what do you mean pointed out again and again? Sasha is the one who draws attention to it actively.
Yes Leia wears them in WiaB; which is 19 years in the past at a minimum, so they if they ARE the original ones, and not similar or copies, would be an heirloom, regardless of actual monetary value. assuming they are actually silver or platinum and not steel... that would be quite the gift to an unknown little girl who is crying.
now explain why the ice queen would've given one of them to a crying redhead...
the current Leia would NEVER do that...
looking forward to her character evolving, among other things involving Leia
Bro the explanation is obviously that Nami is not a unknown girl to Leia, which isnt really a secret considering Katie Zane visited the book club because she was aware of Nami attending.
There are OBVIOUS connections between Nika, Nami and the Zane's, maybe they are related, maybe not but there are connections as the bookclub proved but even before that it was already known that Nojiko worked for Scarlett Zane and so on.
There is a reason why Leia gave Sasha and Nami an earring each (or made someone else gave the earrings to them) we just dont know what it is. It could be that they are both daughters of William and the earrings are a sign of Zane protection as they dont wear the Surname, or its something else but there will be a reason. And the reason obviously wont be related to the monetary worth of the earrings.
The current Leia hasnt reconciled with willy yet and doesnt have a Legacy yet, shes bound to change and i at least can imagine her as a "godmother" of the Zane "clan" who takes care in some distant ways for the offspring of her family but we will see.
But ocean doesnt keep pointing out the earrings multiple times in sg and wiab just to reveal at some point: yo btw these are cheap copies from china, no meaning whatsoever
