I am actually taking a different tack on this with Gin. I enjoy making up ever more ridiculous things she is doing as 'training exercises' from Hamon Holyfist, she has the Echo, is a member of the Scions, BUT....she doesn't realize that this is extraordinary. She's very much of the if you work hard at it you can do anything mindset, and the thought of possibly being unique has never crossed her mind really. To her of course anyone who is a good adventurer would be invited to the Scions, but maybe they just don't have time to help them out. To her its the same as if someone else said they had a frequent buyers card for her favorite little hole in the wall restaurant, 'oh, you do to? That's great, maybe I'll see you there'.
