Yeah, even he has to be mentioned... I suppose. Ash doesn't fit in much with anything else. When he was four years old, Ashley took him with her when she left Gio. He remembers nothing about his father, and is not even aware that he has a sister.
He was told all his life that his father went on a journey and never came back. He didn't know who the man was, and he never asked. He didn't want to bother Ashley... she seemed to dislike the subject. As long as he can remember, it's just been him and his mother at their house in Pallet.
As for the whole twerp thing... Well, they don't know, he doesn't know, Gio doesn't know. And he's ten years old...
The future... Well, it's different.
