sonu and karna watched how one by one kaurav force decline and one by one all the kaurav dies.
when karna asked who will win war, so sonu said that time kaurav will lose.
After seeing this karna asked how do you know about ka it, then sonu tells him that i know this form the start . what will happen to you? and kaurav vans disaster, which I can stop but.
karan asked why didn't you stop the war aur wrong things happen this year. Then sonu said I cannot disturb the time line or change anything, vashudev also know s about it form the start but he also cannot change the destiny.
karna asked sonu how you changed by saving me.
sonu said karna, you will die in this battle which I full filled by creating scenario of your death with the help of vashudev. now you cannot go start fighting against pandav because you will come with me in another world where their is no ruler of a kingdom ,people are free to walk but their police like sainik in that world.
karna when we both will go, then karan mother said all them, karana see sonu ,then sonu said it is right.
After that sonu , karna and other started watching what happening in the kurukshetra. After one year mahabharat war ended the kaurav have no one all of them died in this war and pandav become the winner of this war.
in the last brahmastra was used by both arjun and ashwatthama. For avoid the disaster brahma has to come to stop the brahmastra.
After that sonu went to vashudev for take permission to leaving this world and also taking the subhadra with me. sonu meet arjun, then arjun said bharata sonu very happy to see please forgive me for killing your brother, karna wanted go to the after I tell him not go, he made his own choice. then arjun left sonu enter in the room then said to vashudev I am leaving this world, and came here to take your permission to leave .
vashudev said ok you can go but come with my sister to visit me .
Then sonu left dwarika with subhadra .
