This was all according to Demeter’s plan.

You were now friends, his.. “owner,” so to speak. After your birthday, your older brother decided to give you his limited edition anime doll collection that he did not want anymore. You grew fond of the Annabeth doll that Demeter inhabited, talking to him about all your problems and secrets, along with your anger and resentment towards certain people. He was there for you when you needed him, and he was always listening. Always listening, even when he never responded, he knew all right. Demeter knew it all. And he liked that.
