Let me get this straight:

Percy and Annabeth journey Tartarus to close the doors of death on their side, while the others journey to epirus to close the doors on their side.

After several obstacles, Percy and Annabeth (hypothetically) close the doors of death on their side, while the others close the doors of death on their side too. Jason and the others either escape or get captured. Percy and Annabeth are stuck in Tartarus (for the time being), even after closing the doors.

Why does anybody have to stay back to close the doors of death? (read the situation carefully then reply)
