I hope it is Annabeth, but if it turns out to be another character introduced later then that would be fine too. However, I'm just pointing out that there is room for doubt and that Annabeth doesn't have to be the 7th based on her being a narrator, as there is also evidence suggesting that she isn't the seventh
