Episode 17 (Sweden Sour):
After the challenge, the campers return to the starting point, where a polar bear frightens everyone. Only after everyone has screamed their lungs out, Courtney points out that polar bears don't live in Sweden. The polar bear sighs, and then takes their head off to reveal that Izzy was in a polar bear costume the whole time. She goes on a rant about Chef telling her that their next location was going to be in Antarctica, but she didn't want the costume to go to waste.
Heather then asks Izzy when and why were they secretly talking to each other. She is startled for a second, then she says that she was just joking.
Right after that, she starts rambling about how she was following the plane around every episode, detailing her adventures about getting to meet and live with the wildlife with each set, learning their languages, and communicating with them. She begins demonstrating some newly learned languages, and the camera cuts off.
Episode 18 (The Aftermath III: Aftermath Aftermayhem):
As Blaineley is getting carried away by the crew at the end of the show, Lindsay pokes Izzy, and points out that she's supposed to be on the World Tour plane. When the realization sets in, she jumps up, and starts sprinting out of the room, while screaming for Blaineley to wait for her.
Episode 19 (Niagara Brawls):
Before the contestants meet up at Niagara, Izzy is seen walking away from the plane with a smug smile on her face, after a private talk with Chef.
On the meetup point, she and Owen spend some time together reminiscing about the earlier parts of their season, and they both regret about what happened in Jamaica. She promises to try to be better to Owen. As they hug it out, Izzy hears a squeal behind her. She turns around and starts running toward the sound, shouting "You can't run away from me!", as she accidentally kicks Owen in the kiwis. He says how much he missed her in a high-pitch sound.
During the Blaineley song, Izzy gets annoyed at Owen more and more every time he drools over Blaineley, starting from just a pointed look to growling at the end.
As Courtney rolls the bear in the challenge, Izzy screams in happiness for Courtney, as she looks even more terrified.
At last, when Izzy rolls, she rolls the bear as well. She is ecstatic, and after the bear rolls down the machine in front of Izzy, it growls at her. She responds in "bearish" (bear-like noises), and the bear suddenly becomes happy, and calmly walks next to Izzy. She says another thing to the bear, and it starts blushing while looking away.
During the race, the bear says something in the megaphone, and Izzy effortlessly jumps through the obstacle course, getting first place.
Izzy keeps getting more and more irritated at Owen, and her comments to Blaineley, as the episode goes on.
In the balance challenge, Izzy picks up the bear with her hands without thinking, and starts running on the rope. She loses balance, and falls. Due to her ability to communicate with sharks too, she gets off without any scratch. However, the bear gets all of its fur shaven clean by the sharks. Izzy bursts out of laughter at the bear, and they start arguing with each other, until they both turn against each other and cross their arms, signalling a break-up (in bearish).
At the end of the challenge, she's captaining the ship of sharks, shouting en garde, as the boat gets closer to the remaining contestants.
During the elimination ceremony, Chris says that the bear received one vote. Everyone looks at Izzy, and she says that it's over between them.
As Owen gets eliminated, she suddenly appears a lot more emotional, running to him, and embracing him in a hug.
She screams at Blaineley during her fake cry, saying that she'll miss him more.
She's standing next to Owen at the door, looking sad as he tries to jump down. After his second try, unlike Alejandro, she collapses after Owen "starts up the engine" to make his jump.
Episode 20 (Chinese Fake-Out):
In the intro, Izzy appears to be spying on Chris. When Blaineley steals the intro from Chris, Izzy has a mischevious look on her face, as she disappears into the shadow.
Izzy also spies on Blaineley during her announcement, and conversation with Chef, taking notes.
At the start of the challenge, she rides a unicycle, which gets her in the middle of the pack. She then notices a landmine on the wall, and instead of getting scared, she saw this as the perfect opportunity to try and get a lead, as she launches herself forward with the explosion. She lands on her face first, with the unicycle shortly following, dropping on her head.
During the challenge, Cody remarks "Where's Izzy when you need her?", while he was stuck on the donkey, with no control over the animal. In the end, he finished just ahead of Izzy in the race, before the gong.
She sits next to Courtney in the eating challenge, and in the first round, after finishing the tofu thingy with ease, Courtney's smell reaches Izzy. She immediately throws up, and is out of the challenge as a result.
Courtney says sorry, and Izzy says it's fine, it's not her fault that she was covered in that smell. After sharing a genuine smile, Izzy adds that there are a few things that smelled even worse somehow that she experienced during her adventures, but this seemed to annoy Courtney instead of making her fell better.
There was one vote on Chris at the ceremony, but no one figured out that she was the one casting her vote on Chris. She giggles as Blaineley says she was asked to host instead of Chris, saying that she would be an even better host than both Chris and Blaineley.
Episode 21 (African Lying Safari):
Izzy claps and jumps up in joy after hearing about all the deadly animals surrounding their place.
When Cody can only speak in tongues, Izzy runs up to her laughing, saying "Silly, that's not actually how fish talk, it goes like this!". After Izzy's fish impression, Cody mumbles something again. Izzy raises an eyebrow, and tells Cody that he's crazy. She then runs away from Sierra and Cody on all fours.
During the football challenge, she dodges every ball coming at her way. After picking up the plums, she smugly asks if that's all they've got. She goes onto a story of how she's once won the dodgeball championship in school, but she gets hit with 3 balls simultaneously while standing still.
Heather still wins the first cricket challenge, but Izzy does manage to complete the second part of the challenge, earning her a slingshot with 3 tranquilizers.
As Heather faces off with the lion, she asks Izzy to shoot the lion with the tranquilizer. Instead, she jumps onto the back of the lion. The animal gets scared, and starts running away with Izzy on its back, cheering.
As the 4 competitors dart each other with tranquilizers, Izzy runs out of a bush, and exclaims that everyone at this place have gone insane. After that, she realizes that she lost the lion, who in her head was Owen in a costume, and she runs back towards the bush to search for the "him", shouting for Owen to come back.
As she hears the bell, she comes back to start singing with full enthusiasm, dancing around, while the others are still just laying on the ground. At the end of the musical, she tells the others that she's been awake the whole time, and there was no need to serenade her.
She then tells the others to look at her awesome magic trick. She does a roll forward, and shoots two pellets in the air mid-roll, with both balls flying upwards at a perfect angle. She starts laughing and asking the others what they thought of the trick, as both pellets land on her head, knocking her out asleep, snoring.
After the elimination ceremony, Chris realizes that Izzy is still asleep in the savannah. He sends out Chef as a one-man search mission to find her.
Episode 22 (Rapa Phooey!):
The episode begins with Izzy meeting up with Chef again in the dining room, where she proposes a dangerous plan to Chef. Gaining inspiration from Blaineley earlier, she wants to host Total Drama, because she'd be a lot more entertaining and professional host than Chris.
Izzy says she knows Chef's dream is to feature in a big movie and become a star, and if he helps her, she would use her connections in Hollywood to make it happen, featuring him and Izzy as the two main protagonists in a fighting movie.
Chef couldn't refuse this deal, so after shaking on it, he goes back to the cocokpit to distract Chris, giving Izzy the perfect chance to shoot her one remaining tranquilizer from the previous episode at Chris. It's a hit, but when Chris falls onto the control panel, the plane starts taking a nosedive.
Izzy screams into the microphone out of both excitement and fear. Regaining her cool, she then fakes Chris' voice and tells the contestants that they'll be performing a super awesome landing on Easter Island. She then starts telling one of the crazy stories of hers on the microphone, before suddenly stopping, realizing that this might've give it away to the other islanders. After landing, Izzy locks Chris inside a cabin near the cockpit, and leaves him there.
Izzy puts on a poorly-drawn Chris face mask, and she waits for the others to show up on the starting point. After arrival, the other contestants clock instantly that it's Izzy behind the mask, but she's oblivious, as she starts describing today's challenge with her best Chris impression.
A small wind blows her mask away, revealing her true identity, which is a surprise to no one. After a few seconds of awkward silence and staring, she switches back to her usual voice, and usual self.
Her hosting doesn't change that much compared to Chris' lines in the real show, but only with a twist of her own chaotic delivery (like making up stories about people who've been here before and attempted to steal eggs, or about what animals are present on the island).
Izzy grants herself immunity, and Heather starts arguing with her, saying that it's not fair. Izzy threatens Heather first with elimination, but that doesn't faze Heather. Izzy then threatens to bring back Chris, and let him host today's challenge. Everyone begs Izzy to not do so, and Alejandro talks Heather down from bickering further, making her accept Izzy's rules.
When Cody asks why's there a statue of her on the island, she said she commissioned it using the remaining budget of the show.
She spends the entire first half of the challenge sitting on the head of the Owen statue, as she's doing a Steve Irwin impression, commentating the other islanders' progress.
When the musical bell is heard, Izzy runs to the other contestants super hyped, and starts singing and dancing. Heather and Alejandro stops her in sync, saying that musicals meant to be the competitors' job to sing, not the host's. She reluctantly agrees to stop singing, and so the musical begins.
After the challenges, the elimination ceremony happens with the same votes as the real show. Izzy excitedly claims that she made it into the final 4, as Sierra was eliminated with 3 votes.
Before Izzy can order Sierra to jump off the plane, Chris kicks down the door of his makeshift jailcell. Izzy stares at Chris, says "Uh-Oh", and jumps out of the plane screaming and laughing, without her parachute. Chef shouts after her about his role, but he gets no response.
Chris says he isn't mad at Izzy or Chef, because this special episode has skyrocketed engagement rates of the show, and he would've allowed Izzy to stay in the competition instead of Sierra, but she's now eliminated, because she jumped off the plane. Sierra wasn't eliminated as a result of this.
Chris gives Chef a slap, for interfering in the competition, again, but says that he won't receive punishment any further, as long as this was the last time he has done it, pinky promise.
