i know how tuhsar will change into sujal(this is just my opinion nut iam pretty sure it will be soemthing like this)
akshat and kash are going to drag swayam to jail, during this time, tushar will remember his jail time and get his memory back, he will(in hero style) go to the witness box and sya that swyam is innocent. since sujal is alive and when someone is alive how can charge a person with his death. everyone will be shocked and akshat is going to scream at tushar as to what he is saying. tushar will answer that sujal is alove and is right there in fornt of everyone. then he is gpignto tell everyone that its him
tada👏
