Avika is the cowd puller for SSK and if she turns negative, no 1 will watch the show. Also simar is extremely selfish and does not seem like a nice lady as you pointed out. She doubted her own sister, especially a sister who has done so much for her. You had mentioned in another post that the younger one always turns negative, what kind of logic is that? If you remember Bidaai Ragini was the older sister and she was the 1 who turned negative.
