"...she doesn’t like being made fun of and is easily irritated, shown by her expression when meeting the Jovian moons and when she got mad after Ganymede called her ‘babe’. She is also rather observant, as she is the only one to notice that Titan's name is the only one that Saturn can properly pronounce since he mispronounces her name as ‘Diane’ which makes Dione mad as her name is prononced 'Die-own-nee'. She is also aware of what she does, as she is one of the few moons that are hesitant on ambushing the Earth. Even she dislikes Saturn’s treatment of his moons, but she still avoids directly attacking the Earth at certain extent and expresses worry about the earthlings...(shown in later episodes, her annoyance tends to come out more, mainly due to Saturn's incompetency with them)."
