Karn was doing puja n after that ask if there's any1 for daan, just then kunti appears n says that his mother is here n want some daan. Karn ask her why she has abondaned him n she tells about her situation that she was unmarried and her father's pride that forced her to let him go.
Karn says that she was right, Son's life is nowhere when compared to father's pride. Kunti asks him to forgive her and tells him that she has now overcome everything and has come there as his mother.
Karn ask her about radha, that if she's his mother than what about her, radha was the one who taken care of him when kunti left him, she was the one who given him name n love, she was the one who who struggled to bring him up, he calls her as rajmata n ask to let him radha's son.
Kunti ask him to leave dury's side n he refuses to leave his friend, as he was the one who supported him when no one was with him n he was struggling, she ask if he's gonna fight against his brothers n karn says that it was her mistake that this situation appears, he was always infront of him but she never accepted him.
Kunti says that dury is doing adharam then y is he supporting him, karn replies that once dury did dharam, when in the competition feild every1 was against his caste, dury dnt care about caste n accepted him as his friend n given him that respect which he deserved, it was when his own mother dnt have the guts to support him. For that one day, Karn is ready to sacrifice himself for his friendship with Dury.
Kunti says that she can't tolerate his 5 sons fighting against their own elder brother, n ask him to leave dury's side n join pandavas, he can be called elder pandava, karn ask her to not reveal it to them as they follow dharam as they get to know of it they'll not fight with him n he'll surrender them to dury.
Kunti ask him wat can she do now, he ask her to let the war happen, Then he tells her that he was in dilemma and his wife asked him to ask her for answers. he was in dilemma to decide if he should keep his promise or to kill his brothers...Now he is clear after speaking to her. Since she came to him for Dhaan, He will give her a dhaan that she will mourn for only one of her six sons... He will not kill his 4 brothers, but he has to take on Arjun, as he has been his sworn enemy. So he has to fight against him and if he is killed in the war, he will die as Radhe's son. If he finishes Arjun, she will still have 5 sons alive.
He touches his feet n leave her crying alone, other side arjun gave the news that the peace treaty was declined by HP, yudi ask every1 to get set ready for war.
Precap: Krishna was in a feild n ask that after 3 days their will be start of yudh/mahabharat.
