Doctor X Episode 10 – K-wave Insider

As Hyeona’s surgery begins, doctors who took the same oath must choose between the voting hall and the operating room.

Spoiler warning: This post covers the main plot and final scene of Doctor X: Mafia in White Episode 10.

The smallest child lies in the biggest operating room.

In Doctor X: Mafia in White Episode 10, eight-year-old Hyeona (Hyeon-a) is undergoing an operation planned to take 15 hours: the team must remove six abdominal organs, cut away a rare tumor, and put the organs back in. At the same time, doctors gather in an auditorium to vote on a mass resignation. Hospital director Bu Seunggwon (Bu Seung-gwon) takes the microphone and asks where they should be right now: in the voting hall, or in that operating room? That night, after the surgery, surgery professor Do Yunsik (Do Yun-sik) says, “Today, I was a doctor.” The next morning, the hospital moves to discipline the doctors who helped save her.

Doctor X Episode 10 Recap: From the Voting Hall to the Operating Room

What She Learned in an Operating Room Under Fire

In a flashback, shells are falling outside an operating room. Jang Heesook (Jang Hee-sook) loads a pistol and tells Gye Sujeong (Gye Su-jeong) to save the patient first. Today, Director Jang runs the doctor placement agency that sends Sujeong out to hospitals on contract. Sujeong picks up the scalpel and keeps talking to Director Jang to keep her awake.

Director Jang tells her to think of the person who donated the heart, the person receiving it, and the person who could have received it instead. If Sujeong fails, three hearts are lost. A doctor stays by the patient’s side to the very end.

“For this patient, you’re the only one. So you’re everything.”

Back in Hyeona’s operating room, it’s Sujeong who tells Director Jang to focus.

Why Bu Seunggwon Took the Microphone

The vote on whether to submit resignations en masse begins. Bu Seunggwon and surgeon Bae Heunggon (Bae Heung-gon) stay in their seats. When Kim Changsu (Kim Chang-su), president of the Seonam City Medical Association, barks at them, Bu Seunggwon walks past the ballot box and takes the microphone.

Only one operating room is running in their hospital today, he says. The smallest child is lying in the biggest operating room. Hospital after hospital turned her away, and this operation is her last chance.

“Where should we be? Here, holding our patients’ lives hostage, or in that operating room? This is my choice.”

Bu Seunggwon tosses the microphone aside and walks out. Bae Heunggon asks resident Ma Seonggyu (Ma Seong-gyu) to come with him. He tells Seonggyu to think about how he’ll feel when he looks at his seven-year-old nephew. Seonggyu stays. Bae Heunggon runs to the operating room alone.

The motion passes with 92 percent in favor. Seonggyu begins, “The reason we became doctors is…” and stops. Bu Seunggwon’s words come back to him. Kim Changsu takes over the microphone, and the hall breaks into applause. Seonggyu looks hollow.

“I’ll Make Sure Hyeona Grows Up”

Bu Seunggwon and Bae Heunggon enter the operating room one after the other. Both are taken aback to see Director Jang in scrubs. Do Yunsik asks, “Wait, if you’re here, what about the vote? You did vote first, right?” With more hands at the table, the operation gains momentum.

Kim Changsu and Guseo Foundation chairman Gu Bonpyeong (Gu Bon-pyeong) show up in the observation room and demand that the team stop. The surgery has no Institutional Review Board (IRB) approval. Sujeong answers that Hyeona has never once given her mother any trouble. “I’ll make sure Hyeona grows up.”

As the two men keep shouting, Bu Seunggwon finally calls out, “Gu Bonpyeong!” He invokes his authority as hospital director and says the operation will go ahead. Anesthesiologist Jo Wonjin (Jo Won-jin) switches off the speaker. When Kim Changsu threatens to call in hired security, Ma Seonggyu intervenes. If the cameras catch them breaking up a surgery, he says, it won’t do the strike any favors.

“Don’t Bow”

Emergency physician Kim Seongjin (Kim Seong-jin) joins them. The team rebuilds the blood vessels with artificial grafts, then puts the organs back in. The clamps come off. Everyone waits for the organs to regain their color. Finally, the color returns, and Hyeona’s blood pressure holds. Some of the doctors are in tears.

“The surgery is over.”

When Sujeong starts to bow, Bae Heunggon stops her. “Don’t bow. You bowed and asked us to help. That’s why we’re here.” He tells her to finish the way she always does. Sujeong takes Director Jang’s hand, and together they rest their hands on Hyeona’s chest. Outside the operating room, Hyeona’s mother sinks to the floor.

“Today, I Was a Doctor”

Director Jang offers to treat the whole surgical team to dinner. They expect a feast and end up at a modest snack bar. She says restaurants closed early because of the strike, but no one quite buys her excuse. Even the ones who grumble are soon eating happily.

They toast with little bottles of yogurt drink, and Director Jang hands out her business cards. When Bu Seunggwon tells Sujeong how hard she worked, she finally says it back: Sugohasyeosseumnida. It’s what Koreans say to acknowledge someone’s effort, especially after finishing a hard job together. Director Jang’s staff are delighted. It looks like Sujeong has made friends.

Director Jang carries the sleeping Sujeong on her back to the bus stop and tells intern Park Taekyung (Park Tae-kyung) how they became family. Sujeong is the daughter of an older friend to whom Director Jang owes a great deal. Taekyung tells her about the boy he used to be, the one who neither smiled nor cried at the children’s home where his parents found him. “It’s a good thing, having a family,” he says.

Outside a convenience store, Do Yunsik tells Bae Heunggon that this was probably Bu Seunggwon’s last surgery. The center of his vision is fading. Do Yunsik says he’s worked as a doctor for years, but he isn’t sure he ever really lived as one. He’d forgotten the weight of saving lives every day.

“Today, I was a doctor.”

The two realize they’d forgotten there would be a tomorrow. Do Yunsik laughs. “After today, I don’t think we can go back to the way things were. Still, we’re screwed.”

At home, Ma Seonggyu looks at his nephew and starts a message to Bae Heunggon, then hesitates. A message from Bae Heunggon arrives first. The surgery went well. The kid has a chance now.

The Next Day, an Empty Hospital

The next morning, the hospital is strangely quiet. A notice arrives in Chairman Gu’s name. The doctors who took part in the surgery are suspended from duty, and Sujeong’s contract is terminated. The IRB, which never convened before the surgery, finally meets. It’s clear what the meeting is for. In the middle of it all, word comes of an accident at an intersection, and Kim Seongjin goes to treat patients despite his suspension.

Gu Bonpyeong and Kim Changsu run the hearing. Kim Changsu accuses the team of putting Hyeona at risk by operating without approval. The doctors explain why the surgery had to happen, but neither man is listening. Bu Seunggwon is removed from his post, Sujeong’s contract termination stands, and the other professors face suspensions of one to three months.

As Gu Bonpyeong and Kim Changsu are leaving the room, still chuckling, Director Jang arrives with Hyeona’s mother. “Then I’ll sue,” the mother says. She’ll sue every doctor who took part in the surgery. Then she adds that she’ll sue the main hospital and the branch as well. If the main hospital hadn’t sent Hyeona away saying there was nothing it could do, would the branch ever have needed to operate?

It was Director Jang’s idea. She asked Hyeona’s mother to say she would hold the hospital and foundation responsible too. When Kim Changsu tells them they’re throwing an egg at a rock, Sujeong answers that you don’t throw the egg to break the rock. You throw it to leave a mark. Let enough eggs hit the rock and people will start to notice where the stink is coming from.

The disciplinary action is put on hold. Later, Hyeona’s mother sits down with Director Jang and Sujeong and asks Sujeong to say those words again.

“I never fail.”

The Surgeon Behind His First Transplant

One of the patients injured in the accident is declared brain-dead. Then the hospital learns that Kim Seunghyo (Kim Seung-hyo), founder of the White Wings Medical Center in Cuba, is coming to the branch for a heart transplant. In a photo, he’s holding a child Sujeong saved. Director Jang’s face hardens at the news. Taekyung and Wonjin look at his photo on the hospital wall, seething.

Kim Seunghyo has two reasons to choose the branch. Jo Wonjin is there as his designated contact, and he wants the surgeon who performed his first transplant to operate on him again. That surgeon is Gye Sujeong. In her memory, though, he’s the man who stabbed her in the leg with scissors when she walked into a burning medical center.

Two days later, Kim Seunghyo is admitted. Sujeong finds Taekyung pressing a pillow over his face while Wonjin watches. She rushes in and stops him. Kim Seunghyo grabs her arm.

“Long time no see, Doctor X.”

What Makes a Doctor a Doctor?

Episode 10 opens with Director Jang’s lesson. In an operating room under fire, she tells Sujeong that a doctor stays by the patient’s side to the very end. That’s the duty she took on and the reason she became a doctor in the first place. Bu Seunggwon puts the same question to the people in the auditorium: The voting hall or the operating room? Where does your patient need you right now?

This isn’t the first time Do Yunsik has saved a life. As Bae Heunggon says, surgeons do it every day. What Do Yunsik had forgotten was the weight of it. In Episode 9, he walked out of the vote. In Episode 10, he stays with Hyeona until the operation is over. For the first time in a long while, he feels what it means for a child to have a tomorrow because of something he did. That’s where “Today, I was a doctor” comes from.

That’s also why his line about going back to the way things were stays with me. After choosing to stay with Hyeona that day, he can’t simply go back to that seat. To me, that’s what makes a doctor a doctor. A license gives him the right to practice, and an oath tells him what he owes his patients. That day, he chooses to stand beside one. “Still, we’re screwed” is his way of admitting he knows what it might cost him. I don’t hear any regret in it.

Why Did Gu Bonpyeong and Kim Changsu Put the Disciplinary Action on Hold?

The answer lies in the egg and the rock. In Korea, throwing an egg at a rock means taking on someone far more powerful than you. Kim Changsu uses the saying to tell Hyeona’s mother that one parent can’t beat a hospital foundation.

Sujeong turns the saying around. The egg won’t break the rock, but it’ll leave a mark. Keep throwing them, and sooner or later the smell draws attention. The Korean word gurida can mean both “to smell foul” and “to be shady.” The joke lands because Sujeong means both: the smell is what finally gets people to look at the rock.

I don’t think Gu Bonpyeong and Kim Changsu backed down because they expected to lose in court. A lawsuit would draw attention to the main hospital that turned Hyeona away and to the review board that found time to meet only after the surgery. The mother’s threat works because it makes the foundation answer for what it did, too. That’s the mark they can’t afford to leave.

Who Is Kim Seunghyo of White Wings?

In Episode 9, “Doctor X” was a name that carried both respect and contempt. Kim Seunghyo says it the way you’d greet someone you’ve known for years. The photo shows the founder of an organization that set up medical facilities in developing countries. Sujeong remembers the man who stabbed her. Why he wants her to operate on him again, and why Taekyung tried to kill him, hasn’t been revealed yet.

What we do see is Sujeong stopping Taekyung from killing the man who hurt her. In the opening flashback, Director Jang tells her to stay by the patient’s side. The episode ends with a harder question: Can Sujeong do that when the patient is Kim Seunghyo?

Do Koreans Really Drink Beer Outside Convenience Stores?

Yes. Korean dramas often show people drinking canned beer at plastic tables outside convenience stores. Do Yunsik and Bae Heunggon do it in Episode 10, and Bu Seunggwon and Do Yunsik sat outside a convenience store in Episode 9. It’s a common sight in Korea, especially on mild evenings when the tables outside neighborhood stores fill up.

Beer bought at a convenience store and drunk out front is called pyeonmaek, short for pyeonuijeom maekju, or “convenience store beer.” There’s a related custom called gamaek, short for “shop beer”: you buy a beer at a small neighborhood shop and drink it there with simple snacks.

The appeal is simple. It’s cheaper than a bar, and there’s no need to book a table or make a night of it. You can just sit for a while on your way home from work. If you visit Korea, it’s worth trying once. Buy a can of beer and a bag of chips, and grab a seat outside.
