I think that Vidya will give him the new medicines and sagar will get slowly get better and better. However, Sindoora will try to prevent this but in the process she will get caught. Then, her jealousy, money-mindedness and the fact that she wants the house, property etc will come out. She will be threatened by her husband that if she tries to stop sagar from getting better then her secret will come out. By the way, I think that her secret is that she is the one who caused sagar's problem.
Perhaps then there will be a leap and post-leap sagar would have been fully recovered and we will get to see some cool scenes between vidya and sagar.
This is what i think will happen in BMTD in future. Any comments?
