Yes bani will get backstabber thrice to make her move in right direction.
1) Jay - jo ki bahut aacha insaan acc 2 her
2) meera- maybe she is markaat
3) veer' mom - jo ki naagin hai aur uske acc sahi hongi as 4 her naag clan is saint .
Jay ki nataunki bahut dino tak nhi chalegi I guess it reach its end.
Bani will expose balwant's illegal business to veer , creating a rift between veer & balwant , she will only release veer's mom further creating problem b/w Veer & balwant , she will have full sympathy with veer's mom. Later when think will be really worsen b/w Veer & balwant, then she will get to know veer's mom is evil not saint.
Regarding meera she trust meera way to much , so if meera turned out markaat then it will be big betrayal .
As bani has a habit to judge people from face value .
