I saw a segment on SBAS where it was shown that Sahiba will become Jethani while Seerat Will become Devrani. And i guess Garry didn't tell her that he is younger to Angad that made impossible for Jasleen, Garry and Seerat to take any role in become Bada beta or Badi Bahu...
These people are so dumb that they forget that Sahiba as Jethani will have more responsibilities and will ace this ... While Seerat who can't take responsibility of her own action who will make her or give her responsibility...
