Eat, don't reminisce, Kakashi wanted to say, but Genma was managing both. Kakashi watched him for a long moment, waiting to see if that ugly pallid-green colour washed back over Genma's face, but water and warmth seemed to be doing the trick. Genma took another, bigger bite, and his scent stayed mostly nausea-free. Sliced through with half a dozen difficult emotions Kakashi hesitated to even guess at, underwritten with bone-crunching exhaustion, but vomiting didn't seem to be in the immediate future.

Kakashi relaxed.

Food, water, physical comfort -- there was nothing else he could do for his teammate, other than keep Genma flat on his back and as safe as possible. (Nasty joke, that, deep in the bowls of Iwa's prison. Kakashi tried not to dwell on the thought.) He found a second ration bar -- soy flavoured this time, blessedly unsweet -- and went through the same process of examining it thoroughly while his stomach clenched and growled. No trace of visible tampering or poison. Kakashi resigned himself, and pulled his mask down to his chin. The bar vanished in three bites, chased by another long swallow of water; he yanked his mask back up.

Sticky grain hit his stomach like a gift, stirring only the faintest ripple of nausea. Kakashi ignored it; he didn't have the time, will, or energy to be sick. His fingers found another ration bar, but he let it stay wrapped. There was no telling when they'd be given more food.

Genma was still eating his own ration bar in slow, cautious, half-sized mouthfuls. Still looking inward, as the taste of blueberries took him back to the memory of a teammate who'd likely been dead for years.

His teammate from the last broken mission that had landed him in Iwa's tender care, Kakashi didn't have to guess.

Kobo liked wild fruit. Seijuro wasn't strong enough.

Kakashi wondered if their names were on the monument, knew that Kobo's would be, and wished Genma had kept his mouth closed. Between them, they already carried a lifetime's worth of tragedies -- Kakashi didn't need more. Didn't need to know life details about a captain he'd run missions with twice, and unbent enough to actually consider a good man. And if Genma didn't guard himself, he was going to end up saying something he didn't mean. Something Iwa would be interested in.

"You should sleep," Kakashi said quietly. He pulled a knee up, draping one arm over it, and rested his chin on the crook of his elbow. "Dream about -- something better."
