Survivor Season 40, Episode 4 airs on March 4 and CBS has released a number of photos before it debuts.

Within the photos, it might be easy for viewers to start making guesses at exactly what is about to take place.

One of the photos also shows the next Immunity Challenge, with a familiar person on the sidelines again.

Quick Survivor Season 40 recap

During Episode 3, Ethan Zohn was voted out at Tribal Council. This leaves just 16 people still in the game.

The other castaways who have been sent to Extinction Island are Natalie Anderson, Amber Mariano, and Danni Boatwright.

The eliminated castaways will have a chance to get back in the game later this season, but they will have to wait for that opportunity to arise.

Below are some of the photos that CBS has released in advance of the March 4 episode of Survivor:

As advertised by CBS, when Ethan joins the other four castaways on Extinction Island, they are going to have a tough task placed in front of them.

According to CBS, “Castaways are on the edge of breaking down when faced with a grueling opportunity at the Edge of Extinction” during the next episode.

The two images below show the quartet figuring out what to do next:

An important Survivor Immunity Challenge

It appears that there isn’t going to be a tribe swap or a shuffling of the castaways during Survivor Season 40, Episode 4.

Below is an image from the next Immunity Challenge, with two members of the Dakal Tribe sitting out. Guess who is on the sidelines again?

In the photo above, it is very clear that Sandra Diaz-Twine is sitting out again. As for the man sitting next to her — that is Tony Vlachos. There may be a backstory to why they are sitting out, but fans have already noted on social media that they are surprised that Jeff keeps letting Sandra not participate in challenges.
