Rakhi's words about Pramod seemed to indicate that he was a lot like Toshu: a gold digger who was delighted to be a Ghar jamai and she herself used to be a friendly person like Kinjal before Pramod cheated on her. She said that she became Naagin around that time. BTW we never saw much of Pramod to see him as a decent person but Rakhi is thousand times better person than BB, V, Kavya ,MAAya , Shahs, Kapadias and AnupaMAA. Compared to other ''vamps from modern world'', she was decent, classy, transparent, straightforward, honest and motherly. Even Kinjal said that her time with RD on Diwali was peaceful.
