Dredging up an older post here, and with a sizeable SPOILER question.
You've been warned.................
How the hell does Hercules and whichever one becomes Ulysses mother (can't remember which) know that he was their son? It's mentioned at the end that they knew who he was, but how do they know in the first place? I reread the book recently and it still wasn't any clearer to me.
