Ok ok I know people are wondering do they even know eachother there is a posbility though in Naruto Shippuden Movie 2:Bonds......
When Sasuke Throws a little girl to the boat where Hinata and other villagers need to escape from the castle or floating object whatever it is, Hinata sees Sasuke and shouts Sasuke but not the loud and is happy so yeah that might explain a little that Hinata might know Sasuke but it could me that she probably might see him and remebered his name after all they where in the same class together (watch episode 1 if you haven't noticed) so yeah maybe just maybe SasuHina will happen after all
