Please not that this comment (and a lot of the comments on this page) was made before the release of The Son of Neptune, meaning we didnt know who the child Hades, Poseidon, Ares, or Athena were. After Hazel was named a child of Hades/Pluto, the thought of Bianca being the last has pretty much disappeared.
