I think each character's "crowning moment" for lack of a better term, will happen during their POV. By crowning moment, I mean their greatest achievment in the war against Gaea. This makes snese because we would want to see what's going on in their head during it. However, I don't think there will be 7 POVs in the 5th book. So, the only logical next step is for some characters crowning moment to happen in HoH. Also, I think Annabeth's has already happened, which could mean she won't have another POV. The POVs in HoH will be whoever's greatest accomplishment is needed. Because of this, the POVs are not nescasarily the Romans. I think the last book will have Percy, Jason, a Greek and a Roman. So, that means in HoH, Jason will probably have a POV and 2 others.
