Question: It was because Casey never wanted to be the Pokémon champion; her main goal was always to be reunited with her lost Pokémon. Over time that goal slowly changed into having a new adventure with her Pokémon but never to being a champion. This is why she was sad when she lost the challenge but never too distraught over it. After the Darkest day, she moved her vision towards the crown tundra and the Isle of Armor, looking forward to a new adventure.
