User blog comment:SonOfZeus1200/The Camp Half-Blood & Kane Chronicles Series will collide!/@comment-207.74.86.35-20120508101552

Through the whole kane and Heroes of Olympus series' I just expected that the hints were maybe suggesting some small crossover within the series, like Percy spotted someone who he describes in way that seems like Carter or Sadie doing something magical but is too caught up with something to stop. (like being chased by a monster, or giant)
