Earth, Air, Fire, Water

Plot
The episode opens up with all the contestants sitting in economy class. Sydney is talking to Kacvinsky, about how she feels horrible for turning on Myra, and wants to figure out who framed her. He says he will help, saying he has some ideas. Kacvinsky also figures that now since there are only eight players left, he needs to start seriously considering who to take into the final three with him. Since there is a possibility of a jury vote, he doesn't want to have to stab anyone in the back. He looks around and sees Nupur talking to Sydney, Ian with Caelan, and Lizzie sitting alone.

Kacvinsky (CONF): On one hand, Lizzie's likability could beat me in the finale, but if I choose to stick with Sydney and Nupur they might turn on me like they did on Myra. Sure they didn't mean it against Myra personally, but you can't be risky this far in the game. Also, Ian's friendship with Caelan could prove a threat to me unless I get rid of one of them

Serena walks over to Nupur and Sydney and begins friendly talking to them, trying to get in good now that Myra was gone. She says that they should hide the idol clue again, and immediately returns it to the spot it was found in. Sydney gets suspicious, wondering how Serena knew that.

Sydney (CONF): No. Way.

Sydney runs back over to Kacvinsky and informs him of her discovery. He tells her they need to get rid of Serena next vote, hoping that she won't win immunity. Chris walks in carrying eight robes. He also is holding eight belts, two red, two blue, two grey, and two brown. He tosses the robes to the eight contestants, bows, and begins to tell them about the challenge. He says that they will be divided into four tribes, earth, air, fire, and water. He says he will be doing it based on personality. Serena and Justin are fire, for taking charge and being relatively hot headed. Sydney and Ian are air for just going with the flow and flying wherever the wind takes them. Kacvinsky and Nupur are put on water for going with the flow, but at the same time controlling their own destiny. Caelan and Lizzie are put on earth, for being calm in the face of potential elimination, and steady in their allies. He tosses the contestants their respective belts, and lowers them by ladder, in front of a giant temple.

Team Air: Ian & Sydney

Team Earth: Caelan & Lizzie

Team Fire: Justin & Serena

Team Water: Kacvinsky & Nupur

There are four paths, which each element topping each path. Chris tells them that will have to run up the giant steps, and go down the path that is topped with their element. First team out of the temple and back to the jumbo jet on the other side wins. Winning pair wins immunity, guaranteeing both of them a one in seven shot at the prize money. The other six will be up for elimination. The contestants line up at the finish line, and Chris yells go.

Immediately the group is split, with Kacvinsky, Nupur, Lizzie, Sydney and Caelan pulling ahead, while Ian, Justin and Serena are having a bit more trouble. Kacvinsky and Nupur are the first pair to reach the top, and they bolt down the water room. In front of them is a long flowing river, that goes through the temple. The rapids are fast, and tied to the shore is a canoe. Kacvinsky and Nupur hop in, Nupur unties the boat, and they take off down the rapids.

Caelan and Lizzie are next and begin down the earth tunnel. In front of them is a giant cliff that has platforms sticking out of it. They have to jump from platform to platform to get to the top. Caelan boosts Lizzie up to one of the closer platforms, but it crumbles beneath her causing her to topple on top of him.

The scene flashes to Sydney arriving, and turning around to beckon Ian on. Ian however, has fallen and gone down to the bottom of the stairs giving time for Serena and Justin to pass her and enter the fire tunnel. They are faced with various walls of fire that they would have to maneuver through to get to the other side. The first obstacle is three flamethrowers from the wall, one at foot-level, one at waist-level, and one at head-level. Serena says she refuses to do this, but Justin ignores her and tossed her over the wall of flames. He then does a side jump in between two of the pillars of fire, managing to escape unharmed.

Serena (CONF): Now that individual immunity is much more important, taking Justin out could be important. I have to lose this challenge.

Eventually Ian catches back up to Sydney, and the two ran down the wind path. They have to cross a long, narrow balance beam over a seemingly bottomless pit. On both sides of them were giant fans in the walls, blasting strong gusts of air at them. A montage follows of the contestants doing their challenges, interspersed with confessionals from the contestants.

Nupur (CONF): Do I really want to take Kacvinsky with me to the finals? It would be a tough jury vote between us, Sydney too. But backstabbing him could prove to be just as bad.

Nupur and Kacvinsky were rowing down the river, with a bump almost knocking Nupur out of the boat.

Sydney (CONF): I can't believe Serena, this is like, a whole new level. Poor Myra, Serena better lose this challenge

Sydney was knocked over the edge by a strong gust of wind, but Ian grabs her hand at the last second.

Serena (CONF): Am I worried? No, of course not. I just convinced Sydney and Nupur to take out one of their best friends, I can do anything.

Justin is almost blasted by a flamethrower before Serena jumps and shoves him out of the way.

Justin (CONF): I've gotten my revenge on my ungrateful teammates, look who's the last one standing now, now it's strategy time

Justin and Serena further through the flames, when Serena spots a light at the end and the two quicken their pace.

Caelan (CONF): I'm not really considering taking Ian into the finals with me, a jury vote would likely go in his favor, that's why I have to take Serena

A platform crumbles underneath Caelan, right as he grabs Lizzie's hand to be pulled up to the next platform. She has to work hard to pull Caelan up.

Kacvinsky (CONF): There are so many choices, but right now all I know is I need to win this challenge

Kacvinsky and Nupur approach a giant waterfall and are thrown over the side of it, both screaming the whole way. Once they hit the bottom, they saw the light at the end of the tunnel as well and began rowing as hard as they could.

Lizzie (CONF): Having Nathan, Emily, Caroline, Bailey and Camila gone worries me. Plus, only Nathan, Emily and Caroline would be part of the jury. I really need to figure out my plan.

Lizzie and Caelan finally reach the top, and just needed to climb over a large mound of dirt and slide down the other side to reach the exit.

Ian (CONF): Kacvinsky, Lizzie, Nupur and Sydney are all risky people to take into the finals. Caelan would be a good choice

Ian and Sydney are nearing the edge of the balance beam. Suddenly, the screen flashes to Chris standing outside the jumbo jet on the other end of the temple. Footsteps are heard, and the team that emerges out of the temple was none other than Team Earth. Caelan and Lizzie high-five, as the other three teams arrive right behind them.

The scene flashes to elimination that night. Holding barf bags are Caelan and Lizzie, and Chris has five left. Everyone is sitting nervously. A flashback to dinner shows the contestants all finally forgetting about the game and talking about how much it would suck to be eliminated after making it so far.

Another barf bag is tossed to Kacvinsky. Another flashback shows Kacvinsky, Sydney and Nupur laughing at Ruchi in Piza, since she tripped during their sprint up the Leaning Tower of Piza.

The next barf bag is given to Sydney. The next flashback shows Myra, Brittany, Brandon, Ian, Lizzie and Kacvinsky playing cards in economy class on their way to Hawaii after their Greece challenge. T

he next barf bag is tossed to Nupur. Another flashback occurs of Nupur, Elizabeth, Cassy and Colin in an intense conversation on the dock the day of the cliff-diving challenge.

Another barf bag is handed to Serena. She sighs in relief. The bottom two are Justin and Ian, and the final barf bag goes to...

...............................................................Justin. Ian is shocked, and it is revealed that Caelan lead a campaign against him for being a huge threat physically, and socially. Ian is hurt, and hugs Kacvinsky, Lizzie, Nupur and Sydney good-bye before he jumps out of the plane sadly. This causes Lizzie to look ashamed, since she joined Caelan in voting off Ian instead of helping Kacvinsky and Sydney eliminate Serena.
