"I see what's going on here." face. xD
SPOILER ALERT!!! If you havent watched the movie and don't want me to spoil some scenes for you,STOP RIGHT THERE.
I'm proud of Sakura and Hinata. They will never give up,and I'm glad that Sakura's is helping Naruto and Hinata.She'll support them till the very end. And I just remembered what Naruto said to Sakura at one point during the movie. "I owe you a big time Sakura-chan"or something along those lines.
I suppose she requested to be a godmother to their children,and later on,she's Hinata's MAID OF HONOR. ^^ So NaruHina lovers and Sakura haters,by your standards,I think Sakura "finally"did something useful. Her practising in beating and calling Naruto stupid paid off,and she encouraged Hinata to be straightforward and not be shy,cuz that won't get her anywhere.
