i mean its clear as day who Sakura loves , I mean have seen instances where she is prepared to protect Naruto from Sasuke , like in 632 when they said Sakura was smiling at Sasuke , it looked more like to me that she was looking back to see if Sasuke is trying to attack Naruto . We have nothing to worry about , lets just sit back with our popcorn and cans of Sprite and lets watch how beautifully NS unfolds .
Well, she did only talk to him, which is one thing I noticed. Anyway, yes, it is clear but it's important now she got to realize it herself. She got the taste of Team 7 reunion, including making the parallel of Sannin, so now the real deal is what is her feeling in this situation. Fighting along side with them, it still gave her a bad impression of Sasuke. Not a good sign. In fact, 632 through 644 was the nostalgia trip and when they thought Juubi is gone, it dies off and it starts off with the newcomer of Team 7, Sai. She got her fun with Team 7, but time to be serious. Now, we just have to wait where her "smile" to Sai would mean anything.
