Back at Hogwarts, while everyone was in class or doing homework in the library, there was one student who was doing neither. Actually she had just made her appearance by landing in Dumbledore's office using Floo Powder, her name is Sydney. The fifteen year old, beat up girl limped over to the nearest chair before plopping down, waiting for someone to arrive.
"Hello Miss Potter. I have been expecting your arrival," a tall, old man with a silver beard and moon crescent glasses speaks as he walks into the office. "I would ask for your experience's, but at the moment you need to see Madam Pomfrey".
"I'd rather not speak of the events, Professor Dumbledore" Sydney looks over at her professor. "Can I just go get some sleep?" she yawns, proving her point. "I've honestly gotten practically no sleep in six months or more".
As Dumbledore looks into the weary teenager, he can see in her eyes that she has seen and done things that no fifteen year old should endure. "I won't pester you for the information right now, but you do know we may need everyone to help us defeat Voldemort". Dumbledore reached out to help Sydney up. As soon as she is up, they both make their way out of the office and down the steps.
As they walked through the corridors of the castle, they rarely saw anyone, and if they did Dumbledore made sure that they left them alone on the journey to the infirmary. As soon as they reached the infirmary, Dumbledore helped the weary fifteen year old onto a bed as another lady busts out of her office towards them, "Oh my, what happened to her Albus?" the scrawny nurse asks as she starts to tend to the fifteen year old.
"That Poppy is not my story to tell," the ancient wizard responds as the infirmary doors burst open with a stout, frog looking lady strides in.
"What is the meaning of this? Is this your way to try and tell us He-Who-Must-Not-Be-Named is back, by having Potter disappear since last school year and magically showing up in injuries?" the pink frog like lady screeches.
"No, Dolores. Sydney being gone had nothing to do with Voldemort, as she was dealing with family problems the whole time" Dumbledore sternly responded.
"Doubt that, her mother is dead. She is an orphan just like her lying cousin. No one else was named for her family besides everyone who is dead" Dolores shoots back.
"On the contrary, she does have a family, but they would like to be kept a secret. If you want we can go continue this conversation in my office so Poppy can tend to her patient," Dumbledore states as he walks out of the infirmary, leaving Dolores no way to deny his offer.
Sydney soon fell asleep after taking a sleeping potion, while she was sleeping Madam Pomfrey was tending to her wounds and trying to keep any student out of the infirmary, especially Sydney's cousin.
