Sorry if this has been discussed to death already (I don't want to read through dozens of pages.), but at the start of this arc, I was sort of hoping Rebecca would join, after her past came out and her relationship with the Toy Soldier guy she seemed to be in a bit of a Vivi position so I began to doubt it, and now the situation with Sabo basically utterly killed off any hope I had for her.
Now I'm wondering if there will be any "new nakama" at all, I was assuming there might be ten because of the ten on Blackbeard's crew, but now I'm not so sure, I just hope if they do get another member that it's a female and NO NOT JUST FOR FANSERVICE, I usually prefer strong, interesting female characters, but my hopes for that are going down recently unless Big Mom joins, anything but Kinemon or Sabo please!
In the past I hoped for Perona which quickly got shot down (She doesn't have the "sad past" or anything.), Bonney seems unlikely, and Monet is most likely dead (Although considering its One Piece I won't be 100% convinced until I see somebody with the Snow fruit.)
So basically now my only hope is Three-Eyed Girl.
