There have been several topics on Dev's missing mom and sister.
These are my views. The mom never looked as if she belonged to khurana family.
Even the sister she was greedy, always all over Geet's jewellry.
She never looked like a rich gal. See Anvesha how she talks and behaves.
I think Mom is like Dai ma who raised Maan and Dev. May be Dadi ma sent her with Dev when maan threw him out. And kamya is her daughter. So they are not really the family.
Because the Dai ma loved Dev very much she acted as his mom.
I remember her calling Chotee saab from Hoshiyarpur.
So what do you think?
