In the second season of Arcane, in the fifth episode, the series suddenly drops the mask. Without loud statements, without obsessive drama, he just takes it and shows the truth. The one that makes you feel uneasy. It is here that the identity of Dr. Korin Rebekah is finally revealed to the viewer. Not as another plot move, but as a painful confession, which we were led to for a long time and carefully.
Rebekah is not just a name from the Piltover archives. This is a man whose life was once filled with meaning, respect, and a future. The series slowly, almost carefully, takes us back to his past, showing who he was before the world recognized him as Sinjeda. And the further you look, the clearer it becomes: madness does not arise out of nowhere. It grows out of pain that has been ignored for a long time.
Dr. Korin Rebek was once a model of Piltover science. He was appreciated, his ideas were supported, and his name was respected. He believed in progress, in reason, and that technology could improve life. But life rarely follows logic. Losses come suddenly and mercilessly. One after the other. And at some point, the person just breaks down.
After the tragedies that befell him, Rebekah seems to erase himself from his former self. He leaves Piltover, renounces his name, and transforms into Sinjed— a frightening, cold, distant figure. But there is no emptiness behind this image. There is an obsession. There is a desperate attempt to hold onto meaning when everything else is already lost. Experiments don’t become a job for him — they become a lifeline. The last form of existence.
And that’s what makes the revelation so powerful. Arcane doesn’t justify Sinjed, but it doesn’t strip him of his humanity either. The line between the villain and the victim is blurred to the limit here. You look at it and find yourself thinking an unpleasant thought: would you have acted differently in his place? Dr. Rebek’s past casts a shadow over his every step in Zaun. And the series proves again that he knows how to tell stories in such a way that they stay inside for a long time.

Who is Dr. Korin Rebek in League of Legends?
Before the name Sinjed became synonymous with brutal science, Dr. Korin Rebek was a completely different person. In the lore of League of Legends, his story begins with hope. He was one of Piltover’s most gifted inventors, a man for whom technology had not only a function, but also a purpose. His prosthetics changed destinies — they gave people the opportunity to live fully, to feel needed, not broken.
But all this pales next to who Orianna was to him.
She wasn’t just a daughter. She was an extension of himself—inquisitive, talented, and surprisingly empathetic. Rebekah taught her how to invent, explained the principles, and showed her how to think. And eventually I realized: she goes beyond him. Faster. Deeper. Orianna became a genius, but at the same time retained a rare quality — compassion. She really wanted to help.
When the toxic gas disaster hit Zaun, Orianna did not hide behind the walls of Piltover. She went to a place where it was scary. Using her knowledge, she created respirators and filters, distributed them to those who suffocated. For the residents of Nizhny Novgorod, she became a symbol of hope — not a hero on a poster, but a living person who is nearby.
And it is at this moment that fate takes the cruelest turn.
In the chaos and panic, Orianna gave her mask to a little boy. Not from calculation, but from the heart. It was a simple, almost instinctive act. And fatal. Left unprotected, she inhaled the poisonous gas. The poisoning didn’t kill her immediately. It was slowly destroying the body, turning every day into an expectation of the worst.
For Dr. Rebekah, this was the beginning of the end. A scientist accustomed to finding solutions found himself faced with a problem that had no answer. But he couldn’t accept it. Love and despair push him on a path from which there is no turning back. He begins to replace his daughter’s organs with mechanical ones, hoping to gain time. The lungs first. Then everything else.
Every operation is a step between hope and horror. Orianna’s body survives, but her humanity is gradually disappearing. Emotions fade, memories fade. Their bond with their father is getting weaker. And as if that wasn’t enough, Rebekah himself falls seriously ill. Then Orianna makes a choice that is impossible to accept, but impossible not to understand.
She secretly replaces her heart by giving it to her father. The last thing that made her human. In its place, a hextec Ball appears, a mechanism that will become her companion and protection. With the loss of the heart, feelings disappear. This is how the Lady of the Clockwork Mechanism is born — a creature between a machine and the memory of a person.
Leaving Piltover and Zaun, Orianna goes wandering. Not running away, just because she has nowhere else to go back to. The golden dancer she leaves behind becomes a silent symbol of a lost life. A reminder of who she was.
The story of Korin Rebekah and Orianna is not just a tragedy. This is a story about how love can blind you, how good intentions can destroy you, and how far a person is willing to go if they are afraid of losing their most precious thing.
Arcane: The new face of Sinjed
In the classic lore of League of Legends, Sinjed has always been a frightening and almost inhuman figure. A chemist without morals, an experimenter without borders. Arcane breaks this image, showing that there is a man behind it — broken, lost, desperate.
In the fifth episode of the second season, “Blisters and Bedrock,” the fan theory is confirmed: Sinjed and Dr. Korin Rebek are the same person. Caitlin’s investigation into the Piltover archives becomes the catalyst. Their conversation is not just an interrogation. It’s a clash of the past with the present, where every word hurts.
After the loss of her daughter, Rebekah disappears from her former life. He becomes a Sinjed and goes to a place where the old rules no longer apply. His experiments are becoming more dangerous. This is how Shimmer appears, a substance born out of the hope of deceiving death. The pocket watch with Orianna’s photo, which he keeps, leads to a secret laboratory where she still exists — on the edge between life and mechanism.
Under pressure from Caitlin, Sinjed admits that everything he does is for the sake of trying to “heal” Orianna. Arcane shows not just a villain, but a father who couldn’t let go. The creation of Warwick, deals with darkness, experiments with Shimmer — all these are parts of one desperate attempt to regain what was lost.
That’s why Sinjed scares more than the usual antagonist. His actions are terrible, but the reason is too human. Arcane transforms him into a tragic figure, showing how love, taken to the extreme, can destroy everything around. This is not a story about evil for the sake of evil, but about pain that has not found a way out.
This is how Arcane proves once again that it can do the most important thing — bring League of Legends characters to life, filling them with fears, weaknesses and internal conflicts. Through themes of loss, obsession, and the boundaries of science, the series asks questions that have no easy answers. And that’s why this story catches, worries, and stays with us long after the end credits.
