Beyond all the drama, Bigg Boss was just a game. A reality show which had to be played to be won. Though the contestants forgot this at most times, the show reminded them. Eliminations and in-show games brought out the competitive spirit and the determination to win from the contestants.
Although they shared love and never wanted to see another go down, the contestants had to ensure their own place on the show, even it meant the outing of others.
Lesson: Have goals and reach to the top. Even if you don't win, keep trying.
