It is said that the Romans are going to attack Camp Half-Blood around August 1st when the giants attack the old Mount Olympus in Greece and Gaea rises. I do believe that the Athena Parthenos will stop the Greek vs Roman fighting but that will be last minute as usual, then Zeus will see the Greeks and Romans getting along and open Olympus. Then one of the Gods will teleport both the Greeks and Romans to the old Mount Olympus and the battle will start. The crew on the Argo II won't wait a month for the Romans to help them close the Doors of Death they will go to the House of Hades as fast as possible to save Percy and Annabeth.
