When Satyaki says his name, Vidya replies, "Satyaki - Arjun ka sarthi (Satyaki - Arjun's charioteer)." However in the epic Mahabharata, Satyaki is Krishna's charioteer and Sri Krishna is Arjun's charioteer.
Just after Vidya Bagchi takes the key of room 15 from the manager of Monalisa Guest House, she passes 2/3 people sitting in a common room. The man with yellow-collared t-shirt has sunglasses hanging from his t-shirt which disappear and reappear between shots.
At her first visit to the Police station,Vidya Bagchi avoids signing the Missing Person Report she just filed. But according to the Law, one who is filing the missing person report/FIR must sign the report else the report is of no use.
