I think what Cvs are aiming for here is this message...Your son is the one who cares for you, and he does not have to be biological.
Do you think CV swill go down this road. Read my post below carefully!!
My prediction on this track...
Most likely after Gayatri's taunt for Yash in the precap, Yash will seek solace in Radha's arms. Eventually, Yash may think he does not have a place in this house and will leave when Gayatri's taunts increase, after changing Akash though. So when he leaves, the Scindiya mansion will be lonely. Then what I think might happen is that Akash will get attached to Yash and Aarti and after they leave he will most definitely not like how Scindiya mansion has become.He will not like the decision of Gayatri to choose him over Yash and will go out and look for Yash and try to bring him back. When he does this, Yash will refuse and Akash will eventually move in with him. Like this, Gayatri will be left with only the other 2 of her sons who might still be angry at her for doing this. She will be yearning for her son and realize that the son she called illegitimate was the son that would care for her no matter what and left SM for her. She will realize that she broke him apart from her. She will be hurt so much that she will end up going to that very same son begging for him to come back. She will realize that she gave up the son who cared for her all his life and the son who gave up his happiness for her, for her biological son who still would not have ven developed the feelings for her that Yash developed for Radha.
I think CVs are going for the track that your son is the one who treats you properly, takes care of you and can give up his happiness for you. A son does not have to be biological to do this though.
