[ While Rei had jumped in response to the older man suddenly seeming to appear out of nowhere, Killua just frowned a bit. So he was right. He had sensed that there was another presence in the room but he hadn't been able to pinpoint where until the other had shown himself.

Said guy who he assumed was meaning to help so it wasn't as if he had any real complaints about it, blinking a bit when he heard Yamamoto's words. Killua had just only really met Yamamoto but yet the injured teen was telling them not to kill him despite being in such an awful state. It'd distracted him long enough, the hand on his shoulder making him blink a bit before nodding and moving aside so the older man could get to work. ]

I don't know how much of a comfort it will be, since we didn't quite get to exchanging names.

[ A sigh. God. Why did this guy weirdly remind him of Gon in this moment? The similarities both amused and frustrated him because it reminded him of the separation him and said friend had agreed upon, not that long ago. Though giving a name to this woman here wouldn't hurt and he didn't feel like being more stubborn about all of this mess. ]

You can call me Killua. Doubt last names matter so I don't see the need in giving it unless you absolutely want it.
