The episode commences with a terrifying ambush on Ja Yoo and her comrades, leaving Chae Woon perilously wounded, teetering on the brink of life. In a desperate scramble to save him, Ja Yoo embarks on an uncharted path—performing groundbreaking surgery utilizing cultivated tissue within the shadowy bowels of Blood Free's headquarters, marking a triumphant maiden voyage for the company's avant-garde technology.
As Chae Woon claws his way back to consciousness, he unravels the sordid secrets lurking beneath the veneer of Blood Free. His revelation of the laboratory's sinister truth—a repository of organs and blood—is a shockwave that ignites righteous indignation within him. The moral quandary of harnessing such technology without fully grasping its consequences emerges as the narrative's cornerstone, pitting Ja Yoo's unwavering dedication to her craft against the specter of its potential harm to humanity.
The simmering tensions between Ja Yoo and Chae Woon finally boil over when he confronts her with the chilling possibility of porcine organs and blood coursing through his veins. Her steadfast denial and his subsequent eerie realization that he can perceive sounds beyond human comprehension create a chasm between them. Chae Woon's righteous indignation and accusations of her being motivated solely by greed culminate in a tumultuous rupture, as he brands her a soulless pursuer of profit before storming off in disgust.
Meanwhile, the relentless pursuit of Blood Free by Geum Seon-u is unveiled as a manifestation of a profound, personal aspiration that transcends mere monetary gain. His intimate conversations with an NBA athlete and introspective musings on the inevitable march of time hint at a yearning to defy the bounds of mortality, to prolong his youth into eternity. Flashbacks to his fervent discussions on cloning technology intertwine with his present-day eagerness to secure Blood Free, underscoring his obsession with a lifespan that spans millennia. This revelation imbues his character with a nuanced complexity, revealing that his motivations are deeply rooted in a quest for immortality, rather than solely financial gain.
The episode delves into the intricate web of political maneuvering within the company and the government's corridors. Over a breakfast table, the tense encounter between Geum Seon-u and his son, also named Seon-u, exposes the rift between them. The elder's frustration with the failed cloning endeavors and his eagerness to harness Blood Free's secrets simmer beneath the surface. Yet, the younger Seon-u advocates for a measured approach, counseling against impulsive corporate espionage.
In a poignant scene, Ja Yoo, her mind stirred by Chae Woon's words, steps into the lab, her hand hesitantly pushing open a door. This gesture hints at a subtle shift in her worldview, as she begins to question the path she's embarked upon and the moral implications of her actions. This introspective moment enriches her character, casting doubts on the future of Blood Free and its ethical compass.
The episode concludes on a note of uncertainty and impending peril, as the attack on Ja Yoo and her team, the uncovering of Blood Free's clandestine experiments, and the internal strife within the company and the Seon-u family converge to create a tense atmosphere. As shadows of doubt cast their pall over Blood Free, the struggle for survival—both physical and metaphorical—emerges as the central narrative thread, gripping viewers to the very end.
