Kids equation

Hey all
I was wondering how will be the kids of ragini Neil be with each other
We know ranbir doesn't like his mother but will he behave the same way with the siblings who is staying with her
I think the twins will hit off
Suhani and nishi might also be cordial with each other
In the new promo it's shown ranbir and Suhani comes with Neil to meet ragini
Suhani looks happy whereas ragini looks shocked
Is she shocked only to see Neil or Also to see his another child with him
We will soon get to know whether Suhani is raginis child or not
I wonder where the other twin is
He wasn't shown in the promo
