What I think will happen regarding the Romans vs. The Greeks scenario is that obviously the seven will close the doors of death and make it back to camp half-blood before the Romans invade. And when the Romans arrive. Annabeth will give Reyna an ultimatum that they could fight to the death and if Annabeth wins the Romans will go peacefully and if Reyna wins the Greeks will surrender. So Annabeth and Reyna start fighting and things don't look so good for Annabeth but right when you think Reyna is going to shove her javelin through Annabeths chest. Reyna gives Annabeth her hand to help her up and then the book ends.
