The Black Knight ending explained

Black Knight Finale spoilers follow

Social outcast and refugee Sa-wol (Kang You-Seok) has finally fulfilled his dream of becoming a “knight” or supplier. This means a lot in this post-apocalyptic world where clean air is produced and most citizens live in dire conditions.

He thought that the new position would give him a chance to help others by providing them with clean air. He also envisioned a better life for himself.

Well, it took all day to find out the truth about 5-8 (Kim Woo-bin) and his supplier group who are determined to stop the evil Ryu Seok in his attempts to eliminate all refugees for good.

How Black Knight completes the six-episode storyline Ryu Seok’s growing influence means his overthrow won’t be easy. Will the rebel suppliers be up to the task?

Here’s the breakdown Black Knight final.

The Black Knight ending explained

Song Seungheon, black knight


After five episodes of trickery, Ryu Seok (Song Seung-heon) was finally defeated.

Major Seol Ah (Esom) made an appointment with Cheonmyeong’s company president Ryu (Nam Kyung-eup) to inform him of all of Ryu Seok’s crimes.

His ghastly deeds include kidnapping mutant children (or those who could potentially be mutants) and slowly poisoning refugees by pumping air into their polluted neighborhoods.

Apparently it didn’t work fast enough because Ryu Seok also committed mass murder when he set off explosions in refugee neighborhoods.

Chairman Ryu is shocked to learn that his son has not only committed such crimes, but has also implicated the Cheonmyeong Group in various things.

Chairman Ryu quickly rectifies the situation and informs the president of his son’s actions.

He then transfers the management of Cheonmyeong to the government, which will now have control of the oxygen supply as well as plans for the supply and relocation of refugees.

Fresh from a failed attempt on his life by 5-8 and other vendors, Ryu Seok goes to his father and is informed of new developments that have thwarted his plans.

Father and son have an honest and heart-to-heart heart-to-heart conversation where the chairman tells Ryu Seok that he must face his crimes.

Two soldiers backed by the Ministry of Defense arrive to arrest Ryu Seok, but something seems wrong.

Ryu Seok makes a big show of the situation, then shoots the soldiers without hesitation before shoving the gun into his father’s hand and aiming for his own head.

Clearly fond of theatrics, he urges his father to shoot him, and after a tense moment of indecision on his father’s part, the gun goes off. Only Chairman Ryu was killed by the Minister of Defense, who turned out to be in cahoots with Ryu Seok.

They move quickly, enacting the final stage of their plan, which is to stage a coup d’état to capture the president.

Ryu Seok’s wicked deeds don’t stop there; continues to publicly blame the recent deaths of rogue suppliers, calling them terrorists, and a manhunt is underway for 12 disgraced suppliers.

Meanwhile, Sa-wol’s friend, Useless, discovered that the vaccines the refugees were urged to take were actually meant to kill them. Of course. The whole thing was orchestrated by the refugee-hating Ryu Seok.

He discovers this after the Mannequins have just embarked on their own physical examination, which includes a vaccine.

Useless runs to the medical examination center to warn them while one of the rogue suppliers raises the alarm. Useless tries to warn those in line to get vaccinated – including the Dummies – but his screams go unheard.

5-8 and Sa-wol came out of hiding to gather support, distracting with arrows and explosions, and it’s working. The crowd disperses.

Sa-wol tries to get to the Useless, but it’s too late. He is shot down by soldiers working for Ryu Seok. Grief-stricken Sa-wol runs to his friend but loses consciousness and is taken to Cheonmyeong.

In an ironic twist of fate, Sa-wol, a refugee, is the key to curing Ryu Seok of his deadly, mysterious illness. His mutated blood will cure him of his illness and is the reason he doesn’t die instantly.

Major Seol Ah and the suppliers head to Cheonmyeong to stop Ryu Seok’s slow poisoning and general massacre of refugees.

They make their way through the Core district, which is underground, and shoot, hunting down Ryu Seok.

However, Rhy Seok is too busy sucking the literal life out of Sa-wol as he receives a direct blood transfusion.

When he is alerted to the intrusion, Ryu Seok has the unconscious Sa-wol carried away from the operating room as he and his men go to observe the action.

In an ambush, the suppliers catch up to Ryu Seok’s right-hand man, Mr. Oh, and kill him while the minister holds the president hostage.

Major is able to save the president and arrests the minister for treason before being announced by the tannoy, instructing Ryu Seok’s defense team to drop their weapons.

Knowing that he has been defeated, Ryu Seok reacts like all petty villains do and doesn’t give up.

Instead, he retaliates by overloading the Air Core’s energy machinery, which will lead to a massive explosion that will destroy the entire core district.

As he says to the 5-8 who just caught up with him, “I won’t let the refugee scum have it,” and by that he means a safe place to live with clean air.

His actions cause mass panic and citizens begin to flee to safety.

During Ryu Seok’s brief speech about the villain, Sa-wol twitches slightly in his comatose state and the QR code on the back of his hand activates the wheelchair he is sitting in. This small random act is enough to distract Ryu Seok and he is shot by 5-8. Knowing he is dying, he decides to do it on his own terms and shoots himself in the head.

While the residents continue to break free on the surface where the refugees live, 5-8 moves Sa-will to safety while the other deliverers rescue the other mutated kids as hostages.

They manage to do so, but in an unexpected twist, Ryu Seok twitches. The camera stays on his face long enough to reveal the silver beneath his wounds. Why is it important? Well, because mutant bones are made of metal.

It seems Sa-wol’s mutated blood did the trick, meaning Ryu Seok should be able to heal faster and will likely be saved from the disease.

Before we can get any real answers, the energy core will explode and it will go up in flames along with the district core.

Little is known about mutated blood, and it is highly likely that their quick healing and ability to withstand what would be fatal for many could extend to explosions… Who knows?

For now, everything is fine with the world again. The president announces that they will start relocating refugees to a safer and better place.

He also announces that the classification system that divided citizens into refugees, general, special and core will be abolished. She then stepped on Ryu Seok’s evil legacy by promising to reform the housing and oxygen supply system so that citizens could live equally without discrimination.

We know that Ryu Seok is turning in his grave or writhing in the rubble of the main district.

The time jump shows that the president has delivered on her promises, as the much more stabilized and calmer 5-8s and Sa-wol comment on cleaner air and clearer skies during their oxygen supply.

However, if Ryu Seok is indeed alive and well, we wouldn’t count on it for long. We’re sure he’ll be plotting some form of revenge in a possible second season.
