"Itachi will know because of the Sharingan"

What kind of logic is that? Kakashi couldn't tell whenever Obito was intangible even with Obito's Sharingan, lmfao, and didn't even know the eyes were linked for the longest time. Itachi's Sharingan won't tell him anything about Obito being tangible or intangible. And I did read your post. You didn't even reply to my entire post and I explained it in a very reasonable way, explaining how Kamui would be effective against preventing Menma from being caught in his Genjutsu as well as why Sasuke and Itachi don't share the same blood.

There's nothing preventing Menma from sneaking up on Itachi from the ground while possessed by Obito and having his Sharingan. Obito sneaked up on Fuu and Torune like it was nothing and they were quite capable.
