I think that the whole Jason vs Percy thing is more of a Camp Jupiter vs Camp Half-Blood omen rather than a major fight between the two. The owl might also represent Annabeth trying to stop them as it stands in the middle of the cover. Anyway, we're pretty much throwing stones in the water for now. The only thing that's clear is that war will break loose between the two camps. Dear Octavian will be busy.
