Too much talk in this episode. I understand Kabuto would be happy enough to talk to try to lessen the cooperation between Sasuke and Itachi, but for those two all the chatter certainly wouldn't do any good. I doubt Kabuto would spill any weaknesses. Too many flashbacks as well, like you said, but I'll probably be able to stomach a couple more if Oro is in them.

Izanagi is about changing one's fate, thus allowing to escape certain death, for example. If this Izanami is setting fate, maybe it will allow to guarantee the outcome of an attack if some favourable conditions are present.
