Answer : They know he is most popular so they are all jealous and trying their level best to show him in bad light and bring him down.
Even his so called buddies...PP have realized the power of Gautam. Every house mate in some way or other connects his/her name with Gautam so they stay in the limelight. Sonali tired to romance him, Karishma always trying to vilify him, Diandra hates him, Arya is looking for excuses to fight with him, Upen wants to throw him out, Ali is bitching about him, Nigar has problem with his dress sense, Puneet uses him and Pritam and Praneet are jealous... Dimpy and Renee have seen the viewer's reactions so are keeping Gautam in their good books.
So in all without Gautam, BB8 will not be interesting.
Thanks Gautam for entertaining us...keep doing whatever u want! (Salman style)👏
