@Ninja of War Bullshit. Itachi's Crow could only use the tech once every 10 years with the context being B asking why Itachi didn't use it on Sasuke before(hint hint even at the Uchiha Massacre which was about 10 years before hand, the crow had Shisui's eye) so therefor this is referring to the Crow. Shisui wasn't much older than Itachi(3 or 4 years from what Seelentau has put together) and he awakened his Mangekyo after becoming a Genin, it is literally impossible for Shisui to know anything about the tech if he could only use it every 10 years per eye. Use some logic.
