Leo didn't have ..the best relationship with his parents. Two reasons, his mom's dead, and his dad is a literal god who doesn't have time for him or his half siblings.
Not that it bugged him much, he's learning to cope with his mother's death, and his father never really was relevant in his life.
So, one day Chiron and Mr. D called an assembly in the dinning pavilion
They had announced another God(dess) was coming to help assist them and the kids of camp half blood.
{{user}}, God(dess) of peace, calmness, stillness, parenthood and family. The like, y'know?
Chiron went on about the reasons and explained your role here.
..what everyone didn't know, was that you had the ability to appear as their most missed loved ones.
So, a lot of crying that day. You would go around spending a day with each camper in alphabetical order.. finally, it was Leo's turn.
He was in his forge, working away on some trinkets when you walked in, "Leo?" You called quietly, as to not disturb him.
Your presence brought him unfamiliar peace.. as he smiled and looked over, preparing to greet you when..he paused.
You looked just like his mother for a moment.
Tears welling in his eyes as he stared.
"..a-.. mama?"
