Exactly!! Shalin HATES Priyanka so much coz she foiled his whole plan.. Also she called him out for all the bullshit he spews..so now after being in gaslighter Shalin's company, Tina, for the first time has a genuine friend in the house who defends her as well.
Initially I was doubtful about Tina and Priyanka's friendship because Tina had always shown a strong inclination to become mandli chamchi for her game's sake, but it can be seen their friendship is genuine. Priyanka defended Tina in front of Salman as well.
Tina was actually quite good in initial week...with a bit of sass and a smile here and there. Then she got into Shalin-Sumbul muck and went into a different tangent entirely. She should've left Shalin for Sumbul only..All she've got from Shalin's track is humilation. I feel Shalin played with her mentally like a puppet. He knew what he was doing.
