"End up not looking at anything ever again." Casey retorts with a bit of bite, but no anger. Only a tired insistence in his tone. He pulls the water up in his cupped hands and forces it to run down through Kira's hair, ignoring the mess he makes of the floor and his own pants. It takes little effort to work his fingers through Kira's hair until it moves from damp with sweat and rough with dirt to wet with neither. The water is likely to be a mess when they're through, but for the moment his focus is just in scrubbing the dirt out of Kira's skin, and lightly rubbing it off his skin, determined to help Kira get back to some state resembling a shadow of his usual self and less like a cannibal waif lost in the ash fields.

There's nothing he can do to help save Kira from the nightmares, waking or asleep. He doesn't have the power to take away mistaken connections, or anything else in Kira's mind. All he can do is help get the earth and the salt off his skin. Help him come to something resembling the clean he sought out so often and force him into bed. Physical rest with mental turmoil was better than no relief from either. He finds a scrap of cloth and dips it into the water, letting the barrier between them put some level of distance into the scrubbing of Kira's skin, but no such barrier for the hand still scratching Kira's scalp in a slow, soothing pattern, familiar only because Kira had used it on him.
