Survivor: San Juan del Sur

 Survivor: San Juan del Sur — Blood vs. Water, also known as Survivor: San Juan del Sur, is the 29th season of Survivor.

Development
The theme and name of the season were announced at the reunion show of. The production flew back to San Juan del Sur, Nicaragua, the same location where and  were filmed. Filming began June 2, 2014, and was completed on July 10. After filming wrapped, it was confirmed that the two upcoming seasons will have an all-new cast.

Originally, the season was set to have a 20-player cast. However, 48 hours prior to the start of filming, a member of a pair of sisters (now known as So Kim and Doo Kim) failed one of the final medical examination. Unable to find a replacement pair of the same gender composition in time, production was forced to start the game with the remaining nine pairs, ostensibly having an uneven 10:8 ratio between males and females. The healthier of the sisters, So Kim, was brought back for next season. A similar case occurred back in, where Mellisa McNulty was pulled from the game due to last-minute panic attacks. Former contestant and Survivor Live After Show host Parvati Shallow went to the production site as part of the press who conducted interviews to the contestants and wrote an online journal about her experience.

In an interview with Dalton Ross from Entertainment Weekly after the Cagayan finale, Jeff Probst initially stated that Redemption Island was slated to be in play. However, after the interview, last minute changes were discussed by Jeff and production to further innovate the upcoming season. In a more recent interview with Ross for EW Morning Live, which was held live on set, Probst revealed that they decided to shelve Redemption Island, which potentially misled the contestants, who were yet to be flown on location and listened to the prior interview. The set that was supposed to be the Redemption Island Arena would be rehashed for Exile Island, a twist long-unused since. Jeff teased: "prod"

- We all started looking at it, and it started feeling like—I don’t know. I don’t know if Redemption Island is the right thing. And it would be the safe thing to do, because we knew it worked. I got the cards out and started looking at all the players in my living room and just started imagining: What else could you do with people who love each other that would really make it difficult? And we came up with an idea, and everybody puts their two cents in, and we formed a new idea. Instead of Redemption Island, we decided: We have this arena being built. What if instead of that, we use it for something else, something that will make Blood vs. Water a little more interesting. A little more bloody.

In another interview, Probst added that former The Amazing Race contestant and avid Survivor fan Mike White heavily contributed to the shift from Redemption Island to Exile Island and the Redemption Island Duels became the "Hero Duels."

On August 13, 2014, editors temporarily halted the post-production process of the season and went on strike due to CBS preventing them to unionize which would give them pension plans and health benefits similar to other to the workers in Mark Burnett's other shows. The next day, an agreement was settled, and the editors concerned were allowed to unionize and went back to work, thus keeping the premiere to air on schedule.

Twists/Changes

 * Blood vs. Water: Nine pairs of castaways, each with a pre-existing relationship, will compete against each other for the million dollar prize. The pairs will be separated, assigning each member to opposite tribes. Unlike the first Blood vs. Water season, this season will have an all-new cast. Also, unlike the first season, Redemption Island will not be in play in San Juan del Sur.
 * Day Zero: A day before the actual game starts, the pairs will be sent out at sunset to different locations to live by themselves for the night. They will then all meet up to be officially welcomed by host Jeff Probst and start the game the next morning.
 * Exile Island: After an eleven season hiatus of the twist, Exile Island returns replacing the initial Redemption Island twist. This season's version of the twist would have its tribal Reward Challenges only be one-on-one duels between castaways. Before the tribe switch, however, the twist is that the ones that would face-off should be between loved ones. The winner of each duel wins reward for his/her tribe while the losing castaway would be sent to Exile Island, along with one of the winner's tribemates, where they will choose between two urns: one with a clue to the Hidden Immunity Idol buried on his/her camp, and the other with nothing.
 * Tribe Switch: When there were 14 castaways left in the game, there was a tribe switch, putting four Hunahpu and three Coyopa castaways on each tribe.

Season Summary
Upon entering the season, the nine pairs of loved ones were separated onto two tribes: Coyopa and Hunahpu. Coyopa had a very rough start, losing three consecutive immunity challenges; while the tribe was initially dominated by the Coyopa Guys Alliance led by John Rocker, Josh Canfield was torn between allegiances to the men and perpetual target Baylor Wilson. After John verbally tussled with members of the other tribe after a challenge, Josh orchestrated John’s ouster and blindsided him with the men’s alliance with Wes Nale and Alec Christy. On Hunahpu, Jeremy Collins and Natalie Anderson, having lost their loved ones first, aligned. After a tribe swap, Missy Payne (Baylor’s mother) came into power on Coyopa, while Josh and Jeremy vied for control on Hunahpu. While both men targeted each other, their conflict was never resolved after their tribe won all the challenges.

At the Merge, two factions emerged: Hunahpu Alliance, led by Jeremy, and the Coyopa Guys Alliance, lead now by Josh, with the dating couple Jon Misch and Jaclyn Schultz in the middle. While they prepared to side with Josh’s alliance for the first post-merge Tribal Council, it was cancelled after Julie McGee quit the game, giving Jon and Jaclyn time to change their minds and side with Jeremy’s alliance to eliminate Josh. Jeremy’s fortune was not to last, and he was blindsided by Jon's own Coyopa Pairs Alliance alliance, and with Natalie's help (turning the alliance into "Fab Five"), they resumed picking off the remnants of Josh’s alliance, with Keith Nale as the last outsider remaining. However, Keith was spared as Natalie spearheaded Jon’s elimination, leaving with a Hidden Immunity Idol in his pocket. While Keith survived the next Tribal Council after winning immunity, he lost the Final Immunity Challenge and was the last player voted out of the game.

Ultimately, Missy, Jaclyn, and Natalie became the Final Three. At the Final Tribal Council, Reed Kelly eviscerated Missy’s character, comparing her to a “wicked stepmother”, while Jaclyn was questioned for having only made moves with others, primarily Jon. Natalie was praised for making bold moves without a loved one's support, and was ultimately awarded the title of Sole Survivor with five votes to win, compared to Jaclyn’s two and Missy’s one.
