Seriously? -.- I'm pretty sure it's just the highlighted chakra... I doubt that the author was just showing what Sasuke could guess from what was there. He also sees the other snakes from afar and behind the stones.
Yeah, well, Kishimoto is also inconsistent. So here I am, telling you, that the Sharingan cannot do that. Itachi even said they were seeing chakra, not necessary the snakes beyond the pillars. So let's assume you're right: How does Katsu see chakra through chakra? Karela's earth prison is a jutsu, jutsu's use chakra ...and beyond that, how did you follow him underground and determine he was going for you? Byakugan could arguably do it, but that's NOT what the Sharingan is known for and in one vague instance where Itachi and Sasuke locate Kabuto through chakra emanating throughout the cave isn't good enough evidence.
And just to make sure I was right because the manga isn't as detailed I looked it up just for you, the anime fight CLEARLY SHOWS that Itachi and Sasuke both see CHAKRA, not directly through the pillars themselves. So I was right; us seeing through the pillars in the manga was so the reader was able to better see what Itachi and Sasuke were seeing because there's NO COLOR in the manga. They're locating chakra throughout the cave, they didn't find the snakes on their own by seeing through walls. Want proof?
