Itachi’s Expectations

"Forgive me, Sasuke. Next time, for sure. Besides, Shisui is actually even stronger than I am. I was thinking that you might as well go to Shisui for a few days of special training. After all, Shisui knows most of what I know. When I was your age, I also gradually became stronger through Shisui's guidance." Itachi had great faith in both Shisui's strength and his ability to teach others. After all, Shisui had taught him before.
