Olivia is a generally innocent, adorable, sweet, rambunctious, brave and very beautiful little girl. She cares for everyone, especially her father (who is her only remaining living relative, due to her mother being deceased). She is fond of fuzzy animals, particularly Toby. She becomes irritated when people say her last name wrong (as is evident when Basil gets it wrong on a multitude of occassions) and she typically tells them that her last name is Flaversham (on one occassion, with the help of Dr. Dawson).
