# Big Brother 19 (American season)

Big Brother 19 is the nineteenth season of the American reality television series Big Brother. The season premiered on June 28, 2017, with a 2-hour season premiere, broadcast on CBS in the United States and Global in Canada, and ended with a 2-hour season finale on September 20, 2017, after 92 days of competition. Julie Chen returned as host. On September 20, 2017, Josh Martinez was crowned the winner defeating season 18 runner-up Paul Abrahamian in a 5-4 jury vote, earning the latter the distinction of being the first person to receive the runner-up prize two years consecutively. Cody Nickson was voted as the season's America's Favorite HouseGuest.

## Format

Big Brother follows a group of contestants, known as HouseGuests, who live inside a custom-built house outfitted with cameras and microphones recording their every move 24 hours a day. The HouseGuests are sequestered with no contact with the outside world. During their stay, the HouseGuests share their thoughts on their day-to-day lives inside the house in a private room known as the Diary Room. Each week, the HouseGuests compete in competitions in order to win power and safety inside the house. At the start of each week, the HouseGuests compete in a Head of Household (abbreviated as "HOH") competition. The winner of the HoH competition is immune from eviction and selects two HouseGuests to be nominated for eviction. Six HouseGuests are then selected to compete in the Power of Veto (abbreviated as "PoV") competition: the reigning HoH, the nominees, and three other HouseGuests chosen by random draw. The winner of the PoV competition has the right to either revoke the nomination of one of the nominated HouseGuests or leave them as is. If the veto winner uses this power, the HoH must immediately nominate another HouseGuest for eviction. The PoV winner is also immune from being named as the replacement nominee. On eviction night, all HouseGuests vote to evict one of the nominees, though the Head of Household and the nominees are not allowed to vote. This vote is conducted in the privacy of the Diary Room. In the event of a tie, the Head of Household casts the tie-breaking vote. The nominee with the most votes is evicted from the house. The last nine evicted HouseGuests comprise the Jury and are sequestered in a separate location following their eviction and ultimately decide the winner of the season. The Jury is only allowed to see the competitions and ceremonies that include all of the remaining HouseGuests; they are not shown any interviews or other footage that might include strategy or details regarding nominations. The viewing public is able to award an additional prize of $25,000 by choosing "America's Favorite HouseGuest". All evicted HouseGuests are eligible to win this award except for those who either voluntarily leave or are forcibly removed for rule violations.

## HouseGuests

The House Guests were announced on Monday, June 19 at 6 AM PDT through the CBS website. Interviews with the cast were released at 8 AM PDT on CBS All Access. The cast includes season 18 HouseGuest Paul Abrahamian.

| On Day 1, 16 new HouseGuests entered the newest rendition of the Big Brother House. After getting settled in and introductions were done, they were then informed by series host Julie Chen that the theme for this season is "Summer of Temptation", where they would face various offers during the game that would offer them prizes and unique game-changing advantages throughout the season. However, every temptation that was accepted in the House would have a consequence that would affect at least one of the other HouseGuests. They began the summer inside the Garden of Temptation, the first competition of the season. Temptation Competition ("Garden of Temptation"): The HouseGuests, while sequestered in 16 separate pods, were given the offer of $25,000. A flower was placed in front of the pods and the first HouseGuest to press their button when the flower lit up green would win the money. The identity of the person who pressed the button to accept the money would remain anonymous, however their actions would unleash the first twist of the season. Kevin accepted the offer, but in doing so it required him to throw the first Head of Household competition as he was now ineligible to win it. As another consequence for Kevin pressing the button, Paul from Big Brother 18 re-entered the House as the seventeenth HouseGuest. However, it was revealed by Chen that he would be swapping spots with one of the new HouseGuests that would be evicted the same night in a first-ever "BB Swap". Paul was given the task to select eight HouseGuests to receive a "friendship" bracelet. Any HouseGuest who received a "friendship" bracelet would be immune from eviction. He gave bracelets to Kevin, Raven, Dominique, Mark, Jason, Jessica, Ramses, and Elena. Safety Competition ("Tempted by the Fruit"): The remaining eight HouseGuests battled for their lives in the Tempted by the Fruit competition. In this competition, HouseGuests had to stand on a trapeze bar while holding on to a rope. If a HouseGuest fell off, they had to select an apple from a serpent. Four apples contained safety, while three apples were "poisonous". As the competition continued, Julie would give them clues guiding them to the four safe apples. The last HouseGuest standing would guarantee his or her safety from the eviction, and the three HouseGuests with poisonous apples would be nominated for the first eviction. Cody was the winner; Christmas, Cameron, and Jillian had the poisoned apples and were put on the block. The nominees were then presented with their own temptation. Each nominee had the power to decide how their fate would ultimately be determined. They would each decide to either face an eviction vote or compete in an eviction competition, with the top 2 finishers guaranteed safety and the third-place finisher automatically evicted. By a vote of 2-1, they decided to face an eviction vote, with Cameron voting for an eviction competition. On Day 1, Cameron was evicted by an 8-3-2 vote, with Cody, Mark, and Matt voting to evict Jillian, and Josh and Jason voting to evict Christmas. Julie then revealed the next twist to the viewers. Each week, America would vote to select one HouseGuest to enter the "Den of Temptation." Inside the Den, they would be offered a temptation. A HouseGuest is only able to be selected once throughout the entire season. However, every temptation will come with a consequence. |||||||

| Following Cameron's eviction: Head of Household ("Hangs in the Balance"): Big Brother 18 winner Nicole hosted the HouseGuests in the Hangs in the Balance Head of Household competition. In this competition, HouseGuests were divided into four same-gender teams. One at a time, HouseGuests had to swing across their ropes and grab a rotten apple and then return it to their station. However, they were all tempted by a golden apple: the first HouseGuest to return a golden apple would earn safety for the week, but would also eliminate their entire team from the competition. Josh took the temptation, eliminating his team. The first two teams to retrieve eight apples would advance to the second round of the competition. The pink team and the blue team were the winners, who then went head-to-head to balance seven apples on a tree. However, only one person per team could compete. The first HouseGuest to successfully balance their apples would be the first Head of Household. Cody was the winner. On Day 5, Cody nominated Jillian and Megan for eviction. As Head of Household, Cody was required to name five Have-Nots for the week. He selected Megan, Josh, Jillian, Paul, and Ramses. However, the Have-Nots were offered a temptation. On the wall of the Have-Not room, there were two available spikes. Inside one spike is a Have-Not Escape which would allow its holder to leave the Have-Not Room and become a Have for the week. However, the other held a Have-Not Extension, making the holder a Have-Not for an extra week. One Have-Not per week could go to the Diary Room to claim the key to unlock a spike. On Day 8, Megan withdrew from the house following an argument with numerous HouseGuests over an alleged racial slur. |||||||

| Following Megan's departure: Paul took the Have-Not temptation and successfully claimed the Have-Not Escape. The HouseGuests learned of the Den of Temptation. Paul was given the offer of the Pendant of Protection, which would give him immunity for the next three evictions. By accepting the offer, another HouseGuest would be cursed. Whichever HouseGuest was represented by the chosen bottle would be the consequence recipient. On Day 9, Cody nominated Alex to replace Megan on the block alongside Jillian. As consequence for Paul accepting the Pendant, one HouseGuest was "bitten" by a snake inside the Den. The HouseGuest bitten will be cursed and be given further instructions by Big Brother. Ramses was bitten and learned that he must place himself on the block as a third nominee within one of the next three nomination ceremonies. |||||||

| Power of Veto ("Fin to Win"): On Day 9, Cody, Alex, and Jillian, alongside Matt, Raven, and Jason, scrapped in the Fin to Win Power of Veto competition, which was hosted by Kevin. In this competition, HouseGuests had to pull the plug on their water timer, causing it to drain. They had to then search the water for starfish and put them on their stacking shelf one at a time. If their water began to run low, they could collect water from the ocean to put in their timer. Once a HouseGuest's water timer was empty, their starfish were locked in. However, the players were also offered a temptation. The first HouseGuest to find a gold starfish and place it on their shelf would earn a Never-Not pass, meaning they cannot be a Have-Not for the rest of the season. However, they would eliminate themselves from the competition. Raven took the temptation. The HouseGuest with the most starfish stacked on their shelf after their water had drained would win the Power of Veto. Alex won the Power of Veto. On Day 11, Alex took herself off the block, and Cody attempted to nominate Paul, who was immune thanks to the Pendant of Protection. This led Cody to nominate Christmas as the third replacement nominee. |||||||

The first HouseGuest to land a ball in the center heart would be the new Head of Household. Paul was the winner. Cody, Jason, Jessica, and Matt became the Have-Nots for the week. On Day 17, Christmas was tempted with the "Ring of Replacement" inside the Den. If she accepts this temptation, she can replace a randomly drawn player in any Veto competition this season. She accepted the temptation. She was then required to select three HouseGuests for the curse, and these three will be the only people Christmas has the option to replace. She selected Cody, Jessica, and Jason. On Day 17, Paul nominated Alex and Josh for eviction, with the plan to backdoor Cody, while Ramses revealed his curse and named himself as a third nominee.

## Twists

Changes to the main format known as twists occur during the course of the season that will impact the lives of the House Guests during their time in the House. The twists for this season center around the theme of temptation where the House Guests will be tempted with money, power or safety during their stay. Each temptation however will come with a consequence that will impact the entire House. The overall main twist is being billed by the program as "The Summer of Temptation" for this reason.

### Standard Temptations

During the season premiere the House Guests were presented with the first temptation of the season, in which each new House Guest had a chance to secretly win $25,000. Kevin Schlehuber was the quickest to claim the monetary prize, resulting in two different consequences. The first consequence was personal: Kevin was not allowed to win the first Head of Household competition; to keep his winning a secret, he had to throw (intentionally lose) the competition.
The second consequence unleashed a major twist on the House called the "BB Swap." This resulted in Paul Abrahamian, runner-up from the previous season, entering the House as a full House Guest eligible to win by taking the place of an original House Guest. Shortly after entering Paul was given nine friendship bracelets which gave immunity from the first eviction. Paul was instructed to take one for themselves and give the remaining eight friendship bracelets to the House Guests that did a good job tempting them. The remaining eight House Guests took part in a competition for safety which resulted in Cameron, Christmas, and Jillian being nominated for eviction. The three nominees were given the power to choose how their fate would be determined. The nominees had a choice of a competition or a house eviction vote. Only Cameron chose to have a competition; shortly after, the House Guests voted to evict Cameron from the House.
The following temptation would be during the second Week 1 HOH competition. During the competition, a golden apple appeared that would guarantee safety for the person who grabbed it, but would eliminate the team from the competition. Josh took the temptation, eliminating his team from the HOH competition. In the Week 1 Power of Veto competition, the first House Guest to find a gold starfish and place it on their shelf would earn a Never-Not pass, meaning they cannot be a Have-Not for the rest of the season with the consequence of eliminating themselves from the competition. Raven took the temptation.

### Battle Back Showdown

Instead of permanent eviction, the first four evicted House Guests received a chance to return to the game. Unlike last season, this showdown was done in playoff style. They will participate in a 3-Round-Battle in order to gain their spot back in the house. The first competition "Maze Race" will eliminate the bottom two finishers, permanently eliminating them from the game. Dominique and Jillian lost the competition to Cody and Cameron respectively; The second Competition between Cody and Cameron determined which of the first four evicted House Guests will be the last one standing and battle one of the House Guests in the house for a chance to get back to the house. If the evicted House Guest wins against the current House Guest, the remaining evictee will have a second chance to re-enter the house. However, if the current House Guest defeats the returning evictee, no one will be returning to the house effectively blocking the Battle Back. The House Guests unanimously voted to choose Paul to battle Cody in the final competition. Cody chose "Maze Race" as the final competition. Cody won and re-entered the house on Day 30. All three duels aired in a special episode on July 21.
| Round | Winner(s) | Loser(s) |
| 1 | Cody, Cameron | Dominique, Jillian |
| 2 | Cody | Cameron |
| 3 | Cody | Paul |

### Den of Temptation

During the first three weeks of the season, the viewing public voted for a HouseGuest to secretly enter a room called the Den of Temptation. The temptation inside could provide an advantage in the game, but also came with a consequence. The public's chosen HouseGuest could choose to accept the temptation or reject it completely. Each HouseGuest could only be chosen to enter the Den once during their time in the House.
| No. | Temptation | Consequence | HouseGuest | Consequence Recipient | Result |
| 1 | Pendant of Protection The HouseGuest will be immune from the next three evictions. | The HouseGuest must pick a poison that is tied to another HouseGuest. The HouseGuest whose poison was chosen is now "cursed" and must volunteer to be a third nominee for eviction once over the next three weeks. | Paul | Ramses | Accepted |
| 2 | Ring of Replacement The HouseGuest will have the power to swap with one of the randomly drawn players in the Power of Veto competition and take their place. | The HouseGuest must choose three HouseGuests to wear "Ve-Toad" costumes for the rest of the week. | Christmas | Cody, Jason, Jessica | Accepted |
| 3 | Halting Hex The HouseGuest will have the power to cancel one of the next four evictions. | The Temptation Competition will be unleashed over the next three weeks. | Jessica | All HouseGuests | Accepted |

### Temptation Competition

Due to Jessica accepting the final temptation, the Temptation Competition was unleashed over the next three weeks. Prior to nominations, HouseGuests (except for the current Head of Household) could decide if they wanted to compete in this competition or not. The winner of the Temptation Competition would receive immunity for the week; however, the HouseGuest who finished last in the competition would automatically become a 3rd nominee.
| Week | Competitors | Winner | Loser |
| 5 | Alex, Jason, Mark, Matt | Mark | Jason |
| 6 | Alex, Cody, Elena, Jason, Jessica, Kevin, Mark, Matt, Paul, Raven | Cody | Jessica |
| 7 | Cody, Elena, Jason, Josh, Kevin, Mark, Matt, Paul, Raven | Mark | Matt |

### Tree of Temptation

After Cody and Elena's eviction, Julie revealed a new twist into the game, unleashing five possible temptations for HouseGuests to select over the next three weeks. These temptations included powers and punishments. When the apple tree turned red, the first HouseGuest to enter the Diary Room got to claim a temptation from the apple tree. Once a HouseGuest claimed an apple, they were not eligible for another temptation.
The 5 available temptations were Save a Friend, Can't Play in Next HOH, Second Veto, Bounty on Your Head, and Eliminate two Eviction Votes.
| Week | Name | Description | Picker | Result |
| 8 | Save a Friend | The holder can award immunity to another HouseGuest for the week. | Mark | Paul |
| 9 | None | None | None | None |
| 10 | None | None | None | None |
* ↑ No one decided to choose an apple temptation.

## Production
### Development

Big Brother 19 was produced by Endemol Shine North America and Fly on the Wall Entertainment with Allison Grodner and Rich Meehan returning as executive producers. This season of the program has been confirmed since August 10, 2016 as part of a multi season renewal between Endemol Shine North America and CBS which also includes its twentieth season scheduled for the summer of 2018. Julie Chen returned as the host of the series.

### Broadcasts

The main television coverage of the season was screened on CBS beginning June 28, 2017 with a two-hour season premiere. This season featured no changes to the schedule that was used in the previous edition, with episodes airing on Wednesday, Thursday, and Sunday each week. The weekly Thursday episode, which airs at 6 PM. PDT, featured the live eviction and subsequent Head of Household competition taking place. During the live eviction, the show will be hosted by Julie Chen. The weekly Sunday episode, which airs at 5 PM PDT, features the nomination ceremony, as well as some highlights from the previous days. The weekly Wednesday episode, which also airs at 5 PM PDT, features the Power of Veto competition and the Power of Veto ceremony, along with more highlights of recent events in the House. The live Internet feeds which have been a staple of the program since its first season will return as part of CBS All Access. Alongside the weekly shows on CBS spin-off series Big Brother: After Dark will return on Pop for its twelfth season. The show serves as a live feed into the House, and is edited for profanity, nudity, slanderous statements and music copyrights.
A special episode was aired on July 21 to show the "Battle Back Showdown" where one of the 4 first evicted House Guests competed to re-enter the Big Brother House.

### Prizes

The House Guests will be competing for the main prize of $500,000. Cash prizes of varying amounts may be offered as "temptations" over the course of the season. Kevin Schlehuber was awarded $25,000 on the premiere episode. The second cash temptation of the season was also claimed by Kevin; this time, it was a smaller sum of $27.
The fan-favorite poll, America's Favorite HouseGuest was awarded Cody Nickson with $25,000 during the finale. While HouseGuests are eligible to win the award, only Megan Lowder was not eligible due to her withdrawal on Day 8.

## Reception
### Critical response

Paul Abrahamian received criticism for their controversial mimicking of another HouseGuest. In Week 3, they targeted Dominique Cooper for eviction and decided to apply black facial cosmetics and clothing that resembled the skin of a snake, in regards to a metaphor that she had used in an effort to expose their strategy to other HouseGuests. Given that Cooper is African American, Abrahamian's actions were deemed racist when they referred to the cosmetics as "blackface."
Viewers also debated on Abrahamian's alleged bullying tactics in which they encouraged other HouseGuests to antagonize "outcasts" in the House, especially showmance allies Jessica Graf and Cody Nickson. Some notable incidents include Christmas Abbott propagating aspersions on Nickson's military service, and Alex Ow and Raven Walton engaging in verbal arguments with Graf. Likewise, a physical confrontation nearly transpired between Josh Martinez and Mark Jansen (who defended Nickson), as Martinez was agitating Jansen by banging pots and pans in his face. Another fistfight almost ensued between Abrahamian and Nickson after Abrahamian silenced Graf in front of Nickson in the HoH Room. Abrahamian, who was HoH at that time, bypassed the confrontation instead by sending Nickson out of the room while screaming condescensions at him.
Some fans also perceived Megan Lowder's voluntary exit on Day 8 as a result of bullying. During a backyard conversation, Lowder believed that she overheard Graf refer to Ow as a panda, which Lowder considered to be racist due to its Asian connotation. However, Graf actually said "Pao Pao", which alluded to the nickname of Big Brother 16 HouseGuest Paola Shea, of whom Ow reminded Graf due to them both being Asian Americans. After being informed of the comment by Lowder, Ow clarified the issue with Graf, but they both later assumed that Lowder had fabricated the comment for game-related purposes, prompting them to confront her. Lowder felt overwhelmed by the confrontation and retreated to the Diary Room where she brought up her history of posttraumatic stress disorder with the show's producers. Concerned of her mental health, Lowder decided that it would be best for her to withdraw from the game.
Viewers called for Jason Dent's expulsion from the House after he was caught on the live feeds making rape and assault jokes in front of other HouseGuests. In one instance, Dent commented on having sex with Kevin Schlehuber's wife, Deborah, while all their daughters would be tied up and forced to watch the act. In an interview with TMZ, Deborah said that Dent's comments were disturbing and "the worst thing she's ever seen." On Twitter, Dent's family apologized for the comments but stated that they were taken out of context, which Deborah doubted as she believed her husband would never joke as such about anyone in any situation. Dent also made similar jokes earlier in the competition, such as suggesting to restrain contestant Raven Walton and have male HouseGuests "take turns" on her, and once telling cops about sexually assaulting women at a nursing home.
Jason Dent and Cody Nickson sparked backlash after footage of remarks regarded as transphobic was depicted on the live feeds. During a conversation in the hot tub, Graf informed Dent and Nickson about Audrey Middleton of Big Brother 17 as the first transgender contestant in the show's history. Nickson proceeded to mock the gender identity of Middleton, for whom Dent was also confused about the appropriate pronoun. Middleton addressed the controversy through a Twitter post, urging people not to vilify both male HouseGuests but rather, educate them on the value of emotional intelligence. Nickson was also criticized for using the derogatory term "tranny" several times earlier in the game.
The extent of Raven Walton's lies in the House became a heavily contested debate among fans throughout the season. She often spoke about suffering from gastroparesis (GP), on which she made several inaccurate or false statements, including its hereditary nature, sterility effect, and terminal prognosis. Even before joining the show, Walton had established a GoFundMe campaign for her treatments, which many skeptical fans considered a scam. Schlehuber also recounted Walton asking viewers for money on camera. Other GP sufferers and organizations like Gastroparesis Patient Association for Cures and Treatment disputed her claims about the severity of her disease, while a plethora of fans condemned them as malingering. However, Walton's mother and her physician took it to social media to combat Walton's critics. Walton also claimed that she and her mother were members of Mensa but their names were disproven to be found in the organization's current directory.
Several House Guests, especially Graf, attracted controversy for certain inappropriate acts in the House. Footage on the live feeds showed Graf making contact with some House Guests in their "private areas" in a joking manner without prior consent. When confronted, Graf dismissed any accusations of such wrongdoing as sexual harassment or invasion of privacy. Ironically, Graf's behavior incited other House Guests like Abrahamian, Matthew Clines, Ramses Soto, and Elena Davies to partake in similar playful acts towards House Guests of the same and opposite genders. In one episode of the show, Ow shared with Martinez how the rampant "touching" in the House, particularly her experience with Graf, made her uncomfortable because it was reminiscent of her cousin who had been raped and murdered.
