There's just one punishment for her - Jagiya should leave her learning the badepapa truth and then she comes to know the guy and the famly anandi has married into.She should see how happy anandi is in her new life and how much her husband loves her.She should see that anandi is getting the love of not just the singhs but her new in-laws too which she never got in her life.
In short, I want her to see anandi happily married to a guy like shiv while her married life is totally devastated.Only then she can get a taste of what anandi went through.
She hates Anandi more than anything, so Living well is the greatest Punishment that Anandi can give Gauri.
