Tidus blinks, not comfortable in his explanation, but superficial in how he's actually feeling. Spira making him numb to the morbid detail that one battling some form of the undead - their memories, their loathing, whatever fiends really are - to how another may find discomfort in such talk. Until he happens to raise his gaze from Sizhui, sees as the guy speaks the look on Inigo that both puzzles and concerns him.

It's a flicker, before he returns to Sizhui, a small 'oh' escaping him as he explains. A whole world more than what he listened to, but that likely hadn't been relevant to the one discussing it.

Nevermind though. Sizhui raises, cheerful and pleased, and Tidus lets out a small pleased sound before turning a thumb on himself. "Tidus! Too bad we didn't think to buy some mirrors. Inigo went wild back there. You're gonna have a repeat customer."

He grins, adding to the positive mood, to bring Inigo's attentions back to hair than anything of the conversation.
