Ye chupdi chupdi Deepa Chachi seems evil.
The way she smiled made me think it was not out of the goodness of heart that she joined hands with Rohit to punish Sonakshi.
Even before this she was in on the Nishi plotting against Suman thing. I have a feeling she can turn negative later on.
EDIT 29 JULY:
She looked so shady when she called up Rohit in Monday's episode. She was sitting, sipping wine like a don, giving villainous looks. What if shez related to the person who died on 26 Sept and wants to seek revenge on Sonakshi n Rohit.
Afterall, we dunno who was behind that daag on Praniti's dress, which made her exchange the dress.
