I don't care what anyone says, Minato is the BOMB. WOW!
I was not expecting that at all. I was still thinking Minato and the others will arrive 1 mabe 2 chapters to come. I was expecting Killer Bee's last stand. ending with Hachibi giving his chakra to Naruto, but.....Minato just came in there and showed why he's probably the strongest/deadliest/smartest Shinbi ever.
Minato was able to teleport to Naruto because he may have left his Mark on Naruto's Bijuu Seal, probably out of habit.
Thois chapter could have been entitled, Kakashi's Talk-No-Jutsu technique. Sure it's very week next to an expert like Naruto's TNJ.
