On my second read through I noticed that on page 8 that the Hyuga flame symbol appears (the symbol that was on Hinata's shoulder during the Chunin exams). It appears in the top left panel the shows Sasuke taking off his cloak, and it is in the top left of that panel. Also might as well point out that the Kumogakure symbol also seems to be there, but it is being cut in half by what is probably a Rinnegan looking symbol.
I found this interesting so I'm wondering what does everyone else make of this?!
