I was thinking like there would be 18 people and 1 person on each tribe has a twin. The twin would live on their own and switch during confessionals since most of them are now in isolated spots.
If 1 is voted out, then the twin comes in afterward and continues to play. If both tribes twins make the merge, then they both come in and the merge starts...
Idk, I was just thinking about it since there have been people who have twins in survivor (Cindy from Guatemala). What do you think?
