I mean..yes Priyanka also didn't have much of a choice in the matter if she wanted to save herself...Ideally if she could've pitted ShaTina versus herself and Archana then, Tina would've gotten eliminated for sure.. Their group was in majority...Had she not struck an underhand deal with Shalin and allowed him to go and nominate Gautam, instead stuck to her core group and made sure ShaTina don't get a chance to nominate then it would've been possible.. They needed to work a permutation combination to make this (below) happen..
Saundarya-Tina
Gautam- Shalin
Archana- Priyanka
Priyanka- Archana
If she could trust her own standing in the game for a second and looked at the bigger picture..taken Archana into confidence then it was possible to break ShaTina and keep her group intact..Had she done that I would've hailed as the mastermind.. But in this particular task, Shalin made the most of the given situation which was not in his and Tina's favor.. now most likely Gautam or Saundarya are going to go..
