Please Please Please don't show OVi pregnant and add to the mess. Ankita can be Pari , she does not have to be related to Archana to look like her , remember the theory there are 7 people in this world who look like each other ... people will accept that
Please don't add more dirt , there is nothing Pavitra in this Pavitra rishta . Arjun and Purvi will never be truly happy if this happens and if ARVI separate then no one be really happy it will be compromise all over again . I really do not want to see Ovi's daughter and Pari fight over same guys, very done with half brother/sisters falling for same person , there is nothing new. We just had a bad dose of this story line.
Please Please find a better way to leap .. if you really have to show Ovi's daughter then kill ARVI and Pari in some accident.
