Upon finding that Annabeth was a demigod, Luke and Thalia agreed that she could run away with them and Luke promised that he wouldn't let anything hurt her and they would become a better family than her old family.
Luke gave Annabeth a bronze knife, which he got from Halcyon Green, so she would be able to protect herself with something better than a hammer for monster slaying.
He would occasionally ask her to return home, but Annabeth always refused.
Her father then sent her his Harvard college ring, in hopes that she would remember him by it, and be convinced to come home.
Every time a new camper came to Camp Half-Blood, Annabeth wondered if they were "the one," because Chiron told her that she would have a part to play in the Great Prophecy.Strangely, three years later, Annabeth said that she did not know the whole prophecy, but she may have lied to Percy to protect him after being told to do so by Chiron.During these three years, Annabeth would talk to her father via letters, as phones were too dangerous for a demigod.
