Shyam has to b the kidnapper

I think Shyam is without doubt the kidnapper. I reackon Khushi doesnt wanna disclose the fact she feels Arnavs in trouble to the rest of the family so decides to call someone she trusts for help. It might turn out that she phones NK for help. that way his entry seems logical and he is Khushis friend afterall so he may indeed help Khushi. x
