Appeared and Disappeared
On February 14, 2013, Big Brother revealed to the public that the first housemate to go into the pantry on Saturday, February 16, would be secretly taken out of the house for a day at a spa. Around 10:00am, Kamilla was the first to be entered the pantry and 'disappeared' from the house, leaving the remaining housemates worried about her whereabouts. At 7:00pm, producers told the housemates to pack Kamilla's belongings to lead them thinking she was out of the game. Around 11:30pm, Kamilla finally returned to the house during the Disco party and then, explained to her shocked fellow housemates what happened to her.Running Against Time
On February 21, 2013, Big Brother revealed to the public that the Big Phone would rang on Friday, February 22 at 6:00am. Whoever answered would be automatically nominated for eviction. At 12:00pm, a giant stopwatch counting down 20 hours would be placed in the garden. On top of it there would be a button. The first housemate who pressed the button would stop the countdown and win a surprise immunity. However, if the housemate who was previously nominated by the Big Phone pressed the button, this housemate would win the immunity and choose his replacement nominee. At 6:00am, Eliéser answered the Big Phone and was automatically nominated. At 12:03pm, Fernanda pressed the buttom and stopped the countdown but she was only informed about her immunity during the live nominations on February 24, 2013.The Mystery Box
On March 7, 2013, Big Brother announced the first twist of week 9. On Friday, March 8, at 12:00pm, a mystery box would be placed in the garden. To open the mystery box, the housemates would have to find the right key, between thirty hidden keys scattered throughout the outdoor area of the house. The first housemate who opened the box would win a R$10.000 cash prize, choose one housemate to be automatically nominated for eviction and veto other two housemates from the Power of Immunity competition.The mystery box ended up being placed in the house only at 2:30pm due this week's HoH endurance competition overrun. Andressa and Kamilla found the box in the garden around 3:30pm. Andressa beat Kamilla and found right key first, winning the challenge.
It's Not What It Seems
Also on March 7, Big Brother revealed the second twist of week 9: new housemate Miguel, supposedly from Gran Hermano Argentina, entered the house on March 8. However, in reality, he was an actor working for Big Brother. His mission was told the housemates that he would choose one of them to win immunity and spend a week in the Argentinian house. The truth was partly revealed on March 10, during the live nominations. Host Pedro Bial only told the housemates that there was no immunity up for grabs and continued to hide the fact that Miguel was an actor and not a Gran Hermano housemate.After that, Miguel left the house promising to Fani that he will wait for her outside, which she replied stating "I loved it all! I will never ever forget it. Not ever".
