I was doing a little digging into the whole suit cards that the DD pirates seem to follow and found some pretty cool things that might help us predict the forth coming chapters.
Diamond: diamante: club: fire: 4: blue
Heart: corazón: cups: water: 2: red
Clover/Club: trébol: coin: earth: 3: green
Spade: pala: sword: air: 1: black
^ That is an amazing find there xioa, works perfectly with what we've seen so far on Dofla's top pirates.
The fire part with Diamante worries me. This hints that he might eat Ace's fruit.
As for the hearts thing being corazon, its not been proven that Dofla won't replace Law's seat as the heart with someone else.
