Double Elimination

The Double Elimination is a game changing twist that forces a tribe to vote out multiple contestants at one tribal council. A Double Elimination is different from a Double Tribal Council in several ways: it is not revealed beforehand, individual immunity is not always offered, and the only one tribe has to go to the double elimination. In this way, two members of one tribe go home consecutively.

History
This twist first appeared in Survivor: Cook Islands, when Jeff announced that the loser of the immunity challenge would receive a message in a bottle, to be opened after tribal council. After Rarotonga eliminated Rebecca Borman, they opened the bottle, expecting the merge. Instead, they were instructed to vote off an additional tribe member, and Jenny Guzon-Bae was eliminated.

Appearances
In Survivor: Cook Islands Rarotonga was forced to vote out two members consecutively, after receiving a message in a bottle, for losing the immunity challenge.

In Survivor: Redemption Island, the merged Murlonio tribe received a mysterious package that they were only to open after voting out one tribe member. They then competed in another immunity challenge, and voted off another contestant, eliminating the remaining former members of Zapatera.

In Survivor: South Pacific the merged Te Tuna tribe was surprised when an impromptu immunity challenge was held at tribal council, immediately after voting off a tribe member. Sophie Clarke won her second consecutive immunity challenge, and the tribe unanimously voted out Whitney Duncan, eliminating the remaining loyal members of Savaii.
