User blog:TheWiseOne/Age Guess-timation

Okay this is bugging the Hades out of me. How old is Nico? He's born in the early 1900's but how old would he be now? I hope 15. Why? I don't know. Also, what's Annabeth's step-mom's name? I was thinking of writing something about her. Okay thanks. Oh, by the by, I've posted a new chapter in my story on the FanFic site! Chex it out!
