Yes, that's what is mentioned in Lost Hero. But Gods had no problem in helping their different kids so far. Why are they all of a sudden having trouble with their personalities?

I thought for awhile that Juno/Hera caused this. Zeus closed Olympus under Khione's influence and partly cause he was pissed that Percy was more righteous than him. But than, Hera entangled two camps and split personalities curse kicked in. Athena, being the most changed and insulted God of all, was forced again to battle her despicable Roman side that no one respected. But  Poseidon and Dionysis (and Hermes, i think) said Gods can be at dozens of places at the same time. That they have no problem in managing their many aspects and personalities. So why are they having problem with their Roman side? Maybe because Athena is influencing other gods, and not Khione?

My wild guess is that only Athena/Minerva cannot suffer her Roman side, while other Gods are having no trouble with it. Her statue was stolen the day Athens was razed by Romans. All Gods were transformed and their temples were only "fixed" for Roman use, but Athena was the Great Protector of all Greeks. She was the symbol of Greek might, and she had most beautifull temples and greatest statues, beside Zeus. Only, the greatest Goddess of Greeks had no statue of her(it was stolen by Arachne). So Romans didn't know about her importance and gave her only a small role in their pantheon. Which is wierd, really. Of all the Gods, Athena should have been the least changed God in Rome. She was the Goddess of wisdom and battle strategy, the mother of democracy! Exactly what Romans respected. But without her statue, they didn't know about that. So, retrieved statue of Athena Parthenos, should right the wrongs done to her. Restoring the Statue may cause Minerva to take her rightfull place in Roman Pantheon, and serene Athena/Minerva may stop influencing Gods and stop the war between Half Blood and Jupiter.

Sorry for the text wall. I've been thinking a lot about this matter.
