What's going to happen to Bianca? I know that she choose to be reborn. Do you think that we will see her again in the Heroes of Olympus series? I have a theory. We already know that Nico is captured by Gaea and is in Rome. Nico might get tricked into helping Gaea to get Bianca back since he cared a lot about her. I have nothing against Nico but this is just my prediction. What do you think?
