I think this going to happen

after lakshya's betrayal...it will open the eyes of ragini...and she realises how due to her obsession...she betrayed so many relationships...the guilt will haunt her that she attempt to kill her sister whom love and support her the most...she might attempt suicide...swara will try to save her but ragini refuses and ask forgiveness to swara for whatever she has done and now she realises the pain of betrayal...ragini will commit suicide which will shock swara...saanskaar comes there and swara ask him to bring back her sister...saanskaar saves ragini...they bring her to the hospital...ragini might be in critical condition...loony maasi-daadi will blame swara...while swara will blame lakshya for ragini's condition...swasan will stay ragini as swara insist to stay with her sister...emotional scenes b/w swasan and swaragini(ragini being unconscious)...ragini might come back to live...this time the bad soul of ragini is dead...the good soul ragini takes a re-birth...even lakshya's obsession is out of her mind...now she will redeem herself and rectify her mistake...and her first move to redeem herself is uniting swasan and protecting swasan relationship...swasangini will join hands together to expose kavita-loony maasi...

or it can happen kavita harming swara...but ragini saves swara...swasangini plays ghost drama to expose kavita-maasi...and ragini redeem herself and rectify her mistake...her first move is protecting swasan relationship
