"Last time on Total Drama World Tour, Sadie debuted on the show and the teams were merged. Katie momentarily became the squealing girl she was on Total Drama Island, before being stung by an eel in Jamaica and seeing sense. Alejandro convinced almost everyone to vote off Scott, but Sierra and Scott, leading him to be eliminated from the game. Katie then talked to Sadie, advising for them to tone their friendship down a bit, making Sadie mad. Mad enough to join Alejandro's alliance! The final seven! Who will win invincibility? Where are we headed? Find out right now on Total Drama World Tour!" Chris introduces.

In first class, Cody is sleeping while Sierra eats some pizza.

Sierra: (Confessional) Winning invincibility first is good and bad. It's good because it confirms that you're a good player. It's bad because it makes you a big target in the game.

"Cody-kins." Sierra says, poking Cody, who lazily opens one eye. "Let's form an alliance!"

"Why?" Cody asks suspiciously.

"Because I am a threat because I've won invincibility and you are 'expendable' because you placed 17th in Season 1." Sierra points out.

"Sure…I guess." Cody says. "Now can I go to sleep?"

"You're so cute!" Sierra says, running to hug him. "Sure, go to sleep. We have to win invincibility."

In Economy Class, Sadie giggles while Alejandro talks to her.

"You're so wonderful chica. I don't know why you didn't make the final two in Season 1." Alejandro smiles.

On the other side, Heather rolls her eyes.

Heather: (Confessional) Only Sadie is dumb enough to fall for that. I wish I could just step in and save the day, but no. If I do, I will playing into Alejandro's obvious plan.

Katie looks on worriedly as Leshawna files her nails.

"I'm worried about Sadie. Alejandro is kind of suspicious, what if Sadie gets eliminated?" Katie asks.

"Don't say that about Alejandro! He did warn us about Scott trying to eliminate us." Leshawna replies.

"I don't know… No offense to Sadie, but she isn't the kind of person someone would just randomly form an alliance with. I have a feeling that Alejandro's playing a trick on us." Katie grimly remarks.

Leshawna looks at Alejandro before glancing at Katie. "Are you sure you're not jealous that Sadie is in the hands of that hot Latino?" she asks.

Katie blushes.

Katie: (Confessional) I just wish Sadie didn't take my talking to her so personally. I just advised toning our friendship down a bit and she acts all irrationally.

Katie walks to Sadie and Alejandro. "Sadie-" she begins.

"Go away loser." Sadie says rudely.

Alejandro smiles at Sadie, ignoring Katie.

Katie drops her head down and goes back to her seat.

Time fast-forwards and the final seven along with Chris are seen in a room, with the seven teens sitting in front of a table.

"Where are we?" Sadie asks.

"China!" Chris announces. "Originally we were going to do a race beforehand, but we don't have enough money to do it, so let's go move onto the eating challenge!"

Leshawna smiles a bit.

Leshawna: (Confessional) I drank cockroach juice on the island. I can easily win this.

"You each have to eat disgusting, but traditional Chinese food. Each round, the person that finishes last or doesn't finish their meal will be out of the challenge. The last person to still be eating wins invincibility." Chris explains.

Alejandro looks slightly worried before resting his eyes on Sadie.

Alejandro: (Confessional) My body is my temple. I can't eat disgusting garbage. However, with Sadie as my alliance member, maybe this can help me win.

"First course, donkey meat!" Chris says, putting plates in front of the contestants. "While you eat, let's sing!"

The teens groan as they break into song:

Chris: A little Chinese lesson, for you. Manman chi means "enjoy your meal." Everyone (except Sierra):Manman chi. It's no raw deal.
Cody: Is it roasted eel?

The teens eat quickly. Alejandro whispers something to Sadie before passing her his plate under the table and ducking down.

Leshawna finishes first, followed by Sierra and Katie. Heather and Alejandro also finish (To explain his ducking down, Alejandro says he dropped his spoon) and Cody is the last.

Sadie, finished with Alejandro's food and now chewing her own is eliminated from the challenge. "Don't worry chica, I'll make sure you aren't eliminated, just keep eating the food." Alejandro tells her before she moves to the "loser" box.

"Next up, live mealworms." Chris says, grossing everyone out.

Chris: Manman chi means "bon appetite." Sierra, Alejandro, Heather, Leshawna and Cody: Manman chi. What do we have to eat? Heather: It's still moving its "feet"!

Alejandro ducks under the table again as everyone eats hurriedly.

Sierra and Alejandro finish quickly ("My shoelace was untied" Alejandro says), followed by Leshawna and Katie. Cody and Heather try to eat, Cody scooping up the worms and Heather just trying not to barf.

Heather inhales and finishes her dish.

"Cody, you are eliminated." Chris says, motioning for him to sit next to Sadie.

Cody looks at Sadie, who tries to hide the food in her mouth, unsuccessfully.

Katie looks at Sadie and their eyes meet before Sadie looks away, mad.

"Third dish: roasted starfish on a skewer." Chris smiles.

Chris: Manman chi. It's dinner for five. Sierra, Heather, Leshawna, Alejandro, and Katie:Manman chi. Are we going to get hives? Heather: I think I'm nearly done for.

Alejandro explains that his shoelace is untied and ducks down while Leshawna finishes first.

Sierra and Alejandro come in second and third, leaving it down to Heather and Katie. Katie tries not to throw up and beats Heather.

"What?" Heather cries as Chef moves her to the seat next to Sadie and Cody.

"Fourth dish: Bird Nest Soup!" Chris moves on.

Chris: Manman chi. Don't get the squirts.
Leshawna, Sierra, Katie and Alejandro: Manman chi. We'd rather eat our shirts!
Heather: Wait, stop!

"What?" Chris asks angrily.

"Alejandro's passing food to Sadie!" Heather says, triumphantly pointing to Sadie trying to stuff the soup into her mouth.

"Is this true?" Chris turns to Alejandro.

"Maybe…" Alejandro smiles meekly.

"Sadie has to wear a mask in order to make sure she doesn't eat any more food." Chris says, Chef placing a dragon mask on Sadie's head.

The four go back to eating, Leshawna coming in first, followed by Sierra and Katie, leaving Alejandro out.

"The final dish: the mystery dish!" Chris bellows, breaking into song soon after:

Leshawna, Katie and Sierra: Manman chi. (off-key) Manman chi-i-i.
Chris: They love to eat on The Yangtze. Manman chi. Manman... Huh?
Leshawna and Katie: (both gag and vomit)

"Sierra wins invincibility for the second time in a row!" Chris yells, prompting Sierra to go and hug Cody.

"Also, a little surprise. Mostly due to budget cuts, there will be a double elimination tonight!" Chris says, making everyone gasp.

On the plane, Katie goes up to Sadie and says "Hey."

Sadie looks at her. "What do you want?"

"I wanted to tell you that, well, Alejandro is using you. Don't you see? He was using you to eat all of his food, but as soon as he thinks you're not useful anymore, he'll dump you. What I'm trying to say is, don't be mad. I'm sorry if you were offended with what I said, but-".

"Stop it!" Sadie says. "Stop it. You're just pure evil. Go away!" she cries, running away.

Katie looks on as Leshawna comes by.

Sierra and Cody, in a different part of the plane, debate about who to vote for. "Let's vote off Leshawna. She's a big threat in the game right now." Sierra says.

"OK." Cody agrees.

"Who are we voting for?" Sadie asks Alejandro.

"Leshawna." Alejandro answers. "OK!" Sadie says, skipping off.

Alejandro smiles evilly before looking for Heather.

"Hello Heather!" Alejandro says.

"Get away you goof!" she answers.

"I was just wondering who you want to vote off. Possibly Sadie?" Alejandro asks.

"You, dumbhead." Heather says.

"Why not Sadie?" Alejandro replies. "With her out of the way, we could become the power duo!"

"No!" Heather yells.

"Come on Heather. Besides, you could never vote me off. You like me too much." Alejandro says, pushing her closer to him.

Heather blushes furiously. "I-I…"

Alejandro's lips touch hers and they kiss.

After the kiss ends, both of them look at each other.

"Vote off Sadie?" Alejandro says.

"O-OK…" Heather responds.

Heather: (Confessional) I DO NOT like Alejandro. This is all, um, strategy.

Alejandro: (Confessional) I DO NOT like Heather. This is all, um, strategy. The reason I'm, voting off Sadie and not Cody is because with Sadie gone I can see if Katie's weaker. Also, I'm going to see just how good Sierra is in the game. If she wins invincibility once more, Cody is going down.

In the elimination ceremony, Chris smiles at everyone. "Tension! I like it! The first barf bags go to Sierra, Cody and Katie. Let's see the rest of the votes, just for fun!"

A TV comes down from the ceiling and Cody's vote is shown.

"I vote for Leshawna." he says, making Leshawna gasp.

Heather is next. "I vote for Sadie."

Sadie looks worried.

Katie's vote follows. "My vote is for Alejandro." Alejandro looks at Katie, who looks terrified.

Leshawna's vote goes to "no-good Heather. Even though Alejandro cheated, I still think Heather should go."

Sadie's vote is for Leshawna, making those two votes Leshawna and one vote for Sadie, Alejandro and Heather, respectively.

Sierra's vote is for Leshawna. "Leshawna, you are eliminated." Chris says, tossing her a parachute.

Leshawna looks shocked before saying "We didn't see Alejandro's vote! Who's the second eliminated?"

"Ahh…that's the best vote." Chris smiles.

Alejandro stamps someone's passport before showing it to the screen. It is Sadie's.

"What?" Sadie cries, tears flooding from her face. Leshawna and Katie gasp.

"I told you not to trust him." Katie points out before going to Sadie.

Sadie looks away from Alejandro and hugs Katie. "I'm so sorry we were fighting. I should've just, like, taken you're advice. Watch out for him BFFFFL." Sadie says, before taking the jump with Leshawna.

"Bye Katie!" Leshawna cries. Katie waves to her and Sadie before breaking down into tears.

"Sierra, who do you want to take to first class?" Chris asks.

"C-Katie." Sierra decides, shocking everyone.

Sierra: (Confessional) I feel so bad for Katie. She needs someone understanding. That someone has to be me, since two people on this plane are evil.

"That's the final five for you people! Will Sierra keep winning invincibility? Will Heather and Alejandro keep their alliance? Find out next time on Total Drama World Tour!" Chris concludes.
