He's doing only time pass because Bbhse after 3 and a half month got boring and contestants became less,there wasn't much tasks to be done..so only this angle was left to fight boredom.Stan couldn't stand a loud irritating bossy woman like PCC in his life.He's calm and sorted not desperate or hyper like her.
Stan ne priyanka ko ullu banaya,he went on to win the trophy while she was left with empty , fake bubble of being a BB winner. She did not even reach top 2 because she got obsessed with Stan's and criticising Shalin every secothe last 4Maybe it was his game plan to distract priyanka from her goals by faking an interest in her after 3 months.
