BB first made whole house against ankit by taunting him endlessly .BB literally called contestants in CF and told them to nominate ankit . So when Ankit came in nominations BB played his game and kept voting lines closed . They gave priyanka an opportunity to save Ankit . Definitely she would save Ankit and this will give HMs a reason to target both priyanka and Ankit. BB knows Ankit can't be evicted by audience votes so they used this opportunity to target priyanka and also let her save him so that contestant opinion about Ankit doesn't change and would target him in future weeks aswell considering him a weak contestant. Makers can't evict Ankit as he has fans and has enough of hype but BB doesn't want HM to get any about this so they keep taunting Ankit taaki gharwale usse strong contestant naa maane .
