Well that's highly unlikely. Iapetus wouldn't give such a powerful weapon back to Ethan once he had it. And I mean the gods don't have to physicaly go into Tartarus all they have to do is agree to bring Percy and Annabeth back then combine their power to retrive them. I mean the gods have each brought someone back to life in Mythology.
