User blog comment:Optic Lens/A new crew member/@comment-4623405-20200407191023

I think most people want to see Carrot as a new permanent crew member, and currently she is the most likely person to join. Also with the addition of Jinbei we know it's possible for almost anyone to join. Before that the new crew members were always people who were introduced in the arc or a short time before. But Jinbei has been around for so many years before even giving the promise to join.

Also ... don't forget that the former shichibukai are now mere pirates again. Maybe there is a potential new crew member in that group?
