Now before people start accusing me of extreme fanboyism let me put fears to rest. This is discussion about why I believe Sasuke wants to hold his conversation with the Kage's while viewing the Uchiha tablet. Sasuke may have begun to realize that there are inconsistencies that require further investigation between what the Uchiha tablet says and the real events of the Hokage's recollection. There is something about the Uchiha tablet that Sasuke has caught on to. Something that we as viewers of the story have already caught on to but has not been revealed in the manga by a character. The concept that the Uchiha Tablet was written by the So6P and instructs the viewer on how to progress the Sharingan and use the DNA from his younger sons descendants simply doesn't hold water. By bringing the Hokage back, he has the opportunity to perhaps verify the validity or reveal inconsistencies contained therein. In the absence of an ability to time travel to the tablets creation, he has done the next best thing bring the past to him through Edo Tensei.
