I agree...it could have been a last minute addition, though I don't think a gay character is a big deal....I am just of the opinion that we dont know much about Nico to say that his orientation is out of the blue.......there has hardly been any character development for Nico in PJO except perhaps the last few pages of The Titan's Curse and in certain parts of BotL....and again the first few chapters of TLO...after that he mostly vanishes as a character and appears only as a plot device up until the time he is rescued..........HoH is the only book goes into some depth.
