Netflix’s limited series Sirens concludes with intense drama and emotional fallout, particularly surrounding the mysterious disappearance of Ethan Corbin III. The psychological thriller spans five episodes and explores complex relationships among the wealthy elite in Port Haven. The ending leaves many wondering: what truly happened to Ethan?

**Why Did Ethan Disappear in Sirens on Netflix?**

In Sirens, Ethan Corbin III (played by Glenn Howerton) is introduced as a charming, affluent bachelor who falls in love with Simone (Milly Alcock), assistant to socialite Michaela “Kiki” Kell (Julianne Moore). Their romance remains secret due to Ethan’s close friendship with Peter (Kevin Bacon), Kiki’s husband.

Kiki eventually uncovers the relationship and manipulates Simone to reassess her feelings. She offers Simone a leadership role at her New York foundation, suggesting that Ethan might not be the key to her future. Simone, swayed by the opportunity and Kiki’s mentorship, agrees.

When Simone attempts to end her relationship with Ethan, she finds he has vanished from the island. This sudden absence raises suspicions that something dark may have happened to him.

**Is Ethan Killed or Missing in Sirens?**

Contrary to speculation, Ethan is not dead. The Sirens finale confirms that Ethan traveled to Buffalo, New York, to locate Simone’s estranged father and bring him to Port Haven. His intentions were romantic—he wanted to ask for Simone’s hand in marriage, hoping to receive her father’s blessing.

However, this action backfires. Simone never wanted to reconnect with her father due to unresolved trauma and resentment. She had long blamed him for abandoning her and her sister Devon (Meghann Fahy), leading to their placement in foster care. Ethan’s unilateral decision to involve her father becomes the tipping point in their strained relationship.

This ultimately prompts Simone to sever ties with Ethan permanently.

Did Kiki Have Anything to Do with Ethan’s Disappearance?

While Kiki Kell has significant influence and is known for her manipulative tendencies, Sirens makes it clear that she had no role in Ethan’s disappearance. By the time Ethan leaves the island, Kiki is entangled in her own marital issues, notably investigating Peter’s suspected infidelity.

Kiki’s involvement in Simone’s emotional evolution stems from mentorship rather than malice. Her goal is to prevent Simone from repeating the same mistakes she made by marrying into wealth and losing herself.

What Happens to Ethan After the Breakup With Simone?

Ethan’s heartbreak pushes him into an emotional downward spiral. Unable to process Simone’s rejection—especially after planning to propose—he becomes erratic. His ego, bruised by the breakup, overrides his judgment.

In a drunken state, Ethan confronts Simone near the Cliff House. While she attempts to defuse the situation, Ethan loses his balance and accidentally falls off the cliff. The scene is intense but pivotal in showing the culmination of Ethan’s unraveling.

Importantly, Simone is not responsible for Ethan’s fall. The incident is portrayed as the result of Ethan’s impaired state and emotional instability.

**Did Ethan Survive in Sirens Finale on Netflix?**

Yes, Ethan survives. In the final episode of Sirens, it’s revealed that he broke both of his legs from the fall but lived. His physical injuries mirror his emotional wounds, and he places the blame squarely on Simone for his condition.

However, Ethan’s downward trajectory is largely due to his actions. His need for control, entitlement, and failure to understand Simone’s emotional boundaries contributed to their breakup and his subsequent downfall.

Peter steps in to protect Simone from Ethan’s rage, signaling a shift in alliances and underlining how deeply Ethan’s relationships have deteriorated.

**What Is Ethan’s Final Role in Sirens Ending?**

Ethan’s role in the finale is to embody the consequences of unchecked ego and emotional manipulation. By the series’ end, he is a shadow of his former self, both physically and emotionally broken. His fall serves as a cautionary arc—showcasing how love without understanding can become toxic.

Although he brands Simone as a “monster,” the narrative clearly portrays his downfall as self-inflicted.
