Today Prachi herself said Sandhya is the better dancer, so shouldn't the better dancer be winning?
Personally if the competition is about the most improved, then Jay should win, not Prachi or Sandhya as both were always dancing well. Jay was so so before, but now he seems to be dancing really well.
So if the best dancer has to win, it should be Sandhya, if the most improved has to win, it has to be Jay. So who do you think should win?
