On the BBNaija gameshow, Biggie asked Maria just moments after the debate competition on August 13th to bring the rule book from the house to the arena. Then she was asked to read out a particular page that applied to the HOH rule which she did.

She, Liquorose and Peace were then banned from he HOH Room for two weeks.
