Sketchy one
Brooke is some undead (underworld/hell) ability user, he was able to revive himself after he died (continued living, even after death)
It took 10 years for him (his soul/ghost) to locate him body, which was killed by pirates in furian zone.
Even after death. His afro hair remained strong (he's a musician of some sort)
Brooke has no reflection in any mirrors, nor a shadow and disappears when standing out in daylight(?)
A Ghost/Spirit appears in Zoro's room this week.
They head towards an island (ghost/spirit island), but the log doesn't react it.
Brooke explains the reason behind the barrel fireworks, and warns against the Strawhats landing on that ghost island. (The rest is beyond me :/) But of course despite the warnings Luffy still wants to goto the island. -_-;
That's it for this week.
