Ok looks like everyone has had their say on this topic....so thought of posting mine as well.....
Well i am sure today that Shalini is not the spy....
1. If she really was the spy...they would not show her getting caught at the scene of crime....
2. Shalini is short and lil plump...the spy was sleek
3. Shalini has longer hair whivh is curly.....the py's hair has some kind of a step cut and is straight.....
4. Shalini....showed her cut today...the marks were much bigger whereas in yesterday's episode when the spy folded her shirt the marks were smaller nail marks and their were many more of them...shalini just had two big scratches....
The makers has suddenly diverted attention towards Shalini because it was becoming too obvious that Ritu is the spy........
