To begin with, you're wrong, Brooke wasn't looking for thriller bark, why exactly would he have do so, he learned of it's existence when THEY found him 5 years ago and stole his shadow, you're confusing two story, he told himself his death and his shadow are two unrelated stories.
Ah, my mistake, I thought you were referring to the wandering he did to find Thriller Bark, not the wandering he did to find his body. A stupid mistake on my part, sorry.
Well then please feel free to read chapters 442 and 443 if you don't remember, cause luffy proposed and brooke accepted, he then declined in the next chapter because his missing shadow would prevent him from doing so (and please, at least don't contradict yourself by saying the first time he wasn't thinking about laboon).
Yes, you're right, he accepted, then he left because he needed to reclaim his shadow. And yes, you're right, he was certainly thinking of Laboon then. Perhaps that bit about him having to fulfill the whole promise was true. Or maybe he was just gonna join them for a while because he wanted company. He can't have intended to join permanently, because he couldn't leave the Florian Triangle, and he didn't want their help getting his shadow back, he told them not to follow him into Thriller Bark. It's possible, but he may just have been saying he'd join temporarily for the sake of companionship.
So I ask you again, when exactly did it happened that the most dangerous see in the whole world became something so ordinary one could cross it on foot (no reference to mihawk or aokiji, unless you wanna compare a shichibukai and an admiral to brooke, and I wouldn't follow you there... )
I'm not saying he's on the level of an Admiral or a Shichibukai, but he IS pretty strong. His invulnerability would make him at least a middle-class Straw Hat (not the Monster Trio, but not too weak, basically Robin, Franky, and maybe Chopper.) And again, it would be dangerous. I never said he'd cross it on foot. Maybe he'd get a boat, he has his own, and there are certainly some floating around the Florian Triangle. Maybe he'll take over Thriller Bark. I'm not saying it's ordinary. But the fact is, the weather issue wouldn't hurt him, he doesn't need to stop at any island for supplies, and for all we know, Thriller Bark has a giant collection of Log and Eternal Posts. They've been stealing stuff off of ships for about 10 years now, and they'd certainly take things as valuable as Posts. He could get a post set for Whiskery Peak or something, and from there to Reverse Mountain isn't so far. My point is, there are ways to make it work.
Cause for now he doesn't even know what happened to laboon, but luffy will tell him he's still waiting, so sorry but I don't see where the "CAN'T wait" is coming from... I also agree with weixiaobao that brooke could join the mugiwaras for that reason.
Human psychology. After waiting for something for a long time, people get impatient and don't want to wait any longer. Only people who don't feel as stressed as the one waiting say "You've waited this long, you can wait a bit longer". And I DID acknowledge that weixiaobao may be correct. He's got the best reason for Brooks joining I've seen yet, and the only one I can't explain away that well, at least to myself.
As for not fitting in with the crew, instead of just saying brooke's attitude don't fit in, could you please enlighten us a little on what you mean... cause till now we have a stupid captain, a lazy swordman, a love cook, an overly sensitive cyborg... so why wouldn't an impolite gentlemen fit in exactly...
I dunno, I just don't feel that he belongs with them. I can't really explain why, I just don't get the feeling that he'd fit well with them. What job could he fill, anyway? And even if he could fill a job, I don't see him fitting in.
And vivi dream was achieved when she left the mugiwaras, she restored alabasta, now she had a new dream she couldn't fulfilled with them, that's why she didn't join in the end... but as I said, joining the mugiwaras isn't in the way of his dream at all, they could actually help him fulfill it...
Again, that is weixiaobao's point, and I acknowledged that it may prove true.
Anyway, as Franky stated, there ain't that many people that would accept him, but with luffy he already found people that want him to join them, so I just see many reason why he could join, no reason at all why he shouldn't or couldn't.
True, he may still need the companionship. But from the fact that he's continued to chase his dream despite that for so long, I think that he's willing to forgo any other companionship to be with Laboon. (I said above that he may only have intended to stay with the Straw Hats TEMPORARILY. Though if he has the chance, he may NOT wish to forgo that companionship if he doesn't have to, and weixiaobao's point may prove true, in which case Brook will still need nakama to fulfill the full dream and cross the Grand Line.
