Sora laughs weakly as he pulls himself back onto Link's shoulder, focuses on the road again. "If I had a penny for every time one of my friends stabbed me..."

The shut up grabs his attention, squeezes his eyes shut for a second. That. Hurt? Why would that hurt? People have told him to stop talking before. He just lets it go because he either knows there will be another time OR he doesn't care. He wonders why this moment is so different? Is it because he's holding his stomach together? That seems irrelevant.

However, the next thing Link says is very odd in context with all that. Sora looks up at Link, still trying to breathe at a normal, human speed. "... It's okay. Is someone else here? You said something about... voices."
