How unexpected but beleivable,he already was insane.I like it.You have left a yearning for the third encounter Kakashi anticipates.I hope you write it.The other ,deeper levels,would Sasuke be there to greet Kakashi?It makes one ponder.Smart.The details as Itachi goes to take his eye,the nail enamel,such details made it real.The fic was sexual somehow also.As we suspected or where led to.Kakashi is a pervert,just not a garden variety one.Excellent.
