I think it might not be related to karan at all. I think it cones out because of jealousy/insecurity from Shamita. Whatever we say it is true shamita is big name compare to tejaswi. I remember when vidhi and donal was out, she was not upset. Did so bad acting given that vidhi was good to her. She is just having insecurity from every girl in the big boss house who might be successful or competitive to her.
