But when their transportation is accidentally destroyed, an angry host kicks someone out of the game, leaving only three.'''

Recap
During the night when everyone else is sleeping, Alejandro goes to the security camera's to make a realistic photo of Heather and Cody sleeping next to each other in the economy section. Back in first class Heather wakes up and Alejandro again thanks her for inviting him to first class with her. Heather simply says that if she had invited Sierra or Cody, Sierra would be targeting her next to go so she had to pick him. In economy class Cody wakes up, to a very excited Sierra. Sierra explains that the day is awesome, and that she plans to make something "very special" for Cody. Alejandro ask to have a word with Sierra on her way to get Cody's surprise ready. Alejandro shows the picture he made the previous night, and Sierra becomes furious with Heather.

The contestants are taken to Drumheller, Alberta, known for the many dinosaur bones. This brings up the challenge of designing a dinosaur of any type of bones they find, and anything they can find on the plan. During the challenge Sierra is hostile towards Heather, both scaring and confusing Heather, since Sierra tries to hit Heather throughout the first part of the challenge. When it's time to show their own dinosaur's each show different ones. While Alejandro made an actual dinosaur, Heather made a dinosaur named after Chris, even having his picture for the head, which Chris clearly likes best. Cody shows his small dog sized dinosaur made of light rocks, which Alejandro points out that its fossilized dinosaur poop. When Sierra shows her's it symbolizes a broken heart with glitter glue, a dinosaur skull and a party hat. When Cody asks about the hat, Sierra reveals that today is Cody's birthday, something even Cody forgot. Cody is grateful that Sierra remembered his birthday. Chris then shows that the four finalists will now be voting on who's the best in a lie-detector electric chair, not being able to vote for their own. Heather and Alejandro voted for Sierra's, Sierra voted for Heather's Chris one due to her and her mom's crush for him, and finally Cody votes for Sierra's too since she remembered his birthday. Since Sierra won the first part of the challenge, she gets a post digger for the second part. Sierra then points a rotating digger at Heather and chases her with an evil grin.



The second part of the challenge now is to find several barrels of oil that the interns had accidentally buried. Since Heather got one vote, she is given a prospector kit. Since Alejandro's dinosaur is not imaginary, he comes in last and gets nothing, while Cody gets a beach bucket and a shovel for getting third. The major issue though is that Drumheller is huge, therefore it will take forever to find the barrels. For a fun twist, random boulders will be flung into the valley to disrupt the contestants. Alejandro is forced to dig with his bare hands and Heather mocks him for it. Eventually, Alejandro snaps and yells at Heather, demanding that she leave him alone. Taken back by his anger, a terrified Heather quickly leaves.

Cody and Sierra are then seen walking around and trying to find a digging spot. With Sierra being mad, Cody tries to figure out what's wrong with her, but is interrupted by a flying boulder landing right near them, which Cody saves Sierra from. Cody finds the picture Sierra had and wonders how it happened. Sierra is about to tear up again, but Cody points out that since the picture is only of him and Heather, that it can't be real since the only time Sierra leaves Cody alone is when he has to go to the bathroom and the picture is in economy class. Cody and Sierra realize what Alejandro tried to do, and while digging out of anger Sierra finds a barrel. Cody lets Sierra take it for immunity, and both decide that if one of them sees Heather, they will explain what happened, and convince her to vote off Alejandro. When Sierra gets back to the plan, she goes inside to get Cody's surprise ready instead of staying at the barbecue with Chris.

Heather, frustrated with randomly digging, hurls her pick-axe and hits a barrel. Before she can dig it out, though, a boulder traps her in the dirt she had been digging. Alejandro, finding a barrel of his own, hears Heathers cry for help, and goes to check on her. Chris cues them to sing a song, where Alejandro first plans to leave Heather in the hole so she will lose and surely be eliminated. Heather points out that her losing due to being stuck in a hole is a hollow victory and that he should at least beat her fair and square, which makes him reconsider. He holds her for a moment, making her promise to never vote for him again, to which she agrees since there are few votes let. Alejandro explains in the confessional that he just changed his mind about leaving Heather, and didn't help her because he likes her. They bring in the two barrels, one noticeably leaking, and tie for second. Heather is seen in the confessional when Sierra comes in and tells her about Alejandro's scheme.

Chris has a marshmallow ceremony in honor of the first season. Sierra gets the first marshmallow and Heather gets the second, as both did not receive any votes. Chris then reads the votes revealing two are for Alejandro and one is for Cody. Before Chris reads the last vote, Sierra interrupts and asks to go get something before anyone else is eliminated. Sierra reveals Cody's surprise to be a cake with firework-like sparklers as candles. The others realize that Sierra is standing right in the middle of the spilled oil, and that the sparks are starting to fall right into it. They scream at her to watch out, but she doesn't know what they mean. All of the animals and Ezekiel are seen running from the Total Drama Jumbo Jet moments before it explodes. Sierra is then seen covered in soot, and now hairless, saddened that her cake is ruined. Alejandro frantically asks if she is okay, to which she angrily asks him if she looks okay. Chris, now furious about the plane being gone, declares Sierra eliminated, even though she had immunity.

Heather is shown high-fiving Alejandro for making it to the final three with Cody, but Heather rushes to do something important. Heather is seen attempting to burn the votes in the fire, but Alejandro, hiding behind one of the fallen tiki statues, immediately approaches the fire after Heather leaves and manages to pull them out before they burn completely. He finds three votes against him, meaning that if Sierra hadn't blown up the plane, he would have gone home. More importantly: Heather voted him off even though they were in an alliance. Alejandro swears vengeance for betraying him. An extremely sad Chris signs off the show and is almost about to cry.

Cast

 * Ezekiel also makes another cameo, and seems to be screaming with the other animals, but has no lines.
