Greetings guys
Sorry but i am not new to this forum but quite silent reader of this forum but i followed this show from day 1so i am new to this forum but you can see my post on maths forum .
Accutally followed both the show .
Now coming to your ques .its an very old trick to boost the ratings by maker and pH .
The saut track always bring some high voltage drama and its loved by trp audience .
The devil saut and innocent leads are favourite dish of any pH and producer in Indian television industry .
Reshmi is such a pH who create lots of drama in an unwanted element which is needed not on the current storyline .
If you gone through the concept of the show then the main plot is existed long back and now the story is revolve around the sub plot .
Who knows next ghost are coming ?
Sorry for boring you but kavita entry is created because of drama and rift between saswan and another things makers thought because tejsawi quit the show so they need second lead so they thought of making kavita as a second lead and antagonist also .
