Puh. Puh. What is with that loudmouthed reaction!? And with every way he can say it, why that? Tidus stares at Inigo like he's crazy, too shocked to say anything until he finally manages to choke it out-

"It's not a wig!"

Inigo better not think it's a wig over there! He honestly can't tell, but then he has Roland being mister cool and collected right there, so he gives up on looking at either of them, dropping himself - slowly - into the actual seat of the chair below.

"It's just good hair dye, that's all. I got it done professionally." He knew he'd be stuck with it for a while - and he was banking on that, to not have the brown show through and have it get it done over and over, especially not with how often he's submerged underwater. Zanarkand may have better products than Aremica than some places, but that's still bleaching your hair.

...but alright, he has to look back at Inigo with a bit of a squint and ask: "What did you think my hair was?"

It's not like this blond goes into the roots, bro...! That was a style choice!
