This time Hisoka really did sigh before turning his eyes to look out the window. They were missing bars, what if someone tried to climb out? This had to be one of the rare times when he was glad his empathy wasn't as strong as it was... Then this trip would be positively awful. Nothing like passing out everywhere to make a field trip complete.

The boy blinked, turning his eyes back to Ami at the question. "Hm?" A muffin? ...Half of him was tempted to ask what was wrong with it, seeing as how she didn't want it, but then again... she was eating half already so (unless she somehow poisoned half of it) it should have been fine. She didn't seem the type to have ulterior motives either, so... After a moment of internal debate the boy nodded slightly before taking the proffered half, careful not to touch any skin.

"I'm Kurosaki Hisoka," Hisoka replied quietly as a way of thanks, something he was never really good at.
