Great chapter but the title was very subtle if you hadn't read the previous chapters (I think that's something called "plot"...). Understanding Kabuto is key to understanding how the jutsu works. Interestingly enough, Itachi has been speaking in a more upfront and understandable manner, which I think is very important.
Sasuke also is coming out of his "edo tensei," so to speak. As many younger siblings do, they idolize and worship their elder siblings and mistakenly think they are "perfection," when, in fact, they are human beings capable of failure. Itachi's acknowledgment of himself in the light of truth, I think, is what is going to bring Sasuke back to reality, if it hasn't already. Itachi has had a lot to say to Sasuke in merely demonstrating this jutsu and explaining the "hows and whys." He has been, very skillfully, been applying these concepts to himself and his life and showing Sasuke that there are other options; other choices to make. Itachi also explained some of his failures - including dismissing Sasuke as a mere younger brother who needed to be protected from harm/the shinobi "system." He also said something key: he didn't trust Sasuke's strength and abilities. Itachi may have loved Sasuke but to not trust the abilities of your younger sibling or someone close to you is, as was being pointed out in this chapter, arrogance. Perhaps Sasuke may think back to how HE had not acknowledged the abilities of others closest to him - ESPECIALLY Naruto.
Then there's Kabuto. His admission of wanting acknowledgment is repeating a theme that has been a hallmark to this manga. The innate desire of everyone to be acknowledged for something is now front and center yet again. But the ones who have openly expressed this desire...? Hmmm: Yondaime Hokage, his son (Naruto), Kabuto, Sasuke...the list goes on. However, it is how they chose to fight for that acknowledgment that makes things very intriguing. Kabuto and Sasuke were "lost" and had no clue as to who they truly were and saw themselves through the identities of others. Yondaime Hokage and his son, Naruto, had very clear understandings of themselves and their abilities - even if others doubted them. However, they did not rely on obtaining the identity of another to define who they were. They were "actions speak louder" types, which is the message that Kishi wants to send - through Itachi's words and his actions in his "undead" state. Unfortunately for all of us, that means Itachi's time in this manga is almost done as once he releases the edo tensei...yeah, better get your kleenex out.
I'm anxious to see what Sasuke does once the edo tensei is released...
