@Bipedmango - here's a little recap...

Before being killed by Sasuke, alive Itachi programs Shisui's eye in his crow and sneaks it down Naruto's stomach. The Eye is programmed to cast Koto in that person which has Itachi's eyes and convince them to protect Konoha. Why would he do that? Because he correctly deduced that Sasuke would take his eyes once he killed him, so when EMS Sasuke eventually met Naruto, the crow would surface and cast Koto on him and make him a good guy. Unfortunately, Naruto didn't get to meet Sasuke by the time the eyes activated and thus the Koto was "wasted" on Itachi. Did that answer your question?
