@MlgShinobi, so what you're saying is, Itachi inserts a pre-coded Genjutsu that affects them in an instant.

But if that were the case, Itachi shouldn't have been able to speak to Kakashi in Tsukuyomi, because a predetermined Genjutsu that he simply sends out wouldn't have reacted to Kakashi when he was talking. Kakashi said something in Tsukuyomi, then Itachi responded. If all he did was send out a code for pain, then Kakashi would have just been in pain. But the two held a conversation in Tsukuyomi. So Itachi was there, with Kakashi, inflicting the pain. As it went.
