As per me it would be either Ichcha or Vansh .... As the prime motive of CV's is to torture Ichcha and if Vansh knows about her innosence then she will be happy .... so that possibility is ruled out ...
My vote goes for Ichcha .. she will be shoot and killed ... as CV's involved now in kill good people mode in all CV's serial ....
If their quota for Ichcha torture is still not over, then it would be Vansh... tappu would kill him and would blame Ichcha .. so everyone would hate Ichcha and she would land up in jail ... he he he
Otherwise Ichcha dies and Masoom marries Vansh :D
After seeing CV's ways of serial .... I do not expect anything good
