Hogwarts
December 27th, 1973.
"How is she?"
"Are they going to be alright?"
"Who are they?" Dahlia could hear hushed voices from across the room. She slowly opened her eyes and saw she was placed in a bed in the hospital wing. She looked around in the room and to her relief she saw Lily on her left and Violet on her right. She searched for the reason of her waking up and spotted three boys talking to Professor Dumbledore and what looked like Madame Pomfrit's daughter. One of the boys looked up and saw her. He had black hair and brown eyes. Pretty tall. "She's awake!" Dumbledore hurried over to her while the young lady held the three boys back.
"How are you doing Miss Evans?"
"I'm fine. I have to talk to Headmaster Dippet..."
"Headmaster Dippet died in 1960, and then I became Headmaster."
"What do you mean 'died in 1960'? The year is 1957!"
"No. The Christmas 1957 you and your two sisters disappeared in the Forbidden Forest..."
"No! This can't be!"
"I am sorry to tell that it is the truth. I have called for your parents, they will be arriving tomorrow."
"But they can't see the castle, they are muggles!"
"They don't know that. If they are told before they arrive that they will see a castle I hope they will be able to see it."
"But... How long have we been gone?"
"You disappeared in 1957 and it's the year 1973 now. You have been gone for 16 years."
"16 years! But... then I must be over 30!"
"No. A preserving spell was put upon you it seems. You are still 15."
"Thank god."
"Your parents will bring a sister of yours. Your birth mother had another child the year you disappeared, but could not keep her. She searched up your adoptive parents and asked if they would take care of her. They accepted because she was your sister. She's now a 16 year old muggle."
"A muggle?"
"Yes. Even though she is your half sister she does not keep enough magic in herself to be trained as a witch."
"Oh." Dahlia leaned back on her bed.
"Maybe you want to met your saviour?" Profess... No… Headmaster Dumbledore, she reminded herself, asked. She smiled and nodded.
"Remus, the young lady wishes to meet you." One of the boys nodded and walked over to her. He was tall, as the two others, but his hair was of a brown shade, the others were black.
"Hi." He seated himself in the chair placed next to her bed.
"Hi... How did you find me really?" Dahlia asked and Remus told the whole story as far as he knew from beginning to end.
