I haven't given one thought to what skin color Brooke had. And after reading about this ghetto Brooke stuff….. I still haven't.
In response to what Tony-kun said, As I've said before Brooke might have more weapons on him than a sword. That's why I plan to wait this out. And also, Brooke just might have a dream. Remember, he said something to Franky that made him cry and emotionally touched him. That's a clue, and another reason why I'm going to wait this out.
W don't know if he'll join for sure, but also there's obviously some clues as to whether or not he will join which haven't been revealed yet.
The only theory I persistantly stand behind is that he may be the skeleton of an elderly man.
edit-
think I now know how to describe Brooke's voice from my dream. Does anyone remember when Panchito shot the bullets into the air while singing (yodeling?) in a really high-pitcted voice in The Three Caballeros? That's it.
