I know may think that shagun did great mother as she took care 0f pihu but was she really true mother.
If ishita wished she would had not let ruhi meet shagun after may incidents as she was also insecure many times but no she let her even when shagun left adi ruhi n went to Mumbai when she was with ashok n hurted them when adi accepted ishita as his mother then also she always maintained positivity about her.But was not being an true mother her responsibility to tell pig about her mother even if she is not alive according to them.Do this quality is of true mother .Can't she see the love the wish in eyes of Mr.n Mrs. Iyer to meet n love the last symbol of their daughter in this world.
I know ishita did injustice with pihu but that dent ears that she don't love her somewhere her love for ruhi n her guilt n most imp her fear that she is not n good mother which hunts her .All r at fault so no one can get the title of best mother or father in this show nor great grandmother or father.
They r angry with overs as they didn't break relation with mahi ka n Rome but did they ever think that already the overs have lost their one daughter n granddaughter how can they turn their face from their other daughter .N mi hi ka n romantic what the said at sound painful but is true too .
