Mayby Naruto's family has a dark secret that the third didnt want to tell Naruto about it yet cause he thinks that Naruto isnt ready for it yet,he is after all just a kid.

Death Boo Z: I like the thougth that someone i Akatsuki is realated to Naruto maybe Itachi is gonna tell Naruto that someone in his group knows his past then Naruto would probaly go with them without a hassle. I really hope this happens.
