Well, a bit late but here it is…
Basically, my thoughts are the same as I wrote them on the Naruto 455 Spoiler post, especially regarding Sai. I mean, he clearly is starting to show a genuine concern towards Naruto and Sakura – which naturally makes him care about them – and it’s shown in his reaction when he stopped Karui’s punch; Kakashi pointed that out too.
At the end, I do believe that Sai will no longer follow Root/Danzou’s “teachings” and will become “one” of the group.
Talking about Danzou… maybe it’s the angle but it seems as though his right eye (with the sharingan) is higher than his left one… it looks kinda deformed…
