... oh! I think I saw someone like that on the platform. Or at least she said she was a whale. I'd never met one of my Lord Uncle Poseidon's creatures before. Do they all talk?

[He seems to take most of her advice reasonably well, although there is one thing that's been bothering him through all this.]

But it seems like a few people do know about several of the things from my world. Like Father, Hades, and the Underworld. And I've even met a different version of... someone I know from home. It's not her, it's definitely not her, but the similarities are too much to ignore. Can different worlds all be so similar like that?
