History[]
The Elite Four[]
Agatha, Lance, Bruno, and Lorelei are present in the Indigo Plateau, when Rusty arrives without an appointment.
After Agatha's death, Lance and the two Elite Four trainers decided not to battle him, and he tells Rusty that they changed the rules and "officially" enlists Rusty as one of the Elite Four members while pleading him not to kill him and the other two. He also updated the Pokédex by adding Rusty's "Scary Magic Murder Bidoof" on the list, which he believes that Peanut Butter was a new legendary Pokémon.
After Rusty & Peanut Butter left, Lance asks if some of them should tell Agatha's family about her death, he and Lorelei call "not it", and the responsibility was pushed to Bruno instead.
