According to a new preview of the next episode of Survivor: Cagayan, Kass McQuillen might already be back with her Aparri alliance.

Reason For Kass Flipping On Alliance Revealed By Sarah?

Kass is shown in a preview for the episode Mad Treasure Hunt helping Jeremiah Wood in finding the Hidden Immunity Idol. While this does not suggest that the two are back to being alliance members, it does suggest that a level of trust may have been established again.

Kass flipped on her Aparri alliance in the latest episode of Survivor, betraying Jeremiah, Morgan McLeod, Spencer Bledsoe and Tasha Fox. It is possible that this alliance will attempt to bring her back to their side in order to regain control of the game.

Either way, the hunt for the Immunity Idol will be on, as several castaways are shown in a tizzy looking to attain the coveted token of power.

The preview clip also teased the two challenges that will be played during the episode. The first is likely a reward challenge in which the 10 remaining castaways are split into two teams of five. One team consists of Jeremiah, Morgan, Spencer, Jefra Bland and LJ McKanas while the other team has Kass, Tasha, Tony Vlachos, Trish Hegarty and Woo Hwang. The challenge involves the team going through obstacles in the water.

The Immunity Challenge is also previewed in the clip, and it appears to be another endurance competition. Each castaway is shown balancing in a structure while keeping a block steady on top of their head.

Survivor: Cagayan airs Wednesdays at 8 p.m. on CBS.
