Betrayal

When he smells blood, Kisame embraces his inner shark, and an already fickle Itachi winds up completely unhinged. When Hidan finds him bruised and passed out in Kisame's clothes, he's torn between thanking Jashin for this stockholming slag, and being an actual friend to a comrade in need.

CW for OOC/"first meeting warning" Kisame, substance, sexual and other abuse, toxic relationships, torture, mental health, and Deidara on ritalin.
