Yep I agree completely. I was just arguing against what some people said about how Kakashi must have deduced MS's effects on the eyes based on his experience with S. Therefore, he must have researched or had first-hand experience with MS and its effects on the eyes. After he got owned by Itachi in their last encounter, I would expect that he researched everything known about MS, and that's how he knows more about it, without actually knowing how to do the technique.Originally Posted by XanBcoo
