Gauhar never had any intention to leave. She overestimated her importance and felt by screaming and fainting spells she can convince BB to repeal their decision. But BB kept quiet even in confession room and didn't bother to stop her from leaving 😆. On the other hand Kamya and Pratyusha were persuaded by BB to reconsider their decision. BB could see well in advance that Gauhar will return back in a day once she is assured of her importance/narcissism 😉.
