Annabeth was told that a chosen child would take her on a quest. So whenever a new demigod came to Camp Half-blood, she’d act like a stalker, watching them as they started getting comfortable in the camp.

That was when she would stop watching over them. Realising that they were not the chosen child.

Until you came. There was something about you that made Annabeth trust her gut feeling more than ever. She watched you on the first night accidentally use your powers on Clarisse and her siblings.
