How Antinous Betrayed Sinon in Christopher Nolan’s ‘The Odyssey,’ Explained

Christopher Nolan’s ‘The Odyssey‘ has audiences buzzing about far more than its massive scale and star studded cast. One of the film’s most emotionally devastating threads involves the betrayal between two Ithacan boys, Sinon and Antinous, whose shared history unravels into one of the movie’s biggest gut punches.

Fans have been searching for answers about how this betrayal actually plays out on screen, since the film uses a non linear structure to reveal it in pieces. Nolan tells the story through flashbacks that gradually reveal the complicated history between young contemporaries Sinon, played by Elliot Page, and Antinous, played by Robert Pattinson.

The Lottery That Started It All

The betrayal begins years before the main events of the film, when Ithaca needed soldiers for the Trojan War. Odysseus’ loyal swineherd Eumaeus, played by John Leguizamo, explains to Telemachus that Odysseus used a lottery system to find soldiers to join him in the war.

When a young Antinous pulled the small metal rod that meant he had been chosen to serve, his father arranged for Sinon to end up with that same rod and go to war in his place. This single moment sets the entire tragedy in motion, since Sinon never had a real choice in the matter.

In Nolan’s version, Sinon is the son of a servant who works for the aristocratic family of Antinous, which makes the power imbalance between the two boys even starker. Antinous was born into wealth and status, while Sinon’s family depended on the goodwill of Antinous’ household to survive.

According to Antinous’ own account, he claims he actually begged Odysseus to let him fight, but the king of Ithaca refused and asked him to stay behind to look after his son Telemachus instead. That version paints Antinous as noble, but it directly contradicts what everyone else in Ithaca seems to believe.

Antinous’ Broken Promise to Sinon

The emotional core of the betrayal comes down to a deal that Antinous never honored. Because he was too afraid to fight, Antinous made Sinon an offer, telling him that if he took his place in the war, his father would pay Sinon’s family for the sacrifice.

That promise turned out to be worthless. Antinous manipulated the young Sinon into taking his place, promising to protect Sinon’s father, a promise he never fulfilled, leaving the man to die in poverty following Sinon’s death during the sack of Troy.

The film does not let Antinous off the hook quietly either. When confronted, Antinous insists the payment deal never happened, but his anger in that moment reveals the truth, and he throws the lottery rod back at a disguised Odysseus, who later returns it by forcing it into Antinous’ mouth after stabbing him in the heart.

Sinon spent ten grueling years believing his sacrifice meant something for his family back home, only to eventually be sent to deliver the Trojan Horse to the enemy, a mission where he was deliberately kept in the dark about the real plan so his performance in front of the Trojans would feel convincing.

Sinon’s Sacrifice and the Trojan Horse

Sinon’s role in the war effort makes his betrayal by Antinous even more tragic, since he never stopped being loyal to Ithaca despite everything he lost. Sinon is portrayed as an honorable character who genuinely believes the Trojan Horse is a gift to Athena, with no idea it is actually a trap for the Trojans.

His devotion ultimately costs him his life. When Odysseus’ enemies discovered the Trojan Horse, they believed Sinon was a threat and killed him, though he maintained until his dying breath that the horse was meant as an offering to Athena, played by Zendaya.

Sinon becomes the first character to die on screen in ‘The Odyssey,’ and he delivers a scathing, emotional monologue to Odysseus later on when the king travels to the underworld and speaks with the dead. That confrontation forces Odysseus to reckon with his own role in Sinon’s fate, not just Antinous’ cowardice.

Sinon’s dead soul later tasks Odysseus with returning a totem to Antinous, meant to remind him of his cowardice for the rest of his life. It becomes one of the more haunting threads connecting the war years to the events unfolding back home in Ithaca.

How the Betrayal Resolves by the Film’s End

The consequences of Antinous’ betrayal finally catch up to him during the film’s climax. By the time Antinous realizes Odysseus has returned to Ithaca disguised as a beggar seeking vengeance, he is revealed to be a pathetic coward who would rather bark orders than fight Odysseus head on.

His cruelty toward Sinon fits a broader pattern of casual cowardice and cruelty throughout the film. Antinous shows his true nature by kicking Odysseus’ aging dog Argos when the animal is weakened and dying, leaving it to die outside the castle, and later murdering Eumaeus’ shepherd dogs while stealing his swine.

Antinous ultimately gets the chance to fight Odysseus directly, but instead falls back and orders the other suitors to finish the job for him, proving that the cowardice he showed as a boy avoiding the war never actually went away. The film frames this as poetic justice, since the same fear that led him to sacrifice Sinon in the first place is what dooms him in the end.

Odysseus makes sure Antinous understands exactly why he is dying. Odysseus returns the lottery rod by jamming it into the mouth of the suitor after stabbing Antinous in the heart, telling him to let Sinon know that Odysseus kept his promise. It is a brutal final image that ties Sinon’s long forgotten sacrifice directly to Antinous’ death.

The layered way Nolan reveals this betrayal, through flashbacks, conflicting accounts, and a devastating underworld confrontation, has become one of the most talked about elements of the film’s storytelling. What do you think Sinon would say if he could see how Odysseus finally settled the score with Antinous?
