It's the same thing Inigo figures, even though he has absolutely no personal experience to back it up. Not even any perspective from someone else, considering he never did dare to ask Tidus too deeply about his condition, about his feelings about it - not wanting to cause anything awkward.

All Inigo has is his knowledge of how awful death is to those left behind, to those constantly surrounded by it. But even so - he can imagine death changes people. Inigo has been on death's door way too many times to count at this point, but it's the fact that he's always been pulled back into life rather than fully pushed into death that's kept him from changing that way as well, he thinks.

".. I'm glad you're a smart guy," he says, softly.

Smart about this, at least. About not wasting a life on a test.

"I mean.. I'd get so scared if I saw anything happen to you." It's a truth. Despite Inigo's babyfit he threw shortly before disappearing days ago, it's nothing he'd actually hold against the other now, all the experiences from the past few days totally having taken Inigo's mind off it.

Besides - Jingyi's his friend. That's just a fact.

"Even if I knew you'd come back." Because it'd still be awful. It would still be something no one should have to go through.
