In Impel Down, Ace stated in referring to he and Luffy, “We both have the blood of world class criminals running through our veins.”
But how did Ace know about Dragon? Dragons family name and heritage was such a secret only 3 people knew without Luffy saying it: Garp (Luffys Grandpa), Sengoku (Garps lifelong friend), and Kuma (Dragons right hand)
So how did Ace know? It’s not like Luffy told him since Luffy didn’t even know. I can’t imagine Garp saying “You think you’re bad, Luffys dad is the worlds worst criminal of this era.” And Sengoku has no reason to tell him.
