Soulmates

 was one of two central twists in Big Brother 9. This involved a man and a woman being paired up as "soulmates" (The exception being Joshuah Welch and Neil Garcia). The soulmates would win HOHs together, vetos together, and they would evict together. The soulmates were disbanded during the third week after the official revealing of Ryan Quicksall and Allison Nichols being evicted. Alarms began to sound and Julie Chen revealed that now they would be playing as individuals, and the eviction was now between Allison and Ryan, with Allison being evicted unanimously.
