I dont find much difference between ishwari and Radha Rani.
Only difference is Radha Rani would confess her misdeed to herself when she is alone AND ishwari would hide all her misdeed in the name of 'Care, concern and struggle'.
I dont find her a perfect mom, partial mother can never be perfect.
Neha is a messed up girl all thanks to ishwari, but still ishwari cant see anything beyond Dev. Today, Dev has everything, whats the point of running behind him? She has contributed a lot for Dev, it's time to look after a child who was ignored.
I dont think Dev's love life should make any difference to her. She should look after Neha and encourage her (neha) to learn english. The way she struggled to give education to Dev, I dont see same enthusiasm in her when Neha is getting her education. All she is concern about poking her nose in life of Dev and eat chat masala food. Neha is totally right about her.
