Have the Avalon travellers mentioned New Olympus to the rest of the clan and other friends (Matt, Elisa's family, so on) or are they under a vow of silence or something?
Elisa's not big on info-sharing, so I doubt she's told anyone.
My initial thought was that Hudson and the Trio would be filled in. But maybe not.
Certainly, no one else has been told.
