I think the next person in line who will have a problem with all this is Dulari...the way she was reacting seeing ViDha together clearly says.
Than Vips has to deal with his own evil Dada and mom who are planning to ruin his life, only becoz they think it will distract him from Dhaani and Ashram. Instead this action of theirs will push Vips to take a final decision ultimately and in this process Tanya will get badly hurt. If Vips would know abt the engagement, at least he would have the time to clear the air with Tanya nd tell her he doesnt have feelings for her...Gosh...I am scared thinking what will happen with Dhaani if someone sees ViDha together in the mandir
