Kate is the only daughter of the McReary siblings. She is often described as the "bratty, sassy one" of the group. She also appears to be quite mature for her age, with her attitude being more around a teenager level rather than a second grader level. Kate's character traits include her sassiness, wits, and easily falling in love, as well as loving when things go her way. She is seen as being the closest to Derrick, both being the youngest of the siblings, and finding his antics to be annoying.
