Friends Amma is playing her cards very effectively,she is making Krishna believe that now she really cares for prats.She is very desperate to regain her position as queen of TN and also wants Krishna and SS on her side by showing love for prats she can easily do this.The other thing is she wants to create rift between Krishna and Pratigya.Amma knows very well Krishna loves Pratigya more than his own life so she is using his love for Pratigya as her tool in playing this game.As far as Krishna is concerned he will believe his Amma this time bcoz for her fake love for Pratigya.SS will support Pratigya for sure as he is only one who knows and understand Krishna and his love for Pratigya more than anyone else.Aur waise bhi galti insaan se hi hoti hain Krishna se bhi yeh galti hogi Apni amma par trust karega Pratigya par nahin.Amma is going to ruin his own innocent son life for her selfish motive.
