From week one Karan is nice to Pratik but Pratik has never ever tried to be close to him . he never talks to him or sits with him and he knows him before the show .
Outside his sister is playing very dirty game and targeting Karan only ..... she and his PR is targeting Karan from WEEK ONE when Karan didn't even do anything against him.
its very clear game plan of Pratik ....he knows Karan is strong and he wants main rivalry against Karan.
that's why he never tried to be close to karan , stays away from him , outside his sister is targeting KK from week one because it's PrePlanned strategy ....very clear planning for Karan vs Pratik so that Pratik can reach in final two .
reality shows mein toh PHD kar ke aaya hai afterall
