I feel that the only solution to this problem with VIrani;s will be solved by Payal Mehra...I think they will get her back some time very soon in the next few episodes.
After Ansh's murder they just did not show Gujral at all for many episodes..people started wondering how come he is so silent when his son has died....now its all him in the serial...similarly I think they wil bring Payal Mehra also back shortly.
