He is stubborn, egotistical, and close minded. His behavior on tonight's episode was extremely concerning, and based on the promo we saw for tomorrow (where Karan talks to him), he seems to not have cooled down at all. Sad thing is - BB is playing that cringey Sarkar wala dialogue on the promo as if to portray Jay as an anti hero. But it doesn't suit him. He is just looking like an a-hole. Plus his image (especially as a host) is of a nice, happy-go-lucky, goofy guy. If BB is going to keep encouraging this behavior for the sake of creating continuous conflict, then this might be detrimental to Jay's longterm image.
Despite repeatedly saying no for years and years, Jay finally agreed to be on this season at the last moment, that also because the channel (who were counting on a last minute partnership with Rhea Chakraborty) made him an offer he simply could not refuse. Even though I'm sure this is his biggest paycheck ever, I would be very careful if I was Jay. Better to lose the show and gain respect than to reach far but lose hard-earned industry goodwill.
