Blood vs. Water

Blood vs. Water is a game shifting paradigm employed at the start of the game that stipulates loved ones competing against each other in some form. It was introduced to the wiki in 2012, though under the name "Couples Showdown" - inspired by Survivor Philippines: Celebrity Doubles of the Philippines series (the canon season Survivor: Blood vs. Water started filming in May 2013 - a year after Survivor: Couples Showdown was written).

This type of season format is well known for pitting one tribe of loved ones against another tribe of loved ones, although multiple variations of this format have been introduced.
