And I have a feeling that the rowdy family might be related to Vishwa, since they spoke in Telugu...
Priya, it was shown already that they were related. Few weeks ago Vishwa gave ganja(in the name of sweets) to Padma & Mohan and made them deliver to that rowdy family, that's how the rowdy family got introduced. i think Vishwa's wife and Shyamala's dad r brother/sister, i don't remember the relationship correctly.
