Now lets all take a minute to remember the events of the Lightning theif. In the story someone stayed behind because they only had three pearls and there were four people.

Percy got his mother back because Hades was generous. Also in the movie, Zeus was shown to be forgiving enough and generous enough to bring her back to life.

Now what if Nico does become the person to give himself up to save the world and the quest to stop Gaea.

I know everyone will be sad and depressed due to the fact that he had to give his own life. But may be Percy could have a plan to make sure they do defeat the Gigantes and save the world in order to redeem a wish from Zeus. This time he could ask him to bring Nico back from Tartarus.

We all know that the Gods have powers to send people to Tartarus, but do they have the powers to bring them back? Not one has been mentioned to have this power, but I'm just wondering would they have that power?
