Hi guys I heard from a very reliable source that this is what is going to happen on Asthiva.
It looks like as we all guess, Neha is going to end up dying after giving birth to a girl baby (not so sure about the sex). As she dies she tells abhi and Simiran that they should get back to gether since they still love each other (promo). After she dies Simiran as usaul starts feeling guilty that she was responsible for her death etc, etc (2 to 3 episodes of rona and dhona) anyway in the end to kind of punish herself and prove the world simiran tells Abhi that she will not be able to marry him, and they will always remain as good freinds, and he will always be Aastha's papa.
After this the leap of 10 or 20 years happens (sometime in march), where they show every kid grown up. Simiran being a great mom and Astha 18 year old, trying to be a doctor or something. Of course surabh being a doting grandfather unchanged. Abhi being a great dad and bringing up his daughter of course with lot of help from his mom,dad, and of course good old Simmy (this reminds me of kali and kumud). Urmila out of jail, and sonu being 18 his conflicts with his dad, ria, and mom. Rias daughter coming back to India, and search of her father. And thus the story continues with lot of the above stories.
