Big Brother Brasil 13

Cast

Regional applications were due from March 30, 2012 to July 30, 2012. Regional auditions were held in nine different cities over Brazil.

National applications started on July 31, 2012 until October 31, 2012. The semi-finalist interviews were held in November 2012 and the final casting interviews took place early in December 2012.

Glass House

On January 5, 2013, six housemates were locked for seven days in a Glass House located at Santana Parque Shopping in São Paulo. It was announced that Marcello received the most votes among the males, while Kamilla received the most votes among the females. Both therefore left the Glass House on January 11, 2013, and entered the main house on January 14, 2013.

Veterans vs. Newbies

For the first Head of Household (HoH) competition of the season, Big Brother divided the housemates into two teams: the Veterans and the Newbies. When a housemate from a team won the role of the Head of Household, then all members of that team were automatically immune from eviction.

Bambam walks away

On January 12, 2013, Big Brother Brasil 1 winner and current HoH at the time, Bambam, walked out of the game. At the live show on the same day, the Veterans decided as a group that Fani would be the new HoH. Following that, Yuri Fernandes from Big Brother Brasil 12 entered the house as Bambam's replacement.

Power of No

Introduced in previous season, the Power of No still gives the Monday Game Night winner, the opportunity to disqualify a number of people (previously determined by the producers) from competing in the Head of Household competition alongside the previous HoH. This season however, started on week 4, the vetoed housemates could remove themselves from the block and compete for HoH if they win the Save Me Challenge, which takes place on Wednesdays nights.

Big Brother Back and Forth

On week 3, after a fake Head of Household competition, housemates were told there's gonna be a surprise eviction. The housemate with the most votes would be immediately evicted on Saturday, January 26.

In reality, the public voted for which housemate between the two fake nominees Anamara and Marcello, would enter the Secret Room and be able to watch their fellow housemates on a television screen, and then return to the house on Sunday, as the real HoH of the week. Anamara won with 57% and was fake evicted on day 19, but returned the following day during the real live nominations.

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 (whom he had a brief showmance) that he will wait for her outside, which she replied stating "I loved it all! I will never ever forget it. Not ever".
