1.) If Konohomaru fights Pein, he dies. Regarding Enma, I don't know where Konohomaru would get the contract unless it was left to him. Even if he has the contract, I believe that summoning him requires Hokage level skills/chakra. Naruto could summon Gamabunta at that level because he could invoke the power of the Kyuubi chakra. He was also schooled by Jiraiya, and Ebisu is not Jiraiya.
2.) I think we haven't seen Kakashi for this episode because he's not really a factor, and he is a cliff-hanger. We will talk about Kakashi every week until we see him die or live on. I expect him to finish his vision/dream with the next seen showing one of Kytsui's slugs healing him. If he lives, is what he's experiencing now a near death experience or just a dream?
3.) I said this earlier, but it bears a re-mentioning. I'm concerned about the psyche of Pein and Konan if they fail. Pein is a "god" and Konan is an "angel." Pein has never lost and cannot lose, but if he does, he is mortal and she is just his support. Just a prediction if Pein loses. *Conspiracy theory...Madara sent Pein to Konoha to fail and shatter his self-image since he and Madara have different visions of what to do with the Bijou's, thus reducing a threat.
4.) Naruto has already learned and improved his taijutsu by learning the toad kata, which I believe is toad martial arts. We saw this in the Manga where Naruto fought with Fukasaku in sage mode. How this translates to his clones ability I don't know. What would be the most practical is for him to generate clones and see if he can master having them fight somehow.
5.) Regarding Naruto vs. Pein right now. If he can master fusion, then I think he's ready to partake (not defeat Pein by himself already). However, Pein needs to shift priority from Naruto (unless he shows) to protecting his secret. Kill Shizune, Ino's father, Choji, etc.
6.) The spoiler said that the code on Fukasaku's back is for Naruto, so why were there all these issues on decoding the secret? Is the code more personal, like his father, his destiny, kekkei genkei, controlling the Kyuubi? Please speculate!
I've written too much that it rambles.
