I don't remember the Kyuubi being so involved in naruto's personal life, he's acting more like an 'evil conciseness' than demon. maybe it's the after affect of dipping to the lake of mirror matches.

even though he's wrong, I still liked Naruto in this chapter, slamming down the kyuubi and calling him gullible is pretty badass. I even liked the flashback, well, parts of it. I liked how Naruto and Sasuke clashed, it showed that Sasuke didn't give a crap for no one, and that's what really hurt Naruto.
