[ Kakashi can't say that he entirely follows the explanation -- the flower thing doesn't make sense, and neither does the thing about the roots, but he supposes it has something to do with Obito becoming the Jyuubi jinchuuriki (which is what it sounds like, anyway, from the explanation). ]

I had heard that Sasuke was supporting the war effort, and am glad to hear he continued to stand by Naruto's side through this.

[ As for Obito... Kakashi would much rather not talk too much about him if he can. But not talking about it may seem strange, so he adds on -- ]

I'm also glad to hear that you are in the process of neutralizing Obito.

[ If only because that means that Obito won't be able to continue to hurt anyone else. ]
