: The Jeffrey Dahmer Story. Julian Fellowes is the Downton Abbey/Gilded Age creator — a different period drama entirely. Jenji Kohan is behind Orange Is the New Black and Weeds. Bridgerton was the first big payoff of Rhimes’ nine-figure Netflix deal.
07
La Casa de Papel (Money Heist) became a global phenomenon on Netflix after a modest Spanish TV debut — partly thanks to its gang’s instantly recognisable red jumpsuits paired with a mask of which famous figure?
✓ Correct! The Salvador Dalí mask — with its upturned moustache — became the show’s defining visual alongside the red jumpsuits, a nod to Spanish artistic rebellion and surrealist individuality. It inspired protest iconography worldwide, from Lebanon to France. The original Antena 3 version underperformed; Netflix acquired it in 2017, re-edited it, and turned it into a global sensation.
✗ Eliminated! The answer is Salvador Dalí. Guy Fawkes is the V for Vendetta mask that Anonymous adopted. Che Guevara is a common revolutionary image but not the heist crew’s mask. Picasso is a frequent wrong answer given he’s the more globally-known Spanish artist — but the Dalí mask, with its iconic moustache, is the one fused forever with Money Heist’s red jumpsuits.
08
Netflix’s 2020 limited series about a Cold War-era chess prodigy named Beth Harmon caused a global surge in chess-set sales and was one of the streamer’s most-watched shows that year. Who played Beth?
✓ Correct! Anya Taylor-Joy — already a cult favourite from The Witch and Emma — broke out globally as Beth Harmon, winning the Golden Globe for Best Actress. The Queen’s Gambit pulled 62 million households in its first 28 days and caused such a chess-boom that Chess.com and retailers ran out of sets. It also made Walter Tevis’s 1983 novel a surprise bestseller almost 40 years later.
✗ Eliminated! The answer is Anya Taylor-Joy. Florence Pugh (Midsommar, Oppenheimer), Saoirse Ronan (Lady Bird), and Daisy Edgar-Jones (Normal People, Where the Crawdads Sing) are all frequent competitors in similar roles. Taylor-Joy’s Beth Harmon earned her a Golden Globe, a SAG Award, and turned Walter Tevis’s 1983 novel into a sudden bestseller.

Platinum subscriber — or still on the free trial?
He runs off into the night and immediately enlists in the war, wanting to completely distance himself from his family, just as Adam did when he reenlisted in the cavalry rather than return to Cyrus. It's another cycle of the Trasks' generational, Cain-and-Abel-esque curse — only Aron isn't as fortunate as Adam, and dies overseas. Just like Cain murdered Abel in the Bible, Cal indirectly kills Aron by driving him into harm's way.
Florence Pugh's Cathy Ames Experiences The Same Fate As Her Book Counterpart
Though Cathy succeeds in her goal of making herself a rich and independent woman, it comes at a tremendous cost. In East of Eden's final episode, she is physically and mentally broken down, haunted by all the people she hurt and finding comfort only in her imaginary conversations with Charles, the only person who ever understood her.
Cathy may have been rattled when Cal first let himself be known to her, but, having instantly sensed his darkness, he confirmed her belief that all humans are inherently evil. Meeting Aron, on the other hand, irrevocably destroys this worldview. Not only that, but Cathy realizes that she just did the same to him.
Unable to live with what she's done, Cathy takes her own life by ingesting a bottle of morphine. This is in keeping with her Alice in Wonderland obsession, specifically Alice's "Drink Me" potion, which shrinks the heroine down to a minuscule size. Cathy long fantasized about the idea of escaping cruel adults by being able to shrink herself or disappear altogether, and to her, death is the ultimate disappearing act.
This is all in keeping with the Steinbeck novel, but the miniseries shows its departure by recalling how Cathy got to be the way she is in the first place. Despite even her hallucination of Charles abandoning her, she still speaks to him, telling him about what happened to her when she was five years old. Though she can't bring herself to share the truth, the series flashes back to Cathy as a five-year-old in the forest, following the man who would molest her.
After drinking the morphine, Cathy has a final vision of her five-year-old self emerging from the chimney. This young Cathy is happy and sweet and, most importantly, good. Young Cathy skips over to her adult self, and they embrace before taking each other's face in their hands. In her very last moment alive, Cathy realizes that she once had goodness in her and is able to see what that looks like.
It's still a tragic moment, as is her futile gesture of leaving her entire fortune to Aron — which, given Cathy's humanization in this East of Eden adaptation, can be seen as a last-ditch attempt at righting her wrongs. However, this tender final image of Cathy alive is the ultimate bold defiance against the book's stance that she is evil incarnate.
Adam Breaks The Trasks' Generational Curse When He Blesses Cal With Timshel
When the news of Aron's death arrives, it rocks the Trask family to their core. Adam suffers a second stroke, his first occurring after Aron enlisted in the war, and is on his deathbed, while Cal is nearly cursed with the mark of his guilt — his mark of Cain. He goes to his father in Adam's last moments while Lee implores Adam to forgive his only son.
East of Eden's final episode is called "Timshel", in reference to a pivotal conversation between Lee, Sam Hamilton, and Adam. In it, Lee discusses how the King James and American Standard Bibles have a huge contradiction in their translations of Genesis 4:7. In the former, God tells Cain, "thou shalt" rule over sin, whereas the latter says, "do thou," a direct order. However, Lee tracked down the original Hebrew word, "timshel". It means "thou mayest," meaning that Cain, and everyone, always has the power to choose good over evil, but the choice is theirs.
All throughout Cal's life, Adam has rejected him, just as God rejected Cain in the Bible. After having been dealt the blow that Cal's malicious actions are what led to Aron's death, it would have been perfectly in keeping with Adam's character to continue the Trasks' line of paternal rejection, just as Cyrus did with Charles. However, Adam picks a different path, and utters his final word: "Timshel."
Question 1 of 3
By blessing Cal with timshel, Adam is telling his son, "thou mayest" be free from the evil in his bloodline and from the sins of his past and choose the path of good, if that is what he wants. It also means that one bad act does not mark him forever and that timshel is always available to him. East of Eden already showed that Cal wanted a good life with Abra, a woman who not only accepted his flaws but loved him for them. Cal no longer has to worry about his dark side because he has the innately human agency and power to overcome it.
