I'm not sure - Donna seems to be involved with that organisation, I doubt she isn't, seeing that she is creepy around William, and is still a school counsellor in the rework. But she doesn't have earrings, despite almost certainly being on a mission of some sort. I can believe that the earrings show some affiliation to the group, but I am more inclinded it is Ocean liking the style for that person. Pre rework Leia had them. I think the important earrings are Nami and Sasha's. They are more valuable to decypher the reason. Kelly is dressed in the colours of a nun, with cross earrings - it's almost like Ocean made her a cartoon character.
