Katie came to Total Drama Island with her BFFFL (Best Female Friend For Life), Sadie. Katie first met Sadie when they first became neighbors and were inseparable ever since. Katie and Sadie,are the only contestants whom knew each other before entering the competition. They joined Total Drama Island to become even better friends. Though she and Sadie are very similar in personality and interests, Katie seems to be the pretty and smart one of the two, which would be natural since Katie is much thinner and taller than Sadie. She also seems to have a bad sense of direction, which comes to be her downfall later in the competition. Katie and Sadie are not taken seriously by their fellow peers (most likely because of their bubbly personalities).
