What is the role of Arjun ?

Is it just me or anyone else think that Arjun has a ‘Dumb’ look ‘ Writers please make him little smarter. Even after knowing that someone might have intentionally hit her car, these two are not with her but busy talking away from their sister

His role is to eat our minds & screen space

No I don't want him as smart, I don't want him at all, send him on a honeymoon with Simone

He is there to make DJ and Simone break up after that nothing else

His role is to annoy the living hell out of us and he's making sure we don't miss Kartik with his creepy and clingy behaviour

His role is to badly crying and chipkofying with simone

Not only Arjun the other Mahajan gals are also disapeared from the show. Bilkul gayab. Yuvika had an accident and 1/2 of the house members are on vacation. Aise kaise chalega?
