Right now, I am pretty sure Oda is going to write one (or several) scabbard's deaths the same way he wrote Ace's.Someone dies (Ace,Kin) while someone supposed to be dead actually lives on (Sabo, Pedro).
Why on Earth do you think Base Primebeard = Garp? What justifies giving Base Primebeard casual mountain level DC? How does it even make sense considering DFless fighters like Roger and Garp were his match? How does it make sense considering he had the literal strongest Paramecia in the series?!?!
