In the fifth episode of "The Worst of Evil" Season 1, the narrative delves deeper into the complex web of loyalty, betrayal, and the high-stakes world of organized crime in Gangnam. The episode opens with a chaotic shootout, where Jun-mo, despite being injured, manages to fend off the attackers without causing any fatal casualties. His actions, though reckless, earn him a level of trust from Gi-Chul, who acknowledges Jun-mo's saved his life twice as "saved his life twice".
The aftermath of the attack leaves Gi-Chul feeling responsible and upset,
leading to a heartfelt conversation with Jun-mo in the hospital. It's here that
Jun-mo inquires about the gang's smuggling operation, to which Gi-Chul promises
to reveal everything in due time. This exchange marks a turning point in their
relationship, as Gi-Chul begins to see Jun-mo as more than just a pawn in his
criminal empire.

Eui-jeong, furious with the police's handling of the situation, offers her assistance to the officers, demonstrating her concern for Jun-mo's well-being and her willingness to go to great lengths to ensure his safety. This act of desperation highlights the personal stakes involved in the ongoing conflict.
As the investigation into the attack continues, Gi-Chul enlists Seo's help to identify the traitor within their ranks. Seo's investigation leads him to Oh-hyujin, who is revealed to be the one who betrayed the gang. Jun-mo's intervention during Oh-hyujin's interrogation shows his compassionate side, as he pleads for leniency on behalf of the betrayer. Gi-Chul's decision to promote Jun-mo to a position of authority within the gang is a testament to the trust he has placed in him.
The episode also introduces a new development in the form of a visit from the Chinese, which prompts Gi-Chul to prepare a special welcome. The initial plan for Jungbae to meet with the Chinese is altered when Gi-Chul receives a call from Eui-jeong, suggesting a deeper connection between them. This subplot adds another layer of intrigue to the story, as it becomes clear that Eui-jeong may have her own agenda.
Seo's undercover operation at the hospital provides a brief respite from the tension, as he confirms Jungbae's innocence in the ambush. However, his actions lead to the death of the gang head, further complicating the relationships within the gang. Gi-Chul's private conversation with Jungbae reveals a hint of mistrust, as Jungbae expresses concern over Gi-Chul's meeting with Eui-jeong, a police official. Jun-mo's visit home and the subsequent dinner with Eui-jeong humanizes him, showing a side of his character that is often overshadowed by his involvement in the gang's activities. This scene serves as a reminder of the personal lives and relationships that exist beyond the criminal underworld.
The episode concludes with a series of events that set the stage for future conflicts. Jun-mo's encounter with the young woman at the airport and the subsequent realization that she may be connected to the smuggling operation adds a new dimension to the story. The appearance of the suitcase and the man from the airport raises suspicions about the nature of the smuggling operation and the possible involvement of Jungbae.
