"It isn't like I hate you or anything!" - Fujitora's reaction to that, epic. I love how the only other person Luffy has said that too has been Smoker, and Smoker has more or less the same reaction. He blushed for a second, and wondered just what the hell kind of person Luffy is. I knew all along that Fuji was holding a piece of himself back, but his sentiments showed that he actually respects Luffy a lot, and I can't wait to see the next chapter of their relatoinship unfold. I also really liked how we got to see his Kenbunshoku haki at work, and its crazy just how well he actually CAN see without his eyes. Oda seemed to be foreshadowing that he might actually tell us at some point how he ended up bliind....

As far as the alliance goes, it all makes perfect sense to me. Luffy is going to say yes in a very comically unexpected way probably, but he WILL say yes. Here are my main reasons:

1) The Luffy-Law Alliance isnt forever. Luffy and Law are going to be great rivals, and even better friends, but they're both way too important to the storyline to ever subordinate themselves to each other. I actually think Law will die at some point, but I think he'll have his own agenda too after this Kaido business is finished. Luffy needs people aside from his main crew that are going to be ride or die, as theres too many things going on in the New World at once now that are going to affect his future in some kind of way. There are 4 Yonko out there all with crews just as big as his has just gotten if not bigger, and a crew of 9-10 (Law's crew appears to be about the same size) can't compete with that, no matter WHAT the circumstances are.

2) The world is going to hear about this. Luffy needs to establish himself as a FORCE in the New World, and nothing says that quite like a monstrous crew of several people that are fairly reputable in their own right. Its as Fuji said, there couldn't be a bigger bullseye on Luffy right now, and "living hell" is an understatement as a description of whats to come for him now. If the RIGHT person shows up to face them at the WRONG time, Saobody could easily happen all over again.

3) The fated world-emcompassing final battle of the series. Luffy will eventually have pretty much the entire world minus the WG and its allies on his side, so it really shouldn't surprise anyone that you're getting a taste now. Luffy's ability to amass allies  in large quantities has been foreshadowed since God knows when. In all honesty, I believe Kaido will be one of those allies. Kaido wants this war to happen sooner than later, and in all honesty I believe Kaido's intentions to were to increase the scale of the war at Marineford, not necessary take Whitebeard down. Shanks wanted the war over, so that's why he intercepted him. Kaido said "that damn Whitebeard's gone and done it" because he spilled the beans about One Piece existing FORREAL, and there being a person who's going to carry all those years of history on his back into the final war. Through their eventual confrontation, Kaido will come to respect Luffy (Luffy obviously wont kill him) and realize that he is this fated person of "prophecy". Having so many people in so many places is realistically the only way Luffy will be able to start spreading these seeds of revolution.
