Ghar Ki Laxmi Betiyaan - The end of Bhavishya ?

Many months ago, Saraswati was shown as having got married to Bhavishya, the worst time of her life. He caused immense torture to her, and then tried to burn her. She finally got out this problem, and Bhavishya was diagnosed as being mentally ill and sent to a mental hospital.
And then the rule of the doubles came in; Durga met a young man who looked exactly like Bhavishya. The family was very suspicious of this new person, but slowly everybody (and hesitantly Sawaswati) got over the whole worry and accepted him. He married Durga, and things seemed to be fine. He was actually genuine, and then Bhavishya, having got out of the hospital in some way, kidnapped this guy and took his place. And then he started plotting again.
He started drugging Durga, and had more plans to cause problems to the rest of the family. He also caused immense tensions between Durga and Saraswati, and eventually for Saraswati to be declared as mad and sent off to a hospital. But now his game seemed to be up; both Karan and Lakshmi realized his truth and plotted as to how to expose him. And eventually, the sisters and Savitri cornered him, and burned him to death (not good, you should never show using murder for any kind of revenge; it is illegal and gives essentially wrong advice to people).
