The reason it hasn't happened before is because of the unfairness factor. If BB chooses to defy the past norms, then so be it. But I think it would be unfair for a contestant to spend time, even if it was little, outside the house and come back in and win it. That defeats the WHOLE purpose of the Bigg Boss game of being locked up and shut out from the world continuously. The little break a contestant would've gotten provides an advantage to the said contestant. Just my opinion.
