Harper is a friend of Xavier Riddle who goes to school with him. She is shown to like dinosaurs.
She appears in the episode I Am Sir Arthur Conan Doyle which is the first episode to reveal her name. She is voiced by Beatrice Schneider and later Nendia Lewars due to Beatrice Schneider being a white voice actress voicing a character that's black.
The birthday party she invites Xavier to is indicated as being her seventh by the blue seven written on a yellow balloon on the cover of the invitation sent to him. She attends school along with Xavier, Yadina, Brad, Brian, Jin, Charlie, Jamie, and Tyler.
Earlier appearances[]
Little Girl is how captions refer her when she says "I play a little every day" at the start of I Am Johann Sebastian Bach.
She plays "Twinkle Twinkle Little Star" on the recorder and Xavier is envious. Later in the episode she plays "Mary had a Little Lamb".
She also appears as part of the Nature Troop at the end of I Am George Washington. Here she is still wearing the same blue top and yellow dress.
At the end of I Am Eleanor Roosevelt it also appears to be her, but in a different outfit. A sleeveless light-purple dress. She still has the same ponytail and the same turquoise stud earrings. Here she is clutching a green triceratops toy.
Xavier recommends she go see Murray and she is holding a dinosaur plushy. It's unclear if this means it happens after he discerns her like for dinos after meeting Doyle, or if he's just really bad at remembering stuff.
Trivia[]
- In the description of I Am Sir Arthur Conan Doyle, Harper is said to be the new girl in school, but Xavier already knows her as shown in I Am Johann Sebastian Bach, I Am Eleanor Roosevelt, and I Am George Washington. It's possible that this episode takes place before those episodes. In I Am Madam President the woman next to Xavier cheering Yadina could be Harper.
- She is of Jamaican descent as revealed in I Am Jackie Robinson (remake).
