The ex champion of Unova was just admiring the beautiful waterfall in the island.

She decided to close her eyes and listen to the sound of the water falling, it was a bit relaxing to her as the surrounding seemed quite, it felt like just her and the waterfall.

Not too far away, Zinnia was laying down at the top of the waterfall. Aster, her companion Whismur, lay on her stomach. The girl asked the Pokémon, "Do you enjoy listening to the waterfall?" Even though she couldn't speak human languages, Aster could express her love for this peaceful place. The tiny Whismur performed an ear-wiggling motion, and Zinnia said, "I thought so." Then, she got up, placing Aster on the ground. She'd heard some footsteps coming from below, and it had taken her out of the trance induced by the sound of the waterfall.

The ex champion decided to take a few steps towards the waterfall almost near the edge, then she sat down with her legs crossed again closing her eyes again listening to the sound of the waterfall.

Due to its loud noises she couldn't hear the voice of the other above her so, she thinks she is all alone right now.
