Yes, she already has. It was a filler episode. I guess it counts when naruto is fightine pein, too.she goes on a mission with naruto on episode 148-161 or162...175-176,194,182-185...and ....
There never was an episode that they went on a mission in a boat; there was a part in Movie two when Naruto, Hinata, Sakura, and there V.I.P's go on a boat.
yes..on a mission and eating at ichiraku
No, Hinata and Naruto never go out.
yes on missions I'm not sure about when they aren't on a mission
they do never go out
Not yet
No not yet
No, they are not in a relationship
Not yet.
Nope
Naruto currently isn't dating anyone, he has a choice between Sakura and Hinata.
Maybe, there is a hint, when Hinata confesses to Naruto that she loves him in the middle of the fight against Pain.
