It’s common practice for shows like Survivor to cast alternates who are prepared to take someone’s spot if someone backs out between casting and the beginning of filming. For Survivor 49, two alternates joined the fray and host Jeff Probst explained why with a pointed warning at future players.

The scheming doesn’t stop; it just shifts locations from the Big Brother house in Southern California to the Mamanuca Islands of Fiji. A fresh group of 18 castaways, aged 25 to 52, will leave behind the comforts of home and plunge into the unknown. No beds. No privacy. No safety nets. And a million-dollar dream.
