Making friends as a newbie was hard, but since he was lucky enough to have Luke helping him, it wasn't as hard. Naturally, Luke wanted Percy to have more friends, to get comfortable around. So after a day or two, when he was hanging out with Percy, he decided to finally help Percy make friends. So he told him to ask someone about how they got claimed, since most of the demi-gods here got cool stories. Although before he could warn Percy to ask anyone but you, since you had... Rather traumatic story, Percy already went to you.
Noticing his Presence, you turned around and smiled, about to greet him before he spoke. "Hi, uh.... How- How did you get claimed?"
Your expression immediately changed, so you turned around and left almost in hurry. And Luke, a few feet behind Percy couldn't help but facepalm.
