[ Voice | Private to Kakashi]
[Kakashi may have noticed, should Sasuke's video take in more of the surrounding area that Itachi is sitting right there. And he's been listening to all of Sasuke's portion of this conversation.]
If you be so kind, Kakashi-san...stop making assumptions and using them to further aggravate situation.
[Because he can tell Sasuke is becoming too worked up by how insistent he is being with him. He would rather not know what Kakashi has been saying to him.]
