Gladion admits that he doesn't remember the details because he was quite young, and only recalls his father patting him on his head. Lillie confesses that she only knows their father's face from photographs, and never asked Lusamine about him. Gladion remains hopeful that Tapu Fini will recognize his strength as a and grant him his prayers. Lillie perks up and offers to battle Gladion to help summon Tapu Fini, and Gladion agrees to the idea.

Ash queries why she battled him the previous day, and Hapu explains that she thought Ash was a daikon thief. Hapu tells Ash that he could just battle his classmates. Ash explains that he wishes to go up against many different Trainers to help him prepare for his grand trial against Tapu Fini.

Lillie then formally introduces herself and Gladion to Hapu, who is immediately impressed by Lillie's good manners. Hapu spots some holes in Gladion's clothing and asks if she can mend it for him, though he dismisses her request and goes on to ask Ash for a battle. Lillie is fine with the idea and thinks that the heated match will help summon Tapu Fini. Ash pleads with Hapu to stay and watch the battle, though she is none too pleased. Gladion then asks Ash if they can have a battle between their, and Ash is immediately excited by the prospect.
