Simply, she devoted herself to graze the meadows of the area all day, without obeying their orders. Therefore, Brock was given Ilta to help her. Through various lessons of Pokémon care, Brock was shown to Autumn as it should treat Ilta to obey him. It was finally when a group of Beedrill would attack them, when he began to value Autumn, for she had brought food for the Beedrill not attack their Miltank. So Autumn began to have an attraction to Brock because of the way of raising Pokémon since she admired and treated with much love and affection for his Happiny.
