Doctor X Mafia in White Episodes 5–6 Recap & Ending Explained
Written by Huzaifa
Spoiler warning: Full spoilers for Episodes 5 and 6, including both endings.
Na Dae-il can explain away someone else’s suffering. The possibility of experiencing it himself sends him into a panic.
This Doctor X Mafia in White episodes 5-6 recap follows the fallout from his abuse of a patient, then a case that challenges Su-jeong’s confidence in a different way. Doctor X: Mafia in White moves from an ugly betrayal to a patient who fears what successful treatment might take away.
Previously On: The Initials Inside Kwon’s Body
In Episodes 1–4, Gye Su-jeong repeatedly rescued patients while clashing with the hierarchy at Guseo University Hospital. Na Dae-il arrived looking like a possible ally, until emergency surgery on pharmaceutical representative Kwon Chung-hyeon revealed D.N. marked on his liver—the initials of the doctor he had trusted for years.
Episode 5: Kwon Deserves to Know
The operation continues, and Su-jeong has Park Tae-kyung photograph the inscription. Kwon survives. His family’s gratitude makes the discovery harder to carry: they are thanking doctors while the team debates whether to reveal what one doctor did.
Jo Won-jin worries that telling Kwon will leave him with knowledge he cannot escape. Su-jeong insists that information about his body belongs to him. Reporting to the institution and informing the patient are separate decisions.
At home, the marks also disturb Su-jeong’s sleep. Her wartime nightmare links the violation in the operating room to violence from her past. Her anger has a history, even if the hospital knows little about it.
When Kwon learns the truth, he initially avoids confronting it. His pregnant wife will need the hospital, and his work depends on relationships with doctors. Speaking up could threaten far more than a single professional connection.
That hesitation is painfully believable. A patient should not have to calculate the cost of objecting to his own mistreatment.
Dae-il’s Excuse Makes the Betrayal Worse
Dae-il continues behaving as though nothing serious happened. When Su-jeong challenges him, he treats Kwon’s survival as justification: the inscription is hidden, and the man is alive.
Kwon cannot separate those things so easily. He later breaks down over the discovery. The mark may be invisible from outside, but knowing it exists changes how he sees himself and the doctor he once considered his saviour.
Su-jeong brings Hee-sook into the situation. The balance begins shifting when Dae-il’s own test results lead to liver surgery.
Now he is the unconscious patient depending on someone else’s restraint.
A Plate of Food Sends Dae-il Spiralling
After surgery, Dae-il wants the operating-room recording. Getting access proves awkward, and his anxiety worsens when Su-jeong writes D.N. in ketchup on his food.
He discovers that his intended surgeon did not perform the operation: drinking had disqualified the doctor, leaving Su-jeong to take over. The footage offers no reassurance because it does not clearly reveal her work.
The camera restrictions that protect surgeons from scrutiny suddenly feel intolerable to a surgeon who needs answers.
Dae-il confronts Su-jeong in the emergency department. The confrontation turns violent, and he cuts her arm with a scalpel. Hee-sook intervenes, overpowering him before the police become involved.
I find the ketchup scene more disturbing than a shouted confession would have been. Dae-il already knows why a patient might feel violated. He only takes that feeling seriously when he imagines himself on the receiving end.
Episode 5 Ending Explained: What Did Su-jeong Actually Do?
Dae-il is removed from his position, and Su-jeong returns to surgery. Tae-kyung gives her a lab coat bearing her name, a small gesture of welcome after the hostility surrounding her arrival.
Bu Seung-kwon visits Dae-il in custody and vows to pursue the loss of his medical licence. That is a promise to act; the episode does not establish that the licence has already been revoked.
Dae-il then receives a pathology report showing no abnormal findings. The report deepens the sense that Su-jeong and Hee-sook have manipulated him. Her threats leave him afraid of what might happen whenever he next requires treatment.
The distinction matters: his fear is clear, but an equivalent inscription on his own liver is not shown. Tae-kyung’s unanswered doubt keeps Su-jeong’s methods uncomfortable, even as Dae-il’s hypocrisy becomes impossible to miss.
This Doctor X Mafia in White episodes 5-6 recap reaches its first turning point here: exposing one abusive surgeon creates an opening for Su-jeong, without making the hospital trustworthy.
Episode 6: Baraka’s Plea, Then a Dangerous Assignment
Episode 6 opens in Su-jeong’s wartime past. Baraka helps her escape a soldier and begs her to save his younger sister, who has been shot. Su-jeong heads into danger with him.
Knowing Baraka’s later fate makes this earlier meeting hurt. His faith in her ability gives her familiar confidence a much heavier meaning.
The episode briefly jumps to a former president’s arrival at the hospital and a dispute over moving another patient, then rewinds a week to explain that patient’s case.
Oh Sang-beom has lived with bullet fragments in his head since the 1980 Gwangju uprising. Seizures, pain and other symptoms have followed him for decades. The Magnolia Society wants the hospital to operate, while financial pressure leaves Bu little room to resist.
The surgeons fear a dangerous, highly visible failure. Su-jeong volunteers.
Hee-sook recognises the arrangement’s appeal to management: if things go badly, the outsider can carry the blame. Su-jeong’s willingness to help keeps making her useful to people who would happily discard her.
Sang-beom Carries More Than a Bullet
Su-jeong, Hee-sook, Tae-kyung and Won-jin travel to meet Sang-beom and persuade him to consider treatment.
His history centres on his older brother. As a child, he wanted to buy him shoes; the violence of May 1980 destroyed that ordinary hope. His brother’s body was never recovered, and Sang-beom has carried guilt alongside his physical injuries.
Su-jeong appears within a dream reconstruction of those events. She is imagining the suffering she is trying to understand, not literally appearing in his childhood.
Sang-beom communicates through a notebook and has come to regard his pain as punishment. Eventually, he agrees to travel for examinations. That willingness is tentative, and the people surrounding him have good reason to worry.
At the hospital, influential visitors turn his treatment into a publicity opportunity. Su-jeong blocks their access, while Won-jin uses the fire alarm to clear them out. Their protectiveness is welcome, but it cannot answer the question Sang-beom has yet to ask.
Why Sang-beom Refuses the Operation
Su-jeong notices that Sang-beom behaves as though his brother is still beside him. She explains that treatment could reduce the hallucinations along with his other symptoms.
He understands what that means: he might stop seeing his brother.
He refuses surgery.
This is the scene that stays with me. The doctors see a chance to relieve decades of suffering. Sang-beom hears that the person keeping him company could disappear. Medical confidence cannot settle that emotional conflict for him.
Su-jeong recognises the attachment because she still thinks about Baraka. Her willingness to give Sang-beom time shows a different kind of care from the forceful certainty she uses against senior doctors.
Episode 6 Ending Explained: The Helicopter Brings the Past Back
That night, Sang-beom disappears from his room. Tae-kyung and Won-jin check the surveillance footage and find that he has gone to the roof.
Meanwhile, former president Ji Du-seok is being brought to the hospital by helicopter. Its approach triggers Sang-beom’s memories of the gunfire that killed his brother while he protected him.
Tae-kyung and Won-jin reach Sang-beom and hold him back. His distress intensifies as the former president passes through. Su-jeong, delayed on the journey back, abandons the car and runs toward the hospital.
The ending leaves the emergency unresolved. Sang-beom has not undergone the planned operation, and Su-jeong has not delivered a reassuring rescue. SBS’s Episode 6 ending clip centres that desperate race to reach him.
The helicopter connects the hospital’s present priorities to the violence Sang-beom still experiences. The institution can mobilise immediately for a powerful man while struggling to protect a traumatised patient already in its care.
What This Means Going Forward
The question running through this Doctor X Mafia in White episodes 5-6 recap is who gets to decide what a patient needs. Dae-il dismissed Kwon’s right to know; Sang-beom’s case demands that Su-jeong respect a decision she desperately wants to change.
Episode 7 must address his immediate safety before any surgical victory. Su-jeong’s memories of Baraka also deserve closer attention in our Explanations coverage.
Do you think Su-jeong can help Sang-beom accept treatment next episode—and will Bu protect her when the former president’s arrival raises the stakes?
