Annabeth had guessed that the return of Athena Parthenos might cure Athena herself and completely rip her Greek and Roman form apart. If Athena can finally get out of that schizoprenia thing, maybe she will be able to help Annabeth  and the others in winnig the battle against Gaea.

^My opinion.

The giants could only be defeated with a hero and a god working together.
