You keep saying that Nico's homosexuality is "completely out of place" or that there "were no hints," but that's not true. Throughout the series, Nico had always struggled to have conversations with girls. He had been more comfortable with Percy than anyone else, until around TLO (maybe around the time he discovered his sexuality?). That's when he started becoming slightly awkward around him. There were hints; you just needed to look in the right place.
