I think the new generation leap will show them as mothers ...
If you notice something since start, they always had scenes going on back to back.
Jai and Bani had a bad marriage at start, Pia and Pushkar were happy couple. Then, the table turned and Jai and Bani fell in love Pushkar and Pia's marriage fell apart.
Same way, Ranvir and Raashi had a no-meaning marriage while Sahil and Rano were great together. Now Ranvir and Raashi are coming closer and Sahil and Rano are drifting from eachother.
I think they would be showing same with the young ladies in their pregnancy and motherhood..
HUM SAATH SAATH HAI..
