A.N I don't own Harry Potter

Sara was shocked when she received a letter from Remus and Sirius about her mother's birth family. Sirius suspected along with Remus and her father that her mother wasn't a muggle born.

Prongslet,

The mystery of your mother's birth family has been solved. She was born Cassandra Aurora Flint on January 1, 1960. Your biological grandparents have long since passed. Do not fear your mother's birth relatives being death eaters. They were not. Your uncle Justinian is a hit wizard who helped to catch many of the death eaters. You have an older cousin too, Marcus who graduated this past spring.

When you see your oncologist in January, I will need to mention your maternal grandmother and her side of the family. Thyroid cancer has killed them. That charm that has benefitted you only has come out recently. Petunia and Vernon were horrified to learn your mother had been kidnapped as a baby. They will be following your parents' plan to have them listed as co-magical guardian with me.

Love,

Sirius

P.S. It will get out that your mother is the Flint's missing daughter. The announcement will be kept strictly controlled. I recommend telling Cassius."

Cassius was with his witch and saw the letter. "Explain…"

"It's going to get out so I will start with my mother first. The Evans', my adoptive grandparents adopted my mother in London. She was found in a local hospital and when no one claimed her, she was adopted. My father, Remus, and Sirius agreed that my mother couldn't be a muggleborn. They never found out who kidnapped her to begin with."

Cassius knew whoever kidnapped the Flint heiress ignited a blood feud. To take a pureblood child and place them with muggles is a mandatory dementors kiss.

"Now explain the thyroid cancer…"

"I would have told you. In September, I started having problems swallowing and losing my voice randomly. Madam Pomfrey diagnosed me with stage one thyroid cancer. It was why I was spending nights and weekends in the hospital wing. I was spending two hours a day getting tumor shrinking charms applied. I'm in remission."

Cassius looked at Sara in shock. He understood why the thyroid cancer is need-to-know and the Gryffs didn't deserve to know. They have been right bastards with their need to control her and their wild accusations of cheating. Anyone with half of a brain would know Sara is innocent.

It was three days later when hell broke loose when Cassandra Flint was exposed as being the late Lady Lily Potter.

"Case Closed, Heiress Cassandra Flint Dead At Twenty One January 1 1960 - October 31, 1981"

"Cassandra Flint, Mother Of The-Girl-Who-Lived"

Sara was feeling uneasy. That's when Lucifer, Sirius' owl dropped off a letter. Cassius went over to the Gryffindor table to comfort his witch.

"Pup,

The media has been blocked from going to Hogwarts. Justinian has filed the paperwork for magical guardianship over you. The ministry has accepted and will acknowledge your parents' final wishes. Now, Justinian, Cassopeia, Pollux, Remus, and myself are going to formally challenge your sorting into Gryffindor. Dumbles had far too much to gain by rigging the Hat.

Love,

Sirius"

Cassius smirked because it could be proven that Sara's sorting was rigged for Dumbledore's gain.

"Are you okay?"

"I am, thank you."

Severus knew Potter would be resorted to his house. Dumbledore tried to pass Sara off as a clone of her parents. She looked more like the Black side of the family and she wasn't brash or reckless like a Gryffindor. As far as the thyroid cancer is concerned, Potter has been quiet about the whole ordeal. Warrington knows but he wouldn't advertise it.

Severus, Pomona, and Filius were there when Noble and Ancient Families of Black and Flint formally contested Sara Potter's placement in Gryffindor.

"Board of Governors, Albus has felt a psychotic need to control Heiress Sara Rose Potter by placing her in Gryffindor. Here is exhibit one, the sorting hat was jinxed."

The Governors gasped in horror. "What of Heiress Potter's behavior makes her clash from the typical Gryffindor?"

Filius went first. "Heiress Potter values her studies. She is tied for first in her year. Sara prefers to get all of the facts before deciding."

Pomona knew Sara wasn't quite Hufflepuff material but Helga would have loved to have her in Hufflepuff. "Heiress Potter has never judged the children of death eaters, blaming them for the sins of their parents and grandparents. She also works harder than her housemates which is reflected in her school work."

Severus went last. "Heiress Potter has had to use tactics to out-maneuver her housemates with their sick and psychotic need of control over her. Her housemates have been at least five steps behind her. She knows that if she is kept in Gryffindor, she will have to eliminate her competition for prefect because muggleborns and half bloods are shown preference for that honor."

The evidence piled up that Heiress Sara Rose Potter is not Gryffindor material. The Hat spoke.

"Albus compelled me into placing Sara Potter in Gryffindor. I felt she was best for Slytherin."

The Governors examined the evidence. "Heiress Potter will be restored."

An elf was sent to bring Sara to the empty classroom. Minerva and Albus were gagged from speaking. Lupin was waiting for his "niece".

"Remus, what is going on?"

"Tonight the board of governors heard the case to resort you. It's been approved."

Sara was brought in and when the Hat was placed on her head. The decision was instant. "Slytherin, where you should have been from the beginning."

Severus,Remus, Sirius, Electra, and Justinian breathed a sigh of relief. Severus did need to know about her medication status for the night."Miss Potter, we need to get you cleared out of Gryffindor tower. What about your medications for tonight?"

"All of them are being stored with Madame Pomfrey, Professor Snape. I usually take the vitamin d and calcium pills before curfew."

Justinian could see Sara breathe a sigh of relief. He pulled his niece into a tight hug. This wasn't the reunion he had been hoping for with his sister alive. "The Gryffs won't try anything with all of us in the tower."

"Uncle Justinian, that would be the ultimate dare for my former housemates."

Remus and Sirius agreed with Sara. "Unfortunately, Sara is right. Electra, you may be the one needed to see go into the girls' dorms. The wards can only be dropped if a student is in grave danger in Gryffindor."

"That's not a problem."

On the way to Gryffindor tower, Severus stopped at the hospital wing to get Sara's medication. Sara gave the password to the Fat Lady. "Gold And Crimson Lions Den". The door opened to shocked lions. Minerva and Albus were whiter than sheets in the Governors meeting because this could mean the end of their careers.

Sprout and Flitwick were there too. They didn't trust the Gryffindors. In the 4th year's girls' dorm in Slytherins, the girls knew what it meant. Potter was resorted. Marcus had sent letters to the Flint and Selwyn cousins in Slytherin. They all agreed with Marc that their missing cousin would be in Slytherin and the retaliation would be severe from the lions.
