drowning hurts

Naruto was waiting with Sasuke for the rest of team 7 to arrive when the railing on the bridge had collapsed. Naruto had fell into the water beneath because of this, but he couldn't swim. Sasuke had seen this and decided to help but when he got to the blonde his lips we're blue and skin deathly pale. What would he do?

(No character death, no angst and no pairings with sakura ).
This idea for the story is entirely mine.
