Question: naagin who is the 5th killer?
Answer: In the past few weeks, Yamini (Sudha Chandran) has been trying to win the trust of both the Naagins. While she's managed to convince Shivanya (Mouni Roy) that Ritik's (Arjun Bijlani) father Sangram Singh (Arjun Bijlani) is the fifth killer of her parents, she has also been coaxing Sesha to marry her son.
