Somehow Nida doesn’t think Rinoa knows even the half of what Billy told him about his magic. About how he is fated to rewrite the rules of magic. Sounds powerful.

“There is nothing short of him going full Adel or Ultimecia that could make me care less for him. I think he needs someone to talk to. To keep him be less scared of his power. I think maybe you both need that. And as my friends I worry about you.”

Worries more about how Billy might see himself. Sorry, Rin, you have a support network back home.
