@Monkey:
Your theory is false, otherwise Sabo wouldn't have placed the cups at Ace's grave.
Did anyone ever confirm that Sabo was the one that put them there in the first place? This theory is not what I truly believe; because I for one think the he is alive as Sabo. I only came up with this in the event that 'Sabo' is confirmed dead but may still be alive under a different persona. So unless you and Oda share notes or something haha…saying a theory is 'false' without concrete evidence which suggests otherwise; doesn't seem right to me. (btw i'm not saying its 'true' either) Theories are all just Speculation.
