@Rani and others - I completely agree with you!
While Sulekha has taken the responsibility of Anand D and taken care of him while Siddhi was in the jail, it is not because she of her selflessness but because of her son, Abhay
Sulekha has presumed a lot of things, based on hearsay. If she was such a well wisher of Siddhi, she could have tried to trace Richa and Bada Anand. She had the time, money and other resources to find out the exact truth. Instead she took the easier and more selfish route of keeping Anand D with her, so that the kid could act as a balm for Abhay's sadness...
I am sure, we will see Sulekha put pressure on Siddhi in the near future to marry Abhay!
It has been Sulekha's plan all along!
