There's a way that Inigo speaks about his sister that he can understand. He doesn't have siblings himself, never was that guy himself--but that was who people painted him as, always in connection with his father. It's different, but somehow similar. The same.

Most of all, it makes Tidus wonder what it was like growing up with someone like that: someone who everyone else saw as perfect. Seemed to think so himself.

"What was like?" He asks instead, moving on from Inigo's sister, to- "Your mother. You said she liked to dance."
