In the Son of Neptune, There's a scene where Mars talks to Frank about his worth relative to the rest of the team and Percy Jackson's fatal flaw. "He's too loyal to his friends. He can't give them up, not for anything. He was told that years ago. And someday soon he's going to face a sacrefice he can't make. Without you Frank - without your sense of duty- he's going to fail. The whole war will go sideways, and Gaea will destroy our world."

I think this is the most reliable and clear peice of foreshadowing for whats going to happen in Blood of Olympus. Frank is going to have to help one of his friends make a sacrefice, Percy Jackson obviously wont stand for this and I predict the two are going to fight.

Neither hero is being decieved or controlled, both is doing what he thinks is right but their priorities are clashing. If Percy Jackson, the hero we've been rooting for since he was 12, emerges victorious the world just might end.
