What would Trilok gain by buying AN which is in shambles now and nomore inhabited by anyone any longer though? Not that I think AS &Co having any interest in it now that they live in a much bigger house would make any sense either... the only one who would make sense having any interest in that place is Kalyani, as she'd have many good memories there, but as y'all said, it's a mystery how she even managed to complete her education and become DM without any family backup and no money.
Unless they introduce someone going forward who found and rescued her that had money and helped her with it.
Maybe someone old who, before going, left her his/her money and she made good use of it, and will use that money to buy AN now? A girl can dream, right?
I wanna see Kalyani bring these Deshmukhs to their knees for their treatment of Anu and Swara!
