Elveonora wrote: The previous episode stated there had been many incarnates, so this episode claiming there were just Hashirama and Madara before contradicts both the previous episode and manga. I believe the old man said that Madara and Hashirama were the first, and Naruto and Sasuke the last (to the current time-period). He doesn't name the ones that were in-between, but it's implied that there were several, as he mentioned in the other episode that each brother had been reincarnated over and over again.
