* Genjutsu from Itachi .
*Ten wheel eyes. I think this refers to Danzo's Sharingan. There are 10 of them. 5 on the outside of his arm and 5 on the inside.
*Explaination of danzou's technique. The persons life is tied to the Sharingan arms through the chakra. So its a life exchange jutsu. I think its sort of like Kakuzu execpt with eyes.
*Something about frog key and Kyuubi's cage.
