In a couple of chapters (about 3 or 4) we'll see Crocus again! The legendary shipdoctor of the Roger Pirates! What's even better, we'll the Laboon again. And since the Marines finally took notice of Brook really being a crewmember, he'll be in the papers. So, what will their (Crocus' and Laboon's) reaction be like?
And since we're at it, who do you really want to see after the timeskip?
