Kabuto is so sneaky using those slick comments to further nourish the hatred within Sasuke's hearts, something Itachi is obviously trying to counterbalance by resurfacing memories the uchiha brothers shared.
What was that awesome dragon jutsu Kabuto used; was it mad eout of water, I don't get it? What was that sphere the dragon was holding in which light shined from? Also, are you saying if Kabuto didn't attain Suigetsu's ability, that his own sage jutsu would work against him?
This fight is pretty awesome so far, from both sides!
