Tidus wouldn't take this hit to his intelligence if it wasn't solely in narration so lightly either!! But lucky for Inigo, he's keeping safely away from the volume of Tidus's voice growing any louder as he chooses being reasonable (that is, trusting in him!) over arguing.

Not that the actual question he asks gets more a noise of 'I'unno' following actual words, which aren't more helpful.

"It thinks I'm an intruder? Or it's just broken." At least Tidus doesn't sound that concerned. "Whatever it was, if another shows up, just whack it again! You can't reason with a computer once it goes screwy. You got to whack it a few times or shut it down."

Tidus: Very patient with technology.
