Re: Naruto 453 spoiler/Prediction thread.
Guys, I'm still looking for the source.
As far as I remember, it mentioned that Danzou was betrayed. So it should be someone from inside root.
And it did not mention why Kakashi needs to wear an Anbu mask to go after Danzou. It is my own understanding that Danzou, after being betrayed, was running away. Kakashi was going after a runaway Danzou.
I'll come back to you when I found the source.
