Yah I think so. You mean how he was shaded? That definetly seemed weird. I don't think he is going to ichiraku. He might already be heading out to fight Sasuke. Think about, he tells everyone there is no way he can beat him (which Danzo said was false) and then he tells everyone he is heading out to grab some ramen. Maybe he would have told everyone that he was to weak just to completely push the idea that he would beat him on his own out of their minds. It was like everyone behind him watched him walk away. At first i didn't think any special at all about that panel but now that you have drawn attention to it seems like something suspicious is happening.
