Chapter 3: Returning to Hogwarts

Before anyone knew it the time to return to Hogwarts came upon them. They stopped by to pick Severus up but found that he had already left with his mum. Mentally grinning Petunia felt the car turn around and head for Kings Cross. They arrived with ten minutes to go. Petunia loaded the trunks onto trollies and they hurried into the station.

Petunia showed Lily how to get onto the platform and said goodbye to their parents. The man said, "I'll make sure that they get back to the other side."

"Thanks," Petunia said and then they went looking for a compartment.

The only one had Severus in it. He was reading a book, already changing into his Hogwarts robes. True they were as second hand as possible but they were clean. He went white when Petunia entered, with Lily.

"Sev," she cried out.

"Hi, um, Lily," he said.

"Don't worry, I won't hurt you," Petunia told him and they both sat down.

"That's…nice," he said.

"I can't believe we're finally going," Lily said. "Petunia told me that I'll do fine."

"And you will."

"See, I told you so," Petunia said and she pulled out another book that Lily had gotten her for Christmas.

"So what house are you hoping to get into?"

"I don't know," Lily said. "I mean Petunia said that the other houses are just as good."

"My mum freaked out when I told her that Petunia is a Slytherin," Severus said. "She says that she doesn't think that Slytherin is the right house for me."

"Oh great," Petunia muttered.

"But I want to be in Slytherin," Severus told them.

"Then just do it," Petunia said. "Don't listen to your mum."

The compartment door opened and in walked three boys. Remus was among them and she wondered what caused him to fall into company with them. They were also talking about houses too but stopped when they saw them.

"Well look what we have here, an angel, a bookworm, and a butt ugly pooch," he said.

"Hello, Remus, how are you feeling?"

"Oh you know this butt ugly pooch," he said.

"Don't call her that," Remus said.

"What house are you in?"

"Slytherin," Petunia answered.

"Well looks like we know what she's like," the boy said. "I'm James Potter, the heir to the noble house of Potter and I know that I'll be in Gryffindor."

"Must be nice to know where you're going in life," Petunia said.

"Why don't you shove off," Lily said. "And don't call my sister that."

"The little girl is talking."

"Shut up, Sirius, that's my future wife that you're talking to."

"Wife, wife, I don't think so," Lily snarled and Petunia stood up.

"I would advise that you leave," she said, "Don't talk to my sister like that and don't insult me. I have to put up with a whole house of them and I'm not putting up with you."

"Let's get out of here," Sirius said. "Come along, Remus."

"No, you insulting Petunia," he said and he came over and sat down.

"Hay, James, want to see something?" Petunia asked and she changed into a panther.

The boys bolted and left.

"Oh that's just so cool," Lily said when she changed back.

"Thanks," Petunia said, setting down, "Glad that you defended me."

"Your helping me, I can't allow you to be bullied."

Petunia smiled at him.

When the train finally came to a stop the students got off. Petunia told Lily, Remus, and Severus that they were going to be taking the boats across the lake. She turned and headed for the carriages that would take the older students to the school. The carriages were drawn by creatures that her mother had told her could only be seen by those that had seen death.

Watching your demigod friends die fulfilled that requirement.

She got in and found that it was occupied by several people in Hufflepuff. She closed the door and the carriage set off. It took ten minutes for the carriage to pull up in-front of the school and everyone to get out. She hurried up the steps and found Professor McGonagall watching the students.

"Welcome back, Miss Evans," she said.

"Thank you, Professor," she said and she hurried into the Great Hall.

Twenty minutes later Professor McGonagall appeared with the line of new students. She saw Lily, at once and smiled. The students stopped and the hat and stool were placed in-front of them. The hat sang a worst song then last year but she clapped with everyone when it was over. And then the sorting started.

Every time that a student was sorted into their house that house cheered. When she heard "Black, Sirius" she decided to pull a prank on him. Since he was friends with Potter then he would want to be in Gryffindor. She muttered a spell under her breath and then, "HUFFLEPUFF!"

"WHAT!"

He yanked it off and looked at it, horrified.

"Head for your house," Professor McGonagall ordered and he was force to go there.

"Evans, Lily" she waited as the hat was placed on her head.

"SLYTHERIN!" the hat shouted and she took the hat off and hurried over to the Slytherin table.

"Great, we've got another Mudblood in our house."

"Want me to cut off your balls, Crabbe?" Petunia asked him and he yelped.

To Petunia's surprise Remus ended up in Slytherin as well and Petunia personally shook his hand.

"I told the hat that I wanted to be in with my friends," he said.

"I'll have your back, won't I?" Petunia said and everyone looked down at their plates. "Watch this."

She muttered the same spell as James put the hat on his head.

"HUFFLEPUFF!"

"WHAT!" James said and everyone laughed.

"Just go to your house," she said.

"I'm going to talk to my father."

"To bad that won't work," Petunia said, grinning.

Severus didn't get his wish and ended up in Slytherin as well. Lily grinned at him and he returned with a small smile. Once the sorting ended Professor Dumbledore stood up and she turned her attention to her brother.

"Welcome back, to another year at Hogwarts. I have a few announcements that must be handed out. First: Mr. Filch has added twenty-two new items to his growing list of items not allowed in the school. If anyone wants to see the list it's tacked on Mr. Filch's front door. Quidditch try out will take place during the second week of term. Those in their second year, and above, that wishes to try out for their house team please contact Madam Hooch! Also those interested in study time, and help with homework, can join Petunia Evan's study group which is open to all students from any house. Last year's effort was a success.

"The Forbidden forest is forbidden to all students and Professor Sprout has also asked me to remind you that the new tree, the Whomping Willow, is not to be approached by any student. Thank you."

And he sat down.

The feast started and everyone was so busy with their food that they didn't notice that Petunia gave Hecate an offering. She made sure the mist was up so that if anyone did look her way they wouldn't notice. Everyone was talking about their summer and the moment someone asked about the Dark Lord Petunia turned her attention to that person. When that person turned they at once returned to their meal.

When the feast ended the older students headed to their dorms, leaving the new students with the Prefects. Narcissa asked about what she thought about that insane tree that had been planted.

"It wasn't here last year," Petunia said.

"True," she answered.

Narcissa said the password and they all entered, heading for their dorms. As she was changing Petunia got a feeling that the Prefects would bully Lily for being a Muggleborn. She left the dorm and headed down to the common room. Sure enough Severus was comforting a sobbing Lily.

"I guess that my talk last term wasn't headed," Petunia said and her flaming whip appeared.

The Prefect screamed as Petunia launched it at the Prefect. She screamed as she burned, the first years backing away.

"Insult, attack, or make Lily feel unwelcome and this will be your punishment," Petunia said. "I'm not a witch you mess with! Got that!"

They all nodded.

"What in the-."

"It seems that Miss Prefect needs the wing," Petunia told her.

"I'll fire call Madam Pomfrey," she said and then she left.

"She's scary," someone said.

"I'm a defender of all Muggleborns and half-bloods. Don't miss with me or you will…burn. Remus Lupin, Severus Snape, and my sister, along with any muggleborn or half-blood, are under my protection. Come along, Lily, I have something for nerves."

"Thanks," Lily said and she was led away just as Madam Pomfrey arrived.
