#hz075

Looking more closely at the preview for HZ075, it appears that Rystal owned a copy of the Scarlet Book.

Spinel describing someone Amethio as someone "who doesn't know when to give up" when Agate told him that Amethio was probably acting independently. Spinel acknowledging Amethio's perseverance and resilience and still keeping an eye on him, as if he knew that Gibeon dismissing Amethio wouldn't be enough to crush his spirit completely and that Amethio would still find a way to keep going.

The whole thing with Spinel trapping Amethio in a cave with Liko was also another one of these cases of Spinel knowing Amethio too well, because he knew that there was no way Amethio wouldn't cooperate with Liko to get out of that predicament. Spinel using Amethio's nature against him because he knows the kind of person he is and that he wouldn't abandon someone who needs help. In turn, Amethio also seems acutely aware of Spinel's movements and keeps track of him specifically, which is something he doesn't seem to do with the other Explorers.

Rystal doesn't seem to blame him specifically for what happened, while Terapagos and Rayquaza both got angry at Amethio on separate occasions due to his resemblance to Gibeon which indicates that they personally hold him responsible for what happened. It highlights that the Pokemon have their own feelings and thoughts which can be different from how humans feel. The Six Heroes and Terapagos feel loyalty towards Lucius and his memory above all, while Rystal has different feelings on the matter.

Even the way Rystal brought up Gibeon at the end when Friede asked her where Rakua is, and she thought that Gibeon might know.. and then added that she doesn't know what happened to him after the events at Rakua while looking sad. She thought that they could ask him and considers him as someone they could potentially rely on (the way both Lucius and her did in the past). And her words indicate that she still thought about Gibeon after everything and probably lived without knowing if he survived or not. Rystal lost a friend that day too, on top of losing Lucius, Terapagos and the Six Heroes.
