I don't get this: why should one stay back in Tartarus to close the Doors Of Death? Rick Riordan will definitely allow Percy and Annabeth to escape Tartarus once they close the doors on the tartarus side. Also Percy can't die in Tartarus 'cause even Death does not linger near the pit. So most likely Percy can be (god forbid) tortured or driven insane (least likely). What I think is that towards the end of the HoH, Percy and Annabeth would end up being seriously experienced in fighting monsters and become the first demigods to successfully survive Tartarus. Then the 7 demigods may stand a chance against Gaia.
