Boss

Lallan betrayed Big Boss to his rival Dushyant at the roadside stop en route to Mirzapur. This betrayal was a calculated move by Dushyant to eliminate Big Boss and take control of his territory and operations. Lallan's treachery was part of a larger power struggle among the criminal networks in the region.

The boy who saved Big Boss at the roadside stop is Surya, the son of Satyakant Shastri. During the chaotic moment when Lallan's betrayal was revealed, this young boy intervened and prevented Big Boss from being harmed. Impressed by the boy's courage, Big Boss took him under his wing and gave him the nickname 'Boss.'

The boy's identity as Surya is later revealed when Satyakant reads an old incident report fifteen years later.

Surya was forced to leave his family after he killed the Sarpanch and his men in self-defense. As a child in Kurukshetra, Surya got into fights with the Sarpanch's son, which led to juvenile detention. After his release, the Sarpanch and his men attacked him, and Surya defended himself, killing them. This violent act, witnessed by Satyakant, Raghunath, and Shiv, caused his family to abandon him out of fear and shame.

Ayushman Thakur wants Shiv arrested because his sister Ankita has fallen in love with Shiv, threatening Ayushman's political plans. Ayushman intended to marry Ankita to his own son Vishal to consolidate power. When Ankita resisted this arrangement and chose Shiv, Ayushman used his political influence to have Shiv falsely arrested for crimes he did not commit, publicly humiliating Satyakant and the family.

Home Minister Pradhan places a contract on Shiv's life, paying Big Boss to kill him. This contract is part of Pradhan's alliance with Ayushman to eliminate anyone who threatens their political schemes. However, Pradhan later cancels the contract when he arrives at Ayushman's farmhouse, realizing the situation has become too complicated.

Big Boss acts as an informer to help expose twenty-five MLAs from Pradhan's party who were caught at a brothel with prostitutes. This politically explosive revelation, orchestrated with Boss's help, creates a major scandal that weakens Pradhan's political power and shifts the balance of the ongoing conflict.

Ayushman deliberately drives a truck into Tauji, Satyakant, and Shiv as they rush to reach Surya. This violent act is Ayushman's final attempt to eliminate the family and silence them permanently after his political schemes have unraveled. The collision results in Tauji surviving, Raghunath dying on the spot, and Satyakant being injured.

No, Surya did not kill his schoolmate. The truth, revealed by Tauji in his final moments, is that it was an accident. Despite this clarification, the sentiment of guilt still lingers and has haunted Surya throughout his life, contributing to his violent path and eventual abandonment by his family.

Vishal convinces Boss to free Shiv from custody, expecting Boss to kill Shiv once he's released. Instead, Boss helps Shiv escape from Ayushman's custody and reveals his true identity as Surya to Shiv. Later, Surya also plants a fake time bomb to force Shiv back into the open when he's hiding, ensuring they can confront the threats together.

Surya and Shiv are brothers, both sons of Satyakant Shastri. However, Satyakant believed Shiv was his only legitimate son while thinking Surya was the boy who saved Big Boss and became a criminal. The two brothers end up on opposite sides of a dangerous conflict until Surya reveals his identity and helps save Shiv from Ayushman's schemes, ultimately reuniting their family.

Surya takes responsibility for ensuring Ankita can marry Shiv, presenting the union to Tauji and Ayushman as a matter of honor and family defense. After Surya defeats Ayushman and the political conspiracy is exposed, Ankita and Shiv are finally able to be together, with the family's blessing.

Raghunath dies in the truck collision orchestrated by Ayushman. He is killed on the spot when Ayushman drives the truck into Tauji, Satyakant, and Shiv as they rush toward Surya. His death is one of the significant losses in the final confrontation.
