Sadie

Sadie, labeled The Sweet Girl's Friend of the group, was a camper from Total Drama Island on the Killer Bass team. She is currently unqualified to compete in Total Drama Action.

Biography
Sadie and Katie are best female friends for life, (BFFFLs for short) dressing alike and spending all their time together since they were young children. They became best friends when they first met as next-door neighbors. Sadie loves Katie like a sister and becomes upset when being separated from her. While the duo are very similar in interests and personality, Sadie appears to be more logical than Katie and most likely has a better sense of direction, though unlike Katie, she does not have her drivers license. Sadie seems to be overshadowed by Katie for a portion of the series. Katie is thin, pretty and seemingly a little more independent, while Sadie is obese and much less independent than Katie. However, Sadie is forced to become more independent when Katie is eliminated early in the game and she is forced to go on without her. After Katie is voted off, Sadie is devastated (even breaking a piece of the dock off when she is dragged away).

Luckily, Sadie soon starts to become more independent from Katie becoming friends with Bridgette and Lindsay. In the end, Sadie comes out of her shell and finds she is able to continue on and make her own choices even without Katie. She is even able to overcome her worst fear (bad haircuts) in Phobia Factor on her own (and perhaps with some moral support from Lindsay, who had to suffer the same challenge). Despite being called fat by her best friend, Sadie finds comfort when Lindsay comments on how pretty she is. However, she seems to attract some unwanted hate from Courtney after she shot her in the face a few times when being blindfolded (as this was part of the challenge) in Who Can You Trust?. Sadie's small, accidental mishap resulted in her being eliminated in this episode. It was not a complete loss for Sadie, as Katie was there to greet her on the Boat of Losers and instantly improved Sadie's mood. They reunited with a hug, squealing happily into the night.

They are seen together constantly in Haut Camp-ture, admiring Justin from afar. They also seem to enjoy hanging out with Noah, though it is unknown if the feeling is mutual with Noah. Sadie and Katie are responsible for the unfair nature elimination of LeShawna, whom they both greatly admired. When Chris Mclean asks them (in an intentionally tricky way) who they would like to see join them at Playa Des Losers, they both say they miss LeShawna the most, clearly misunderstanding the question. The simple utterance of her name counted as a vote, and their mistake started a chain of other campers inadvertently voting LeShawna off by saying her name.

During the special, Sadie teamed up Justin and Katie, but got in a fight with Katie after Justin abandoned them. Ironically, the fight was over which of the two Justin liked the most, when in fact he disliked both of them as he considered them annoying. After being chased by a moose, they made up on the diving board before it broke. Though most of the campers on the board were able to make it to the dock and the next season, both Sadie and Katie fell in the tub below and thus were unable to make it to the dock in time. Unlike most who did not qualify, Sadie and Katie seem content in not being eligible for Total Drama Action as they care more about being with each other than competing. They are excited to be able to watch the action from the sidelines, nonetheless.

Audition tape
After putting the camera back into an upright position (following Katie's audition tape), she knocks out Katie in a pillow fight. After she realizes this, she immediately switches the camera off.
