[ that click of the tongue is promptly answered with a condescending huff, followed by a snippy, ]

Don't be stupid.

[ which is, sadly, probably the most age-appropriate thing he's said to arakita yet.

now that they're no longer discussing something so personal that he's kept under wraps for so long, some of the stiffness in kakyoin's voice melts away; he sounds much more at ease dealing with what he thinks is a 'stupid question,' than when he is talking about himself. ]

I'd hate to give Yao the satisfaction of managing to kill anyone. But more importantly, you're a living, breathing person -- it's natural that I'd want you to live. This place poses a considerable danger to everyone, even those who are capable, so I doubt you'll survive long if you stay that brash and prickly.

[ it's said sharply, but not necessarily cruelly, and kakyoin pauses for a moment before continuing, his tone of voice evening out to something much more matter-of-fact. ]

You don't have any abilities, and that can't be helped. It's something you had no control over, and it's not something you can change, even with great effort. Bad luck, but no one can blame you for it, and brooding over it would be a pure waste of time. So instead, you should focus on forming alliances -- not groveling. Even the strongest people here have limits to how much they can accomplish on their own, so you'd have to be tremendously haughty to think yourself an exception to that rule. Do you understand?

[ he definitely could have worded it more kindly if he wanted, but it's fairly sound advice, given sincerely and without judgement. ]
