No, definitely not right. But a lot more understandable now. Oh God, how long till we get Arlong/Hancock doujin? They COULD have known each other back then...

Hancock as an ally now set my wheels turning. She's been summoned to Ace's execution...who's to say that maybe SHE will rescue him?

Oh, and Hancock and Hachi could potentially get Luffy in Jinbei's good graces (given what we know now, Hancock may have known Jinbei before they became Shichibukai).
