And it is completely understandable.
Believe it or not when one of our close family die , we try think we can undo it, it has not happened,or even try to wake up that person as though he is /she is sleeping... they are all crazy,but is so natural, and believe me it happens every time.....
Alekh might be affected by it,but Sadhana dying in front of him will have a bigger impact/shock than this.Infact I was hoping that he would breakdown when Mamaji had said all this, which would have been good thing if it happened.
For Mamaji, he did not mean what he said...it was just an emotional outburst!!
Eventually everyone(Mamji, Alekh,Raagini, Mamiji, maybe even Ranveer) will feel that they were responsible for Sadhana's death,and that is natural too...
A natural grieving process every human undergoes..
