Naruto Chap 439 sudden twist=P

Well...when most of us might have forgotten that naruto is the 4th hokage's son(previously a pic show the 4th hokage with naruto's mom=O). And the manga itself is at a climax with naruto becoming a 6 tail fox due to the anger...of watching hinata getting..."killed?" after confessing to him...yay hinata..>.<

I dun think anyone expect the 4th hokage to suddenly jump out and save naruto..as well as naruto transforming in to the 9 tail(Kyuubi)<----currently 8..>.<
A decent twist i must say...i wan more...roar..>.<
