So far, it's never been explained if Hades KNOWS a person in his domain until he meets them; he knows a new soul has arrived -- or if one has departed -- but it's never stated if the moment a soul arrives he goes "Oh, so-and-so is here."

This COULD be their first face to face meeting, but Hades already knows of Rumple because, as Cruella says, they "see everything down here".
