Now that was a good chapter and it certainly answers a TON of questions. This chapter was much better then last weeks and thankfully it gets rid of any worries Itachi was ever a good guy at any point. Now we can have a death match that matters.

The downside is .... sense when did Sasuke have the Mangekyou Sharingan? I'm either completely forgetting him obtaining it in the first place or in no way should his eye's currently be of use to Itachi in the first place. Also I thought only Itachi, Mandara, apparently Mandara's brother has ever gained the Mangekyou Sharingan so why is it now that this happened constantly in the clan between brothers and its never been even remotely hinted at until now.

Also is Kakashi's perfect and it doesn't cause him the blindness as a result of it being transplanted from Obito or is Kakashi going blind?
