#shippuuden ep135. Could do w/o the extended flashback, but I can't say its unnecessary. #anime 

Word of advice.  When watching a fight b/w two experts in genjutsu, don't believe a damn thing.  I've waited SO long for this fight, I almost can't believe it's happening.  They better whip out the really good animation for this finale!  Itachi has always been one of my favorite characters, ever since he first appeared after the 3rd Hokage's death.
