Of course Evie's dragon has a complicated temper and isn't good at working with others, she would be able to empathize
Also more foreshadowing to the bad ending the story has in store for her, which absolutely in no way would ever be connected to what looks like future Elsa traveling through time to save her again and again or to that mysterious "dark power" she is slated to receive as the villainess to stand a chance against Elsa's ridiculous abilities
