The same Tulsi that she used to worship and adore, now she is taunting her and trying to threaten her in public and behind her back. Plus, why doesn't she use logic to think that Tulsi is stopping all this because of some reason that is unknown, rather than support the girl that isn't her own, Bhoomi, who got pregnant (even if it is fake) and had the audacity to say that at a party, where the media was present.
In my opinion, it is overdue for her to get a tight slap from Karan or Tulsi to remind who is the real boss of Shantiniketan and that she is living on the mercy of Tulsi, Ba and Karan. Otherwise, people like Tripti and Mohini will refer to her as the "other" woman!
