It's also possible that they do eventually make it to CHB, but only after the gods alter their memories with the mist. I'm thinking maybe every now and then, say a child of Ares, would show up at CHB with alot of skill in the orderly Roman swordplay. They wouldn't exactly question him too much, as both Luke and Percy were also naturals at sword play.
