After Jimmy's mysterious disappearance, the happy go lucky girl decides to help take care of the young stranger, Conan, who claims to be a distant relative of the lost Jimmy. Rachel is fearless in the face of danger and always willing to lend a helping hand in the detective work of her father, Richard. She keeps a close eye on Conan in the hopes of keeping him out of trouble and because she sees many of Jimmy's traits in the young boy. Just as with Jimmy, Rachel is never shy about putting Conan in his place because of his age as well as scolding her father for his lazy habits.
