[Kisame stares blankly at the screen for several long minutes, trying unsuccessfully to reconcile young with dead in his mind, and piece together some coherent explanation for why he's equally certain that both are entirely natural and obvious states for him to be in. He hurts too much to be dead--and even if he was, that wouldn't explain why Itachi is this young, anyway.
He considers attempting a genjutsu canceling technique, if only to see if it helps to clear his head, but decides against it; better to save that for when he's feeling a little steadier. He shakes his head instead, and opts to trust his physical condition, rather than the two wildly different, fragmented stories his memories are trying to tell.]
Un--n-no noteworthy damage, but some physical instability. Chakra system intact and functional. Unarmed, I think.
