Pia gave Jia a hint of what his next move should be.
He should know that he can't bring Bani back as BW.But Pia gave him a hint that he should marry DDG. Pia tells him that if Bani is Ddg she has no legal right on kids.
If only Jai is smart as a Business tycoon is supposed to be then he will force DDg to marry him so that she can claim the kids as her own being JW lawful wife. Ofcoure Ekta can think about some made up law hwereby JAi & DDG getting custody of kids & since kids have both parents Pia can't claim any custody.
But in Ekta land on;ly evil people get good ideas.
