Sadie was a camper on Total Drama Island, as a member of the Killer Bass. She did not compete either on Total Drama Action or Total Drama World Tour, but appears during the Aftermaths as a commentator. She was seen with the original contestants on a yacht in the first episode of Total Drama: Revenge of the Island.
Sadie is most notable for being Katie's best friend. They do everything together, including wearing the same outfits (which Katie sews herself). Like Katie, Sadie is a sensitive, cheerful, and sweet-natured girl. Sadie shows herself to be rather emotional, even more so than her best friend. She cries whenever she is upset, and lashes out at those who cause her anger. She is boy-crazy and when she grows attracted to someone, she and Katie will fawn over him endlessly. Sadie can be considered the more logical one between the two. Her biography even states that she "thinks with her head", contrasting to Katie who "thinks with her heart". Sadie was even the one who came up with the idea of their summer job, which involves making their own ice cream and selling it at the pier where they live. It is implied that Sadie is the more logical of the pair, but her silence during her time without Katie may imply that Sadie is the less independent of the two.
When Sadie and her best friend, Katie, arrive in Not So Happy Campers - Part 1, they are both ecstatic to be there, thinking it's a regular summer camp. Sadie is put on the Killer Bass, which saddens her as she is away from Katie, during which Courtney tries to comfort her while yelling that she needs to be on Katie's team. In Not So Happy Campers - Part 2, Katie and Sadie are still upset about not being on the same team, begging Chris to put them on the same team. Izzy offers to switch with Katie, which Chris agrees to, allowing both Katie and Sadie to be on the Killer Bass as they both jump simultaneously.
Sadie's performance and contribution to the challenges decrease significantly, starting in The Big Sleep. During the Awake-A-Thon, both girls fall asleep quickly. In the next episode, Sadie is ecstatic once she gets to compete but is a common target, getting hit by a dodge ball several times, including once by her own team mate even though she is benched. In Not Quite Famous, Sadie and Katie are instantly rejected by their team for the talent show, after their horrible dancing revolts the rest of the Killer Bass.
In The Sucky Outdoors, Katie and Sadie become separated from their team when they see blueberries and begin collecting them. After wandering around the woods, a fight erupts between the girls, as Sadie is mad at Katie's lack of direction skills. The two start arguing about everything, straining their friendship. They eventually find refuge in a cave full of bats, scaring Sadie. When the girls awake the next morning, they come face to face with an angry Bear, whose roaring causes the girls to run away screaming all the way back to camp. When they arrive, they settle their conflict and decide to still remain best friends only to soon realize that they lost the challenge for their team, angering them (especially Courtney). At the bonfire ceremony, Katie is eliminated, causing Sadie to cry. Katie then tells Sadie that she has to stay strong and win for both of them. Katie and Sadie then share their final moments together at the dock before Katie's boat departs, leaving Sadie sobbing.
After Katie's elimination in the previous challenge, Sadie is still crying profusely over her best friend's departure in Phobia Factor. Bridgette tries to comfort her, by saying Katie would want her to keep going though Sadie ignores her. Eventually, Bridgette ends up having to drag Sadie away, causing her to rip off a piece of the dock. When the campers reveal their fears around the fire that night, Sadie says hers is bad hair cuts which Lindsay agrees with. When they had to face this fear for the challenge, Sadie and Lindsay bond, calling each other cute. Sadie and Lindsay complete their challenge and earn a point for their respective teams.
In Who Can You Trust?, Sadie pairs with Courtney for the Blind William Tell Challenge, which required one of the two girls to knock an arrow off the other's head while blindfolded. She is ecstatic to be in this challenge and volunteers to slingshot the apples, which she fails to do as she constantly injures Courtney. Sadie doesn't notice that the challenge is over and continues to shoot apples everywhere, angering Courtney. Sadie later realizes that the challenge is over and owns up to her mistake. Due to her mistake, Courtney convinces the team to vote Sadie off. When she realizes she's eliminated, she gets very upset with her team and calls them all "marshmallow eating freaks". She runs to the dock in tears, but after seeing her friend Katie on the Boat of Losers, Sadie becomes happy and squeals with Katie.
Katie and Sadie are seen together in Haute Camp-ture, admiring Justin at the beginning of the episode, and recap their relatively short time on the show, discussing how difficult Total Drama was and how they survived their first major fight. They also seem to enjoy hanging out with Noah, although the feeling doesn't appear to be mutual. Sadie and Katie are responsible for the unfair elimination of Leshawna, whom they both greatly admire. When Chris asks them who they would like to see join them at Playa Des Losers, both of them say that they miss Leshawna the most, clearly misunderstanding the question. Sadie appears again in finale, where she and Katie take Gwen's side, though they switch over to Owen side when he announces he would hold a huge yacht party.
During the special, Sadie teams up with Justin and Katie, but both girls are abandoned in a cave by Justin when their constant talking annoys him. Sadie later gets in a fight with Katie in the cave, arguing over which one of them Justin likes more. After leaving the cave, they continue to argue as they walk through the woods when suddenly Geoff and Bridgette run past while being chased by a moose, dragging Katie and Sadie into the chase as well. The four of them make up on the diving board to escape the moose, only to be caught up in the fight for the case with Cody, Courtney, DJ, Owen, and Tyler. When the board breaks, they fall into the green jelly pool below and thus were unable to make it to the dock in time. Unlike most who did not qualify, Katie and Sadie seem content in not being eligible for the next season, as they care more about being with each other than competing.
Sadie is seen with Katie in The Aftermath: I, a sideshow hosted by Bridgette and Geoff. When given the opportunity to voice their opinion on the Gwen and Trent breakup, Sadie and Katie side with Trent and even volunteer to be his new girlfriend, though he doesn't appear to be interested. Nonetheless, Sadie and Katie remain consistently sympathetic towards him. Katie tells Geoff and Bridgette that every time she thinks about what happened to Trent, she throws up in her mouth and Sadie admits that too. When debating about whether Heather kissed Trent or whether they kissed at the same time, the two had their third fight but when Trent explains where his number nine obsession came from, they quickly make up.
In the second aftermath, it is revealed that Sadie and Katie have started a Trent Fan Club/Anti Gwen Club. It seems both her and Katie has developed a major new crush on Trent and a hatred for Gwen. They spend most of the episode flirting with Trent, instead of answering questions.
In Celebrity Manhunt's Total Drama Action Reunion Special, Sadie and Katie have patched up their conflict with Gwen, serving as assistants on her web show even though they annoy Gwen. In support of going green for Gwen, Sadie and Katie wear green outfits to the Gemmie Awards. Sadie is shown to be scared of speaking in public, as she starts to whimper when Sierra tells her that ten million viewers are watching Celebrity Manhunt at the time. After falling off the cliff, she and Katie go along with Geoff's search party and does not qualify for the third season.Aftermath: Bridgette Over Troubled Water, Sadie sits in the Peanut Gallery with other commentators. Sadie says that she doesn't care that she didn't make it to the third season, saying that as long as she was with Katie (and Trent), she would be fine. After seeing Ezekiel appear on the wing of the plane and in Chris's hot tub in a video clip, Katie suggests it was a ghost, making Sadie screams in terror at the thought of it which annoys Blaineley. Sadie, Beth and Katie get into a fight over The Drama Brothers, as she is seen dancing and enjoying their music after Harold starts to sing Baby. She (along with Katie) is seen crying after Bridgette sang her apology song to Geoff, I'm Sorry.
In Aftermath: Revenge of the Telethon, she appears but doesn't speak. Like other commentators, she helps to donate money for refueling the plane. In the segment: DJ's World Of Animals, she is attacked by the animals along with other contestants.
In Aftermath Aftermayhem, Sadie is in her usual spot in the Peanut Gallery. When she is given the chance to compete in the third season, the can of peanuts shot at her gets stuck in her gut. It is a normal can of peanuts, so she isn't allowed a chance to compete again.
Despite knowing of his actions throughout the season, Sadie is among those who supports Alejandro for the finale in Hawaiian Style. When she finally meets him in person in Hawaiian Punch, she enthusiastically cheers for him and comments on his good looks. Sadie is very moved by the romantic moment between Alejandro and Heather, even if "it is Heather" according to her. Sadie runs away screaming with the rest of the group when the volcano erupts and is later seen in the ocean with the rest of the contestants. She is last seen swimming away along with the others from the island.
In Bigger! Badder! Brutal-er!, Sadie appears on the yacht with other veterans. She and Katie are shown squeezing Trent tightly.
- View this video for Sadie's audition tape.
After putting the camera back into an upright position (following Katie's audition tape), Sadie and Katie are in a pillow fight. While Katie knocks her lightly with a pillow, Sadie accidentally knocks out Katie in their pillow fight. After she realizes this, she immediately switches the camera off.
Like many other campers, Sadie was included in Total Drama Island's prototype show, Camp TV. Little can be said about her differences in personality, if there were any, as she was not featured in the promo at all, but her initial design is dramatically different from her final design. She is as thin as Katie in Camp TV, but does not wear the same outfit as she does (nor does she wear her hair the same way as Katie does). Sadie's shorts resemble the shorts she would wear in the Total Drama series, but she did not wear a striped shirt and, additionally, wore a scarf.
Her design is recycled in Rock n' Rule as one of the paparazzi, along with Katie's. It can also be seen in the Total Drama Action Alternate Realities clip as one of Heather's friends, and in Celebrity Manhunt's Total Drama Action Reunion Special as Justin's girlfriend that he broke up with via text message.
