When Meethi asked Vishnu about his family in day before yesterday's episode, there was some ominous music in the background and he stayed quiet for a few moments before saying that his father died in a tragic incident when he was 8 years old and his mother couldn't take the trauma of his father's demise.
If he was 8 at the time Icha killed Avinash, it's round about the same age as Kanha... and he MAY just turn out to be Avinash's son trying to take revenge.
CVs have kept this option 'open' by giving vague details about him... like why doesn't Icha remember him from Satara jail? And if they had to introduce a character from Icha's teaching days in the jail, why didn't they show a couple of incidents of Vishnu as a boy?
There's something fishy and I'm sure when CVs feel the TRPs are running low, they will play Vishnu's card and turn him negative to gain interest!!!!!!!!!
I SINCERELY hope this doesn't happen though!!!!!!
