First thanks to all the providers!
Next, it really feels good to see the Buggy Crew again. I wonder where they met Ace and how exactly they became friends. And you could call ID the hell on OP-Earth.
I think that Hancock tried to teach Luffy some bit Haki. Maybe it's just wishful thinking but how could they better spend those four and a half days aside from five meals a day?
And I really can't see Luffy helping Ace all on his own. An involuntary teamup with Buggy would be nice. But I think there's no way that the three of them could escape even if Whitebeard was attacking meanwhile. I suppose the other SHs won't get there in time and how should they even know Luffy is there? Imo, there has to be a strong third-party character like maybe Dragon so that Luffy, Buggy and Ace can escape.
