"Last time on Total Drama World Tour, the final five landed on the famous Wawawankwa campgrounds and participated in a flying challenge. The evil Alejandro won invincibility and chose to boot Cody out, making Sierra cry. The final four! Who will advance to the final three and who will be left behind and place fourth? Find out right now on Total Drama World Tour!" Chris introduces.

The scene switches to first class with Katie sitting uncomfortably while Alejandro drinks soda.

Katie: (Confessional) Alejandro's behind Sadie's elimination. I know he's up to something. I really wish Sadie or Leshawna were still in the game. Without them, I feel really lonely. I hate Alejandro.

"So, Katie…Why do you hate me?" Alejandro smiles.

Katie looks at him before exploding "Why? You got rid of Sadie and Leshawna. Now there is nobody here who I really feel I can trust, except maybe Sierra! You, like, think you're ruling the game, but I can assure you that soon you'll be eliminated because nobody here likes you!"

Alejandro looks at her calmly before saying "No wonder you hate me. However, I am saving you Katie. I am offering a chance to protect you. Sierra and Heather are in an alliance. That's why I brought you here, so we can get back at those two."

Katie looks at him uncertainly before saying "Sierra and Heather are in an alliance?"

"Yes, Katie. Why don't you join me? You can fully trust me. After all, I warned you about Scott, did I not?" Alejandro asks.

"Y-yes…" Katie says. "OK…I guess."

"Good answer." Alejandro replies.

Alejandro: (Confessional) It's as easy as one, two and three.

Katie: (Confessional) Of course I see the obvious lies Alejandro is telling me. I need to make him believe that I'm in an alliance with him and then make sure I vote him off tonight with Sierra. She's not really in an alliance with Heather…is she?

In the economy section, Sierra cries while Heather tries to sleep.

"Can you shut it? It was going to happen sooner or later!" Heather shouts.

"I can do whatever I want." Sierra shouts back.

Heather hits her with the pillow she was sleeping on, prompting a fistfight between the girls.

Time fast-forwards to the final four standing in a desert.

"Where are we?" Heather asks.

"Welcome to Alberta, Canada." Chris smiles. "Today's challenge is making a dinosaur fossil with the supplies in the storage room in the jet and any fossils lying around. You will have 20 minutes, now go!"

The four race to the storage room and Sierra finds markers and glue and flees with them.

She stops beside Katie and whispers to her, prompting Alejandro to glare at the two girls.

Alejandro: (Confessional) Sierra must not be allowed near Katie.

"Katie, allow me to help you with your dinosaur." Alejandro smiles, rushing to Katie and ushering her away from Sierra.

Sierra: (Confessional) Alejandro is trying to make Katie in an alliance. It's up to me to make sure Alejandro is voted off.

Heather finds her supplies and walks out before seeing Alejandro with Katie.

Heather: (Confessional) That stupid idiot! I'm in an alliance with him! I'm supposed to be his top priority! I'm so mad at that handsome…cute…(realizes what she is saying) ugly short Latino!

Time fast forwards and the final four are seen standing next to their respective dinosaurs.

"First up, Alejandro!" Chris says.

Alejandro shows his dinosaur, which is actually the Allosaurus. Chris smiles at it. "Cool, but not much creativity there is there?"

Following him is Heather. "My dinosaur is the Chris-o-saurus. It is a little vain and evil and is a carnivore." Heather explains.

Chris frowns at Heather but apparently likes her dinosaur which is composed of little bones and a picture of Chris.

Katie is third and she shows her dinosaur which is made out of bones she found and a fake fur rug. "This is the kitty-saurus. Back then, when there were no cats, so they had this as a pet."

Chris nods and goes to Sierra who has made a dinosaur out of some bones and glitter and pink markers.

"My dino is the broken-heart dinosaur. It had a friend who died early and was sad for millions of years." Katie smiles at Sierra who smiles back.

Sierra: (Confessional) Ours were the best.

Chris then motioned to an electric chair. "I don't want to appear biased about whose dino was the best, so you'll have to vote. If you vote for your own or lie about which one was the best you will get zapped."

Alejandro is first. "I liked Katie's."

Heather says she liked Katie's as well.

Sierra seconds that notion, but gets shocked and grudgingly says she liked Heather's.

Katie then votes for Sierra's.

"Katie's dinosaur has won the first part of the challenge." Chris announces. "Her advantage is getting a post digger for the next part of the challenge, which brings up the question 'What is the best part of the challenge?' The next part is finding one oil barrel dug somewhere around here. The first person to find one and roll it to the jet wins invincibility. However, the last person to find a barrel will be automatically eliminated."

Heather: (Confessional) Damn!

Sierra: (Confessional) Damn!

"Heather gets a prospector kit, Alejandro, since his dinosaur is not imaginary, gets nothing and Katie gets a beach bucket and a shovel. To make it more fun, boulders will be randomly falling to slow you down." Chris says. "Now, go!"

Sierra grabs Katie and the two flee somewhere.

Heather grabs Alejandro and says "What are you doing with Katie?"

"Making her weak so we can boot her off." Alejandro smirks.

"Oh…so you still remember that we are in an alliance mister?" Heather asks angrily.

Alejandro eyes a boulder and sees it rumbling towards Heather. "My feelings for you are not strategy." Alejandro smiles, kissing her before grabbing her supplies and running away.

"Hey-" Heather cries before the boulder lands on top of her.

A bell rings, signaling that the two have to sing a song.

Alejandro:

I'm going to leave you...
...wedged up in a hole. This is how we will end it. This game we have played! This is how we will end it. Your bill must be paid! Heather: Ooooooh! Shouldn't have mocked you for having to dig. Help me out, and I'll be your human drill-rig. Alejandro: You think I'm gonna fall for that?! Ain't a tea party... ... it's combat! This is how we will end it. This game we have played! This is how we will end it. Your bill must be paid! Heather: Ooooooh! I'm wedged in a hole! This isn't right! If I'm goin' down, make a fair fight! It's beneath you-ou, to abandon a girl in a ditch! Offer me my dignity; I haven't got a stiiiiiiiitch! Please, Alejandro. You and I have been the greatest adversaries this game has ever seen!
Is this how you wanna win it - because I got jammed into a pit by a stupid rock?
Is that the victory you want!?
Alejandro:Yes.

"What? You're supposed to say no!" Heather says.

"All's fair in love and war." Alejandro replies, running away from her.

Alejandro: (Confessional) Change of plans, making big-threat Heather gone is my top priority. She is suspicious of me, like Katie, but can actually do something about it, unlike Katie. Besides, this makes the final three easy…but not too easy.

Sierra and Katie dig in the same spot before Sierra shrieks happily. "I found something!" Katie rushes to her and helps her dig it out before returning to her spot and continuing to dig.

Alejandro suddenly jumps out of nowhere and runs away with the barrel.

"Hey!" Sierra cries, running to him, wielding the post digger.

Alejandro jumps on the barrel and keeps running, dodging Sierra and reaching the plane first.

"Alejandro has won invincibility again!" Chris announces.

Time passes and Sierra arrives with another one and Katie comes third.

Heather arrives last with no barrel. She glares at Alejandro.

"Sorry Heather, but you are eliminated!" Chris grins.

"Come on, that's not fair! Alejandro cheated!" she cries.

"Nuh-uh. There's nothing against stealing equipment or barrels from somebody." Chris announces.

Heather groans and runs to Alejandro, punching him and kicking him before Chef comes and drags her away.

"That leaves three contestants: Katie, Sierra and Alejandro! Who will last long enough to get to the final two? Find out next time on Total Drama World Tour!"

Sierra and Katie: (Confessional) Heather's gone…(Just Sierra) …but things aren't any easier…
