It was the day the students were going home and Rosa had just found an empty compartment to sit in. She put her stuff up in the rack and sat down staring out the window, thinking about why she didn't agree to go stay with Lily for Christmas.

Flashback-

Rosa walked into Camp Half-Blood and went straight to the blue farm house to find, the centaur, Chiron, trainer of heroes. She took a deep breath and sighed. "Chiron, I'm going to a private school in England…"

Chiron looked down at Rosa with his deep brown eyes. "I understand, Rosa, and I will support you. But may I ask you some questions?"

Rosa smiles up at Chiron, glad he would support her. "Sure."

"What is this boarding school's name?" Chiron he folds his arms.

"Hogwarts."

"Where is Hogwarts?"

"Scotland, Great Britain. Usually the students of Hogwarts are from the United Kingdom and Ireland, but since my mother was and Aunt Sally is originally from London, England and both of their entire families have gone there...Aunt Sally wrote to the Deputy Headmistress and explained this and that my mother had wished for me to attend, so she made sure I'd be able to attend."

"I see. Well, you should go say goodbye to Annabeth, she's come to be very attached to you."

Rosa smiles a true smile at that. "I know and I've become attached to her, she's like a little sister to me." She hugs Chiron, he was the only adult man she could hug without panicking, and whispers. "Promise that you'll keep an eye on her while I'm gone…"

Chiron hugs Rosa back and kisses her head. "I promise."

Rosa pulls away from Chiron and goes to the Athena cabin and pokes her head in. "Annabeth?"

A seven year old girl with wavy golden blonde hair looks up at Rosa and smiles, her usually intense gray eyes sparkling. "Rosa!" She runs to Rosa and hugs the older girl.

Rosa hugs the younger girl and ruffles her hair. "Annabeth, can you walk with me, I need to talk to you?"

The younger girl nods and leads the older girl out of the cabin.

Rosa walks with Annabeth to the stables. "Annabeth, I'm going to be leaving for London, England tomorrow…"

Annabeth tilts her head and looks up at Rosa. "Why?"

"I've been accepted to a really good boarding school, the same one my mother went to... " Rosa states, looking down at the shorter girl.

Annabeth's eyes lit up at the mention of the school. "Wow, I wish I could go… You'll do great right and write to me?"

Rosa smiles and looks at the sky. "Of course I will. I will write to you once a week and tell you how school's going. And I promise you that I will come home for Christmas break and spend half of it with you and half of it with my brother."

End Flashback-

Rosa snaps out of her thoughts when she hears her name being called. She looks towards the voices and notices it belonged to a very concerned looking Severus Snape. "What?"

Severus sits down beside Rosa, him and Rosa's other close friends had entered the compartment while Rosa was staring out the window. "I've been trying to gain your attention for three minutes now... Are you ok?"

Lily and the others were watching Rosa, wondering the same thing Severus had just asked.

Rosa smiles weakly and nods. "I'm fine. I was just thinking about a girl at the camp I go to every summer and my brother…"

Remus looks at Rosa curiously. "Who's the little girl you were thinking about?"

Rosa looks at Remus. "Her name's Annabeth Chase. She's a demigod like Mari and me… She's the daughter of Athena, Greek Goddess of Wisdom and Strategy. And she gets her brains from her mother."

Lily smiles and tilts her head. "You seem fond of her."

Marissa nods and glances at Rosa. "I'd love to meet her someday, Ro."

Rosa then looks at Peter, Remus, James, and Sirius. "You four would love Connor and Travis Stoll, they're the twin sons of Hermes, Greek God of roads, speed, messengers, commerce, travel, thieves, merchants, athletes, and mail deliverers. They are pranksters just like you."

James smirks. "Wow! We'd love to meet them!"

At the same time, Sally was sitting in the her apartment, Percy asleep in his bed, having a really horrid fever, and Gabe was out drinking with his buddies. She walked to the kitchen table with parchment and a quill. She sat down and began to write:

Eileen,

I know that I haven't really spoken in a few years, not since I wrote to you about Isabella's death, but I must ask something of you as my friend… You see, I'm raising Isabella's daughter, Rosalina Isabella Smith, and she started Hogwarts this year… I'd like to ask you to bring her home to my apartment, I'd come to pick her up for the holiday myself, but my son has been sick for the last two days and I don't feel safe leaving him home with his step-father. I await your answer, so that if need be I can write to someone else to bring her home.

Sally Jackson

She then went to a room she had charmed to be hidden from Gabe and walked in, letting out her Spectacled Owl and tied the letter to its foot and took it to the window. "Go, Merlin."

The owl took off into the air and flew away.

Sally sighs and walks to the room Percy and Rosa share and sits on the edge of Percy's bed, brushing hair out of Percy's sweaty face.

Two hours later, Eileen Snape was sitting on the porch of her house, when she saw a Spectacled Owl fly to her. She held her arm out and the owl landed on her arm.

The owl hoots and holds its leg out to her.

Eileen unties the letter and opens it reading it quickly. She then gets up and walks into the house, going straight to the study. She grabs a quill and parchment and quickly writes a reply:

Sally,

Of course I'll pick Rosalina up and bring her home. You just worry about your son. Oh and I'll also be bringing my son with me when I come to bring Rosalina home. Always good to hear from you, write more often.

Eileen Snape

She then ties the letter to the owl's leg and sends it on its way, after giving it a treat, before going to the kitchen.

Another two hours later, Sally looks up from getting a bowl of ice water and a rag, to see her owl flying in through the window. She walks to her son, sets the bowl on the table, and dips the rag into the water, before wringing it out. She then lays it on her son's head, before going to the living room and taking the letter off the owl and reading it. She sighed and smiled, whispering. "Thanks, Eileen…"
