They learn that Naina had called a suicide helpline several times, but the calls were actually made by Sheetal, a friend of Naina who was hired by Radha, a volunteer at the helpline. Radha reveals that she was Vishesh's lover and she wanted to take revenge on Aman for killing him and their unborn child. She also killed Sheetal to eliminate any evidence.
