Fostering Foster

Say what?

"Percy come here." My mom called out. Reluctantly, I pulled myself out of bed and trudged into the kitchen.
"What?" I groaned sleepily.
"I, um, have made a decision," She bit her lip,"I...I'm going to adopt someone."
I was fully awake now. "You're gonna do WHAT?!"
"Adopt someone, a girl. You're always so busy with, um, saving the world," she winked, "that I sometimes get lonely. You understand, right?"
I smiled, "Of course I do."
Honestly, it was a lot to take in, but if it made my mom happy, I'd accept it instantly. I left for my room to tell Annabeth.
When I got there I Iris Messaged her. As I waited for her face to appear, I thought about who we were going to adopt.
Who was she? How old is she? What's her name?
"Hey Seawead Brain, are you going to greet me, or just stand there?" A familiar voice sighed.
"Oh, um, hi..." I rushed, feeling heat spread across my face, "Guess what? My mom is going to adopt someone!"
"Okay, now tell me the real reason you called me."
I was confused. "I just did."
Now she looked confused. "Wait, really?!"
I nodded.
"When?" Annabeth asked.
"Tomorrow," my mom answered, coming through the door. I looked at her quizzically.
She sighed, "So start cleaning. Oh and be nice. She's been to many foster homes and, um, doesn't exactly fit in."
"Um, okay...what's her name?" Annabeth asked from behind me. I jumped. I forgot I Messaged her.
My mom smiled,"Sophie Foster."
