Sakura is an idiot not only because she ran up to Naruto when it was obvious that just getting close to him, much less hugging him which I'm sure she was going to do, is dangerous. Again ninjas aren't supposed to be idiots I mean if Yamato didn't save her again she would have just stood there looking at Naruto and got cut in half which would have been funny as hell.
Yamato's sealing technique was weird I don't quite understand the mechanics but it appears he was pumping his own chakra into Naruto in order to suppress the Kyuubi's. I don't think the pillars were there simply to prevent the Kyuubi from running away because it wasn't even attempting to run away and if it was those certainly wouldn't have stopped it. I don't think Naruto can even walk in that form much less run away. The spikes won't hurt him and those little wood pillars certainly couldn't stop him, I think there is more to it.
The way they did it was confusing though and I don't understand why he would need to touch it, think about if this was used on the Kyuubi that would mean that he would have to actually make direct contact with it, thats suicide.
Kabuto = Awesome. I never even thought people could heal like that I thought it was always a close range thing but he did it from a distance and it was really fast too and even so he still said it took longer than he thought it would. I think that may be because the wound was caused by the Kyuubi's chakra, I mean when Oro touched it with the snakes they immediately caught fire. If there is a god in Naruto, he should get rid of Sakura because Kishi ain't gonna do it.
