That last scene with Sasuke getting stabbed reminded me of Itachi's flashback, as he described how izanami came into being and how it was cast: a few sensations and images recorded by the sharingan and then looped. could have been the sound/image of the water style attack tobirama pulled, then of tobirama getting impailed, the sound of sasuke's sword stabbing the earth, and then the trapped ninja impailing the caster of the izanami; only to start the cycle over again. it's just like in itachi's flashback and itachi's defeat of kabuto. Perhaps if it fails to trap Madara, he would have Hashirama's trump card in his back pocket. Thoughts?
