So you think Itachi meant what he said? that him and Kisame both would have died? Itachi wen't to Konoha to check up on his brother, he didn't intend on fighting anyone. If he wanted, he could have killed Kakashi, Asuma, Kuranai, Jiraiya and Sasuke and then captured Naruto, he probably wouldnt even need Kisame. I know Jiraiya is your favourite character and everything but don't be biased. Jiraiya was looking in Itachi's eyes throughout... what is to stop Itachi using Amaterasu or Tsukuyomi instead of wasting it on Sasuke? Jiraiya is strong but you need to realise when a guy is outmatched. And don't underestimate Kisame, I gave Jiraiya the win but at high difficulty.
