Crocus being Rodger Dr explains why he is shown suggesting Rodger against Booze.
We also have Scopper Gaban smiling in the background, there are many panels, nw he is always shown to be with Rodger and is imp crewmate. I hope in other panels we get to see him say something.
Also like others pointed out. Oda is keeping Oden identity a secret, which further strengthens the notion that he actually be alive in the story. But that would cause problems with Zoro, who got his Enma sword so dunno.
Anyway, hyped bout what happened with the alliance previos day.
