The answer does seem very Tidus-like. To a point where Inigo has little reason to question it. Or little time, since the question flipped back around to him so quickly - that's exactly what he was trying to avoid here! Can't he just bury his feelings somewhere deep in the sand so no one can ever take a look at them? He'd like that. It's easier to not make people worry about you, and the genuine answer to that question would be pretty worrying.

He manages to casually shrug though, as if his inner turmoil isn't even there. "Sure, it's different. Even just everything on the train is far from what I'm used to, but it's not as if this is the first time I've had to adapt to very different circumstances." At least that is the truth. Maybe he can just try to avoid the parts he doesn't feel comfortable lying about. "So there's nothing really bad about being here. I like meeting all these new people, and seeing all these new places. At worst I guess I kind of miss my sister."
