I was rewatching old episode balwant said bani's mom too was a naagin who died in d plane crash .
I don't know why but I feel bani may have a real sister who too would be naagin .
Actually it's look so weird that veer cheel has full gang but adi naagin is fighting alone no one is there from her clan to help her , bas ek backstabber naag is there to create problems for her. Infact cheel god markat ka bhi apna alag gang hai.
Naag clan chodo , koi dhaang ke guru bhi nhi hai , ek the jisse pagal jay ne maar diya , unki wife ko kuch nhi pata.
