The rule says the judges has the power to save one contestant after he/she has been evicted, but the judges are yet to use the power to save any contestant.
When Efezino's name was anounced as the contestant to leave the show, she immediately went on her kneels begging the judge to save her, but Femi Kuti said she was the weakest link of the competition and saving her would make no sense.
Can you plead to be returned back into the house if you are in her shoes even if you are not the weakest link..?
