*killua scrutinizes the berries, giving them a sniff.*

who knows. the airship's been coming up with more and more ways to poison me lately. but i'll try them first.

*he takes a small bite out of one of them, chewing it carefully. he's been poisoned enough times to know what it feels like, know the sort of tang and burn to watch out for. but these just seem to be regular old berries, albeit not very tasty ones. he pulls a face, but swallows.*

i guess they're edible. not very sweet, though.
