I don't feel Kaka will become evil again. I think Kaka in black hoodie is s trap for Avni. In the BTS, there is a lady constable. I feel Avni's track will end by next week.
Next issue is the new person that wants to kill Shera.
From the way Goda is reacting, I feel this can 100% be Vikram. His mother was the Textile Minister and they were doing some illegal things on the side. I think its 100% possible for Vikram to team up with Kalyani's boss, the other Minister and they both did the moorthi smuggling.
