Blood vs. Water (twist)

Blood vs Water is a twist introduced in the titular season,. It featured returning castaways competing against loved ones, such as husbands, wives, children, parents, boyfriends, girlfriends and siblings. In, instead of returning castaways competing against their loved ones there will be new players competing with or against their loved ones.

History
In 2011, before the conception of the "Blood vs Water" moniker, the Philippine version of the series had pairs of celebrities (similar to its previous season), each with a pre-existing relationship. Unlike the US adaptation of the format, the Philippine version had pairs of local celebrities, and the tribes had five pairs each.

In, the twist split up the tribes with the loved ones being on the red Tadhana tribe while the returning players were on the yellow Galang tribe. The twist majorly affected the season, affecting Tribal Councils and Redemption Island Duels. The twist allowed a contestant on Redemption Island to switch places with their loved one if they were still in the game, meaning the contestant on Redemption Island would join their loved one's tribe, while the contestant still in the game would take their loved one's spot on Redemption Island.

The twist will be used again for, this time with all-new players.

Blood vs. Water

 * According to R.C. Saint-Amour and Colton Cumbie, the twist was originally going to pit blood relatives (blood) against couples of significant others (water), but the last minute substitution of Candice and John Cody for R.C. and her father threw off the balance, forcing the loved ones to compete against each other on opposing tribes. However, this has not been confirmed by production.
 * Rupert Boneham is the only castaway to accept the offer to switch with their Loved One.
 * Of the ten pairs, only three had both castaways reach the merge: Aras/Vytas, Tina/Katie, and Laura M./Ciera.
 * Five of the ten pairs had only one castaway reach the merge: Tyson, Gervase, Monica, Hayden, and Caleb. All of them reached the merge without Rachel, Marissa, Brad, Kat, and Colton respectively.
 * Two of the ten pairs were both eliminated before the merge: Rupert/Laura B. and Candice/John.
 * Coincidentally, both the first person and the last person eliminated pre-merge was a Boneham.
 * Laura Morett and Ciera Eastin have the most combined votes received out of any pair, with 33.
 * Colton Cumbie and Caleb Bankston have the fewest combined votes received out of any pair, with 4.
 * Ciera Eastin is the only person who cast a vote against her loved one, in this case, her mother Laura Morett. She cast her vote against her mother at the last Tribal Council where at least one full pair were present and in the game.
 * Tina and Katie have spent the most days together in the game, playing on the same tribe from Day 14 - Day 24 when Tina is voted out, and playing together on Day 32, when Katie is eliminated.

San Juan del Sur

 * Jeremy and Val Collins are the only pair in San Juan del Sur to have a unique relationship.
 * Of the nine pairs, only four had both castaways reach the merge: Reed/Josh, Missy/Baylor, Jon/Jaclyn,and Kieth/Wes.
 * Jon and Jaclyn are the first, and so far only, male/female pair to make the merge in a Blood vs. Water season.
 * Jon & Jaclyn and Reed & Josh would be the first "water" pairs to play together.
 * Only one pair was completely eliminated: Dale and Kelley
 * Dale and Kelley are the only parent-child pair to not make the merge in a Blood vs. Water season.
