I'm sorry but those links proved nt at all.
Fact there are two ways ppl can perceive wat happened;
1) Oro didnt 2 fukks about the sword, why? because those kind of attacks wouldnt affect him and he was in a snakes mouth. Why would you try to dodge an attack that has no affect on you. Also, this is Oro, he's careless and would rather take a hit than dodge it.
2) ppl can assume that the sword is fast and just caught both Oro and Nagato
However, based off wat we've seen it would be smarter to assume that neither Oro and Nagato tried to dodge the sword because one couldnt and the other didnt need to (as he thought). This wouldnt be able to judge the speed of the sword, thus it cant be up for debate becuase no one has tried to avoid it.
I see you like to attempt to analyze stuff beyond what is there. I'll give one too, I see you have Orochimaru in both your signature and your avatar, and are currently defending Orochimaru in an Itachi thread because Orochimaru just so happened to be one of the two that Itachi chose to seal, otherwise I think you'd say the opposite. Look I get it.. Orochimaru is cool but you can't just ignore facts here (Well I guess you can since you're currently doing just that) but what we can take from that manga chapter is Orochimaru was busy bragging about his victory before anything even happened, so busy in fact he had his eyes on Itachi the whole time to make a point, yet somehow he magically got cut off mid sentence with a surprised look on his face which indicates he had
no clue what had just happened, otherwise he'd have looked at the sword coming at him and laughed before it hit him, not have a surprised look that he got stabbed and then proceed to laugh that he got stabbed, that doesn't add up, if he knew it was coming at him and thought it wouldn't hurt him, he'd have laughed before it even stabbed him and then continued to laugh in the next image when it was shown he was stabbed, he wouldn't give the expression "What the... did I just.. get... stabbed before I could finish my next word in the sentence?" Which is exactly what he did, so he did not see it coming, and could not avoid it if he wanted to since he didn't know it was going to stab him.
Simple.
