actually Nico having a POV for me is, well, just as expected, the son of hades only one of his child who can interact with him, since the other is supposed to be dead, and trust me on this is almost a given hades will appear at one point or another in the story, they literally going to his domain and he rounds the number of POV nicely so that we have the same as the last one without having one from nowhere, like reyna (really what's suppose to happen here) and acting as a drama preserving handicap (since that way we won't know what's happening to percy and annabeth until the end of the book, and we will only get glimpses, I can imagine rick laughing as he writes scenes like that)
