As Parul has herself admitted , she is being portrayed negative for this track.Maybe it because, she will have to spend more time for her upcoming movie , she is taking a backseat.And maybe Rajanji is letting Sara lead the show coz' she will not be in the movie.
OR
Ragini is bad only for the current track and will be back to lead in the next one.
I believe it not always "Do or Die" , life happens in between the two!š
So lets be patient and see.š
