This exactly my point is..U are may b missing two things 1.Kabir is relaxed and feeling truimphant becoz The constant threat of Vansh"s exsistence is not there. That was the time Riddhima initially wàs ready to give her life, and later if not love she trusted him.He had continuedly get his motherand Riddhima 's support.But now Riddhima loathes him and after his cover being blown she will consider him as her enemy.With his overconfidence of Vansh 's death and his loking down upon attitude towards Riddhima will bring his downfall. I presumed u liked Kabir too much thats why u are unable to see that He is thinking that he has won the war. And in such cases shrwed ppl like him too get relaxed and cimmits mistake.Kabir too will do the same.Absence of Vansh is speaking in support of his victory too loud.You never know this may b a well craft plan of Vansh. As i am repeatedly saying that he has changed his moves did not give up his mission.
Vansh never really underestimated him.It was the fact that he was equally crafty asKabir was. Its just that he had always put up his aura and swag infront of him. Kabir himself admitted that Vansh is a hard nut to crack. He was hunting Vansh since two years and then after getting no success he send Riddhima as a spy And I agree Vansh has done some mistakes even Riddhima did some blunders.As the proverb run by "Too error is to Human"Riansh fell in love but they were never in trust thats the magnum loophole of their relationship. Kabir utilized that but now as he is apparently no more in this world Kabir will commit mistake.He is thinking that he had won the whole battle. Neither Vansh nor Kabir are Gid so the turn of comitting mistake will emerge for both. And we all agree that Riddhima was indeed responsible but we cannot blame her entirely. I am sure she will suffer and bear the brunt of Vansh 's anger hatred and distant to a large extent along with Kabir experiencing his dooms day.
