Its really sad to see that,even today,u r not able to differentiate between reel characters n real.as far as i know,tanisha was never had any crush on ur so called baby,so u r wrong in this.
secondly Riah might have failed as a father,even PRB,but at least they both r kind enough to acceppt other kids as theirs,like prerna acceppted vish,tushki,kuki.rish acceppted sneha n prem2,which is much better rather than taking 8 years time to come to know that sneha is his kid only,n what more,he trusts DNA report more than anything else,which is much more disgusting than anything else.
he was such a father that,becoz of his ego,he lost prem 1,even when he was born,he was not aware that,prem1 is his kid only.all his life,he was not able to call his own kids as his in front of world.
