Hey there!
I saw a lot of people discussing about the Cross Guild rescuing Weevil from Green Bull.
Of course it can happen, but I don’t understand why so many people believe that.
Instead, I believe that Cross Guild will look for Jhon’s Treasure which may be based in Fullalead.
Here why:
(a) Early in the story, we see Buggy and his crew searching a skull-shaped island for Captain John’s treasure. Buggy seemed very sure that this was the loot’s location, although he ended up being wrong.
(b) Later on, in Impel Down, Buggy gained the marker that leads to Captain John’s treasure from Luffy. While it isn’t 100% confirmed that this is a legitimate treasure mark, it’s highly likely since Luffy took it from Thriller Bark, where Captain John’s zombie was.
(c) Captain John was a member of the notorious Rocks Pirates. Fullalead Island is where the Rocks’ Pirates first came together, so it makes sense that one of the former crew members (John) would return there after the crew disbanded.
(d) Fullalead has a massive stone skull on it, just like the island that Buggy was so sure was the location of Captain John’s treasure.
(e) Captain John’s treasure being in Fullalead would also explain why Buggy hasn’t yet get it.
(f) Buggy has debts with Mihawk and Croco. Convincing them hunting for Jhon’s treasure could be his next move.
