If you meant that about Sasuke taking info from Jiraiya by the use of sharingan(not sure if that's what you're referring to) then I would just assume that Sasuke simply didn't know about Itachi's vodka taken by Jiraiya.Originally Posted by Death BOO Z
Sasuke wasn't really befriended with Jiraiya and we were never shown a situation where Jiraiya confesses to Sasuke telling him that he fought his brother and Itachi left a gift for him to examine.
