The Great Fall of China

Plot
The episode opens with the winners sitting in first class. Ian and Kacvinsky are laughing by the mini bar, while Liz, Ashton, Ruchi and Myra talk strategy in the seats. Justin is in the next set of seats spying on them, and thinking about how he can take them out one by one. He establishes since Ashton is the leader, she is the one he needs to target first. Ashton notices him watching, and tells him to join in figuring out the plans for the alliance. He grins and joins them. Serena is sitting there anxiously, because she can't reach the rest of her alliance, and Clayton is sitting by himself on the couch sleeping. In economy class, Caelan is meeting with Jen about what to do about their alliance. With Andy voted off and Nathanael and Caroline, who recently quit, out of the alliance that leaves them two and Serena, saying they desperately needed an ally. In the meantime, Sydney, Channing and Nupur are chatting away and Nathanael is staring out the window. Emily is talking to Lizzie about Caroline's betrayal, and Caroline is sitting alone.

Chris calls everyone into the mess hall, where he says their next challenge will be a race along the Great Wall of China. Liz asks why he is telling them the challenge now and not after they land, and he replies saying that it is because they will be skydiving off the plane to the Great Wall. Everyone, used to Chris's craziness, casually gets their parachutes and sky dives down to the location, barely even flinching. Before the challenge begins, Justin sneaks over to Jen, Caelan and Serena and asks to join the alliance. Surprised, they accept, and Justin suggests squashing Ashton's alliance starting with her for being a threat. He accidentally reveals this in front of Myra, who runs to tell Ashton about Justin's betrayal. Ruchi, knowing about Kacvinsky's alliance, goes over and asks to join up with them in voting out Caelan, which Kacvinsky happily agrees to. Emily on the other hand wants Caroline gone, since Caroline attempted to get her voted out in the previous campfire ceremony. Chris interrupts and says that their challenge is to race to the great wall, get a vehicle, and then race to the finish line. First three to get there win immunity. There are six bikes, four trikes, two skate boards, three pairs of roller blades, one scooter, and a mule. That leaves one person who has to go on foot. He yells go and the contestants all begin sprinting as hard as they can for the vehicles.

Kacvinsky is the first one there, and grabs a bike and heads down the wall. Jen also grabs a bike, as does Sydney. The two shoot after Kacvinsky. Justin, Nupur and Nathanael all reach the final bikes and also shoot down close behind Kacvinsky, Sydney, and Jen.

Ruchi straps on a pair of rollerblades and bolts after them, and Caelan grabs a skateboard, runs, lays it on the ground and hops on. Clayton also grabs a skate board, and Ashton straps on some rollerblades. Serena also straps on rollerblades and Lizzie grabs the scooter. Emily and Liz both grab trikes, and follow the crowd, and Myra and Caroline grab the last trikes. Ian grabs the mule leaving Channing to have to go on foot. The contestants are bolting down the great wall, lead by the bike pack. Justin kicks Kacvinsky's bike sending him hurdling over the side of the wall, and Jen sets off one of the explosions that Chris placed along the wall and flies off as well. Ian's mule decides to switch directions and begins going backwards across the wall, and Clayton's skateboard breaks causing him to tumble to the ground. Liz quits the challenge after she gets tired, and Lizzie's crappy scooter falls apart halfway through the race. The first to reach the rest stop (halfway point) is Sydney, who quickly grabs water and continues.

Nathanael, Nupur and Justin are close behind. Just as Nupur gets off her bike, Justin throws it over the side of the great wall and blames Nathanael, causing Nupur to get angry at Nathanael. Justin continues and Nupur continues to yell at Nathanael. Nathanael continues, and Chris announces that if you lose your vehicle you are out so Nupur is out. Next to reach the halfway point are Ruchi and Caelan, who both grab water and continue, and Ashton reaches it soon after. Serena comes right behind and gives up there after being too tired, and Emily, Myra, Caroline and Channing take up the rear. Justin shouts out that Myra is in trouble, causing Sydney to turn around and causes Justin to take the lead. Sydney turned around right into another explosion sending her off the edge of the wall as well. Channing is jogging when she trips and twists her ankle, DQ'ing her from the challenge. This leaves Justin, Nathanael, Ruchi, Ashton, Caelan, Emily, Myra and Caroline still in the challenge. At the 3/4 mark, Justin and Nathanael are neck and neck, and right behind them is Ruchi. Then one of Ruchi's roller blades breaks so she is sent flying off the edge as well. Ashton is closing the gap between her and the bikers, and Caelan accidentally goes barreling into Myra sending both of them over the side. Emily uncharacteristically sabotages Caroline by ramming her trike into Caroline's trike. Both of their trikes break causing both of them to be disqualified and outraging Caroline. Ashton catches up to Nathanael and Justin, and Justin swings at Ashton but hits Nathanael sending him over the side. Ashton and Justin are neck and neck, but Justin pulls ahead and wins the challenge after Ashton trips and tumbles over the side. Since Justin is the only one to finish he was the only one to win immunity.

At dinner, Kacvinsky tells his alliance Justin played dirty so he wants him gone as soon as possible, but for now he thinks he should just hurt the other alliance and boot Caelan. Justin overhears this, and convinces Emily, Lizzie and Channing to redirect their votes at Caroline because he knows causing a rift in the voting will prevent the Team Victory alliance from getting a majority. Justin also attempts to use Ruchi's hate of Caroline to convince her to also throw her vote that way, without Ashton knowing of this sabotage. At the barf bag ceremony, the contestants sit nervously and go one by one to stamp the person's passport they want eliminated.

Kacvinsky (CONF): I mean, it's pretty obvious, I don't see how you are still in this game *stamps Caelan's passport*

Emily (CONF): You betrayed me, so you are done *stamps Caroline's passport* 

Justin (CONF): Bye, bye teamie *smirks and stamps Ashton's passport*

Nupur (CONF): I can't believe you would do this Nathanael *stamps Nathanael's passport*

Barf bags are handed out to Justin, Ruchi, Clayton, Kacvinsky, Myra, Serena, Ian, Sydney, Jen, Channing, Nupur, Emily, Liz and Lizzie. They are then tossed to Nathanael and Caelan. Caroline and Ashton are the bottom two, and the final barf bag of immunity goes to...

Ashton is outraged, and Justin smirks. He states she made a mistake trying to eliminate him back in the boot camp challenge, and turns to his former team and tells them they will be the next to go, one by one. Kacvinsky glares at Justin's new personality change, and Caelan and Serena look nervous about letting him into their alliance.
