It is not like Anandi has always been cool and calm.
There are many instances where she got angry with her family members.Like when DS went ahead and proposed to Shiv on behalf of her then when Jagya went away soon after their marriage and the family hid the truth from her are two such instances.She even got angry with Shiv when he agreed to marry her because she thought he agreed to marry her out of kindness.
Even then her reactions were criticised as being OTT.
Outburst did not happen straight away.She inquired after everybody and saw that they are up and about and trying to put this behind and get on with their lives.
This happened only after she asked about Ganga and found that she left.
She also reacted to Sumi the same way Jagya and Bhairon did when she heard what Sumi had to say.
She was upset with J and DS because they made themselves responsible to Ganga's well being and they let this happen.Agreed J was not there when Ganga left but DS should have convinced her to stay till it is morning.
It may have been Ganga's decision to leave but DS should have convinced her to stay till morning and made arrangements for her to stay at some place else.Because she has taken it upon herself to look after Ganga.
It is not about blind support to Anandi and Ganga.
I do feel Sumi's line of thinking is not wrong but her taking out her frustrations on Ganga was wrong.
DS and J have a right to take on Ganga and help her stand upon her own two feet and protect her from her menacing husband.But if they have taken the responsibility looking after they should have ensured the safety of their own family too.They failed in that.
Ganga has decided to leave and they are fully right in respecting her decision to leave.But while respecting her decision DS could have convinced Ganga to stay on till morning and found her place to stay still she finds her own feet.
Anandi was right in her outburst against DS and J because they were the ones who brought Ganga to Haweli and took the responsibility for her safety and well being and they failed in that.Jagya is not at fault but at this given point she does not know that J did not have any hand in Ganga's departure.
Allowing a helpless woman that too with a small child leave their home in the middle of the night seems to be a very callous thing to do.So Anandi was right in her outburst.
