Which episode do they realize Tobi is Madara Uchiha?
It’s a long way away anime wise, he tells sasuke after sasuke fights itachi. The anime is doing filler episodes now, you will have to wait until….(don’t worry, no spoilers plot wise, just the upcoming fights) Naruto’s Wind Training Kakazu and Hidan capture a jinchuriki Kakazu and Hidan fight a bunch of peeps Kakuzu vs. a bunch of guys Hidan vs. Shikamaru Naruto vs. Kakazu Sasuke vs. Orochimaru Sasuke gathers members Jiraiya vs. Konan Jiraiya, Konan, Pein, and some other dude’s past Pein vs. Salamander Jiraiya vs. Pein (gonna be like 5 or 6 episodes long, and this fight promises to be on scale with fights like lee/garra and naruto/sasuke, probably will be the best fight of the series) Sasuke vs. Deidara Kisame Confrontation Naruto vs. Itachi (kinda) Kakashi and others vs. Madara Itachi vs. Sasuke So you are looking at about a year to a year and a half.
