Kyunki Saas Bhi Kabhi Bahu Thi 25th September 2026 Written Update: Karan Learns the Truth About Parth’s Death
The 25th September episode of Kyunki Saas Bhi Kabhi Bahu Thi brings two major emotional revelations. While Mihir continues to struggle with his damaged memories and becomes convinced that the people in India are his enemies, Mandira refuses to let him return to Tulsi. At the same time, Nandini finally decides that Karan deserves to know the truth about Parth’s death and shows him the evidence that changes everything he believed about Tulsi.
Mihir Gets Emotional With Mandira
The episode begins on an emotional note as Mihir spends some time with Mandira looking through old photographs.
The pictures bring back several memories from their past, leaving Mihir nostalgic. He looks at the photographs and gets lost in those moments, but their emotional conversation is interrupted when he receives a phone call. Mihir leaves after answering it.
Elsewhere, Anupam finds himself remembering his own time at Shantiniketan. The memories leave him thoughtful as the situation surrounding Mihir continues to become more complicated.
At the same time, Tulsi waits for Mihir and remains deeply worried about what is happening. She believes that Mandira can no longer keep the truth hidden from him.
Tulsi urges Mandira to tell Mihir everything.
Mandira refuses.
She firmly asks Tulsi not to reveal anything to Mihir because she believes that once the truth comes out, their entire lives could change. Mandira is clearly terrified of losing the place she currently has in Mihir’s life.
Nandini Overhears the Secret
While Tulsi and Tripti discuss the hidden truth, Nandini happens to overhear their conversation.
She immediately becomes suspicious.
Nandini realises that they are hiding something important, but she does not interrupt them. Instead, she quietly listens to what they are saying.
Tripti assures Tulsi that she will send the evidence. She wants Karan to discover the truth himself rather than simply being told about it.
According to Tripti, Karan needs to see the evidence with his own eyes. Only then will he understand what actually happened.
Nandini silently observes the conversation and realises that something much bigger is being kept hidden from Karan and the rest of the family.
Mihir Has A Terrifying Flashback
Later, Mihir suddenly wakes up and experiences disturbing flashbacks connected to an accident.
The memories frighten him, and his condition immediately worries Mandira and Anupam.
Mihir becomes increasingly confused and repeatedly asks what is happening to him. He cannot understand why these frightening images keep returning to him.
His fear becomes even more alarming when he tells Anupam that he believes the people in India are his enemies.
Mihir is convinced that they want to kill him.
Anupam is shocked by what he hears. He realises that Mihir’s memory problems are still affecting not only his understanding of the past but also his sense of identity and the people around him.
Mihir desperately wants to know why everyone seems to be against him and whom he can actually trust.
Seeing Mihir becoming increasingly disturbed, Mandira decides that she needs to calm him down. She gives him a sedative, and Mihir gradually loses consciousness before falling asleep.
Anupam watches the situation carefully.
He is increasingly concerned not only about Mihir’s condition but also about Mandira’s growing attachment to him.
Mandira Refuses To Let Mihir Go
Once Mihir is asleep, Anupam confronts Mandira.
He asks her what will happen when Mihir eventually learns the truth about his identity.
Anupam reminds her that Mihir will eventually discover that the people he currently considers his enemies are actually his own family—the Viranis.
He believes Mihir should be allowed to return to Tulsi.
Mandira refuses.
She makes it clear that she does not want to lose Mihir under any circumstances.
Mandira then reminds Anupam of everything she has done for Mihir. She explains that Mihir had forgotten everything, and she spent a long time helping him recover and return to normal life.
She stood beside him when he had no memory of his past.
For Mandira, that history has become a reason to believe that she has a right to remain in Mihir’s life.
She becomes emotional as she tells Anupam that she cannot simply let Mihir go after everything she has done for him.
Mandira admits that she cannot imagine living without Mihir.
Her words leave Anupam shocked.
He realises that Mandira’s feelings have gone far beyond simply caring for someone who is suffering from memory loss. Her fear of losing Mihir is now driving her decisions, including her determination to keep his identity hidden.
Nandini Finally Reveals Parth’s Death Truth
At the same time, Nandini reaches an important decision.
She decides that Karan needs to know the truth about Parth’s death.
Nandini shows Karan the video evidence.
Karan initially refuses to accept what he is seeing. He questions whether the video could have been created using AI and doubts its authenticity.
Nandini firmly tells him that the evidence is genuine.
She then explains what actually happened and reveals the circumstances surrounding Parth’s death.
The biggest revelation comes when Nandini tells Karan that Tulsi had taken the blame upon herself to protect her family.
Karan is devastated.
The revelation forces him to revisit everything he has believed for years.
He begins remembering how he treated Tulsi and starts questioning his own actions. He cannot understand how Tulsi could keep such a painful truth hidden for almost ten years.
For Karan, the revelation is not simply about discovering what happened to Parth. It forces him to reconsider his entire understanding of Tulsi.
Nandini tries to explain that Tulsi had her reasons for hiding the truth. She reminds Karan that Tulsi made the sacrifice because she wanted to protect her family.
Karan, though, is too hurt and angry to accept the explanation easily.
He struggles to process the fact that Tulsi carried such a massive burden for so many years while he remained unaware of the real story.
Karan Struggles With Tulsi’s Sacrifice
The truth leaves Karan emotionally shattered.
He begins connecting the events of the past and realises that the woman he judged and treated in a certain way had been carrying a painful secret all along.
For years, Karan had only known one version of what happened. Now, the evidence has forced him to look at the past from an entirely different perspective.
His anger, hurt and confusion collide as he tries to understand why Tulsi chose to remain silent.
Nandini attempts to make him understand that Tulsi’s decision came from her desire to protect the family, but Karan needs time to absorb everything.
The episode leaves him standing at an emotional crossroads.
At one end is everything he believed for nearly a decade. At the other is the painful truth that has now been placed directly in front of him.
Mihir’s Truth Remains Hidden
While Karan is dealing with the revelation about Parth, Mihir’s own truth remains hidden.
Anupam continues to worry about his deteriorating understanding of his past, while Mandira remains determined to prevent him from learning the truth about the Viranis.
Mihir still believes that the people in India are against him, unaware that the people he is being kept away from are actually connected to his real identity.
Mandira’s refusal to let him return to Tulsi means the emotional battle over Mihir is far from over.
The episode therefore ends with two families facing painful truths from their pasts, while the people at the centre of those secrets remain separated from the complete reality.
Precap
In the precap, Tulsi scolds Karan for his behaviour towards Nandini.
Overcome with emotion, Karan finally calls Tulsi “Maa.”
He tells Nandini that she kept him away from his mother for years.
At the same time, Karan makes an important point. He refuses to let Nandini stay away from their children because she is their mother.
The precap promises an emotional confrontation where Karan’s anger toward Nandini clashes with his newly awakened bond with Tulsi.
Kyunki Saas Bhi Kabhi Bahu Thi 25th September 2026 Review
This episode successfully keeps two heavy emotional tracks moving at the same time.
Mihir’s memory crisis remains disturbing because he genuinely does not understand whom he can trust. His belief that the people in India want to kill him makes his situation even more tragic, especially because he is unaware that his real family is being kept away from him.
Mandira’s track is equally complicated. She has clearly become deeply attached to Mihir after spending so much time caring for him, but her decision to hide his identity creates an even bigger problem. Her fear of losing him is understandable within the storyline, but keeping him away from Tulsi can only make the eventual revelation more explosive.
The biggest development, though, is Karan finally learning the truth about Parth’s death.
Nandini showing him the evidence gives the revelation more weight because Karan cannot simply dismiss it as someone’s version of the past. His initial suspicion that the video might be AI-generated also adds a contemporary touch to the confrontation.
The most emotional part is Karan being forced to reconsider how he treated Tulsi. After nearly ten years of believing one version of events, learning that Tulsi took the blame to protect the family naturally leaves him shattered.
And that precap? Karan calling Tulsi “Maa” is the emotional punch the episode was building toward. After years of distance, one word suddenly carries the weight of everything he has just discovered.
