If Akheraj thinks that it will do good for his image if he sends that girl to SN to get educated he will send her there.
If he can be sickeningly sweet towards his daughter and her sausral he is quite capable of sending the girl to a better place for education.
Anandi was not bumped off along with Shiv for a reason. Had they wanted Nandini as a child bride they could have bumped off Anandi like they bumped off Shiv and then made her child bride.
The fact that Anandi is still around itself tells a story of it's own.
If so many assumptions and speculations are being made about a new entry even when makers have not made any announcements that he will be the man in the leads like the time they made during Shiv's entry why speculations Why speculations about how a mother and daughter get back together can't be made?
Also there have been many speculations about what the girl can get from her mother apart from education and guidance.CVs now are answering the question as to what the girl wants from her mother - answers to her questions and acceptance by her mother.
Don't think Anandi is being just kept in the show so that they can give a new saree every time she appears on the screen not to mention a new neck piece every now and then. So speculating about how and when she gets to see her daughter and how she punishes the man who kidnapped her daughter is not some thing which is not part of the story.
