Sadie

Sadie is the obsessive friend. She and Katie are best female friends for life, BFFFL's for short, dressing alike and spending all their time together. In her audition tape, after putting the camera back into an upright position, she knocks out Katie in a pillow fight. After she realizes this, she immediately switches the camera off. Katie and Sadie became best friends when they first met as next-door neighbors. Sadie likes her best-friend-for-life Katie, and dislikes being separated from her. Unlike thin Katie, Sadie is overweight. However, throughout the series, only Katie herself has made the remark that Sadie was overweight. While Katie thinks with her heart, Sadie thinks with her head. Sadie is rewarded with four marshmallows. After Katie is voted off Sadie is devestated but she eventually gets over it and makes it by by becoming friends with Bridgette and Lindsay.

In an unaired episode, it is revealed that she really loves banana bars but Katie was allergic to bananas. She ate too much banana bars (with 100 fats) that she became overweighted (which is why she is so fat). He tried to lose some weight but thinks it is too much trouble.
