Apne apne bachae .. first the sister was surrogate .. then she was faking it .. then she got pregnant with her hubby ka child .. she had actually wanted that only .. her kid taking thei inheritance .. as she and her husband were poor
I also feel Pakhi will be made to sign the document.
Then n the last month of pregnancy she will run off with her mother in the greed to keep the baby. Thats why Sai kept 2 more names and told those names to Pakhi. So later she may keep that name and later Sai or virat may meet the kid with the same name.
Sai will also have savi maybe.
Too many guess we r doing when the writers themselves don't know what they will write next day.
