In the aftermath of a devastating explosion that left the city reeling, "The Killing Vote" Season 1, Episode 3, titled "The Shattered Illusion," delves into the complex dynamics of public perception, the blurred lines between heroism and villainy, and the personal struggles of its central characters. The episode opens with the tragic news of Uhm Eun Kyung's death and the erroneous report of Mu-chan's demise, a ploy by the police to conceal the truth—that Mu-chan, though injured, is very much alive.

The public, once enamored with Gaetal as a savior figure, now views him as a monster capable of sacrificing the innocent. This shift in sentiment is a testament to the fragility of public opinion and the moral ambiguity that lies at the core of the series. Joo Hyun, aware of Mu-chan's survival, grapples with the ethical implications of deceiving the public, a decision that Mu-chan insists is necessary for the investigation. Meanwhile, Joo Min, Joo Hyun's sister, uncovers a potential lead when she witnesses her teacher engaging in a suspicious transaction, possibly linked to the explosion. Her discovery sets off a chain of events that will draw her and her friend, Kim Ji-hoon, deeper into the conspiracy surrounding Gaetal.
As Joo Hyun investigates Mu-chan's condition, she uncovers discrepancies that lead her to the hospital, where she confronts a recovering Mu-chan. Their argument about the merits of lying to the public is cut short by the urgency of a new lead: the discovery of Gaetal's first video, which Joo Min and Ji-hoon believe was filmed at Seok-joo's house.
The trio, driven by a desire for truth, races to Seok-joo's residence, where Joo Hyun finds chilling evidence of the house's connection to Gaetal. The phrase "13th one was wrong" scrawled on the wall and newspaper clippings about Seok-joo's trial create an atmosphere of dread and foreboding. Mu-chan, alerted to Joo Hyun's findings, rushes to the scene, only to find her unconscious after being attacked.
The subsequent chase and escape of the mysterious assailant add another layer of complexity to the case. The next day, the police and forensics team descend upon the house, collecting evidence that could potentially unravel the mystery. Mu-chan and Joo Hyun visit Seok-joo in prison, where he cryptically alludes to his own actions and casts suspicion on Mu-chan, further complicating their relationship.
The episode reaches a climax with the revelation at Gi-chul's funeral, where his wife is gruesomely murdered in a manner reminiscent of Gaetal's modus operandi. This act not only shocks the city but also forces Joo Hyun to confront Mu-chan about his past with Seok-joo and his possible knowledge of the video's origin.
In a dramatic turn of events, Gaetal goes live, exposing Mu-chan's survival and challenging the public's perception of justice. He positions himself as a figure of accountability, demanding that Mu-chan define his version of justice. As Mu-chan and Joo Hyun face the press, Mu-chan vows to apprehend Gaetal, setting the stage for a final confrontation.
The episode concludes with a sense of foreboding as Gaetal's actions and Seok-joo's words sow seeds of doubt in Joo Hyun's mind, threatening to undermine the fragile trust between her and Mu-chan. Despite these challenges, their partnership grows stronger, and they remain steadfast in their pursuit of Gaetal, who shows no signs of ceasing his killing vote.
"The Killing Vote" Season 1, Episode 3, is a gripping installment that explores the consequences of deception, the complexities of justice, and the lengths individuals will go to uphold their own versions of right and wrong. As the characters navigate this moral quagmire, the audience is left to ponder the true cost of seeking justice and the impact of public opinion on the pursuit of truth.
