She has been mean to Arthur at past reunions such as spinning him on the lawn sprinkler, doing judo on him, and dressing him up as a baby. However, at the reunion "Arthur's Cousin Catastrophe," she is much nicer to him. After seeing Arthur play piano at past reunions, she decided to learn how to play. She also reveals to Arthur that he's her favorite relative and that the only she comes to the reunion is to play with him.
