Personality
Sadie is most notable for being the Katie's best friend. They do everything together, even wear the same outfits (which Katie sews herself). Like Katie, Sadie is a sensitive, cheerful, and sweet-natured girl. She is boy-crazy and when she has grown attracted to someone, she (and Katie) will fawn over him endlessly. With her now competing alone, she has grown to not trust many people and to think logical about everything. She is now more villainous and will try everything in her power to get as far as possible.

She is satisfied when her team places second again and begins to go scheme off screen to the losing team.

When Lightning does understand what Chris' instruction are, she calls him stupid to which he retaliates by asking her what else is she going to do. Later before the challenge, Lightning insults her which causes her to say: You are a egotistical, idiotic jock and you need to be gone! LIKE EVA!. During the challenge, she dances with Alejandro and they earn a lot of points. After she finishes, she goes to go find a shiny object to sabotage the other teams. She finds one and holds it up to the sun blinding the Destroying Dragons and successfully sabotages their chances of winning. She then throws the object at Trent injuring him. After Trent accuses her of sabotaging his team, she fakes cries and runs back to plane and then tries to comfort Amy.

During the challenge, she cheers on her teammates and when its her turn, she fights furiously but majorly fails. When it is announced that her team had lost the challenge, she was upset and waits at the elimination ceremony. When she is in the bottom two with Zoey, she gets nervous and when Chris says she is safe, she gets excited but he was only messing with her and says she is the one eliminated.
