obviously Elisa told Matt about many of the World Tour adventures (i.e. Hunters Moon- Easter Island Statues) did she tell him about the New Olympians? did she tell any other humans? did Goliath and co. tell the trio and Hudson about the New Olympians?
My guess is that Elisa told Matt some of their adventures, but not everyone. She probably left out the New Olympians as (a) not her secret to reveal and (b) not the most fun adventure for her.
But I'm guessing that either Goliath or Angela eventually told Hudson and the Trio EVERYTHING.
