Chapter 1:Going Back to Diagon Alley

Petunia Evans was having a great summer. She spent about three days back at Hogwarts brewing Wolfbane and spending time with Lily. She was nervous about her first year at Hogwarts and Petunia told her that there was nothing to worry about.

"What if no one likes me," she asked.

"People will like you," Petunia assured her.

She had gotten several letters from Narcissa, all surrounding the dumb people that she called family and the continuing problems with the Dark Lord. He called himself Voldemort but Petunia knew that he was Tom Riddle. Why people change their names, she would never understand. She also heard that Narcissa's cousin, Sirius, was starting Hogwarts and was already causing problems at home. Petunia had a funny feeling that he was going to cause problems at school.

In July Petunia was charged with taking Lily to Diagon Alley to get her things since she was the big sister and knew where it was. So they took two buses to get there. While they were on theirs she noticed that so was Severus and a woman that had to be his mum.

"Sev," Lily cried out.

"Again, with the nickname," Petunia muttered as Severus went pink.

Mrs. Snape didn't look impressed but neither was Petunia.

"I thought that you were going to-."

"My son is too young to experience it," Mrs. Snape said, "Well I've been hearing a lot about you, Miss Evans."

"And I thought that you didn't get news," Petunia said.

"I manage," she said, "Helping werewolves out."

"I'm going to expand," Petunia told her.

"Filthy beasts," she muttered.

Petunia at once didn't like her but Severus looked a bit impressed.

"My sister is a genius," Lily said.

"My son is better!" she said.

"Mum," Severus begged.

"Don't talk to us, Mudblood," she snarled and she pushed Severus away.

"What is her problem?" Lily asked her.

"I don't think that you want to know," Petunia answered.

She was used to being called a Mudblood that the word didn't bother her.

When they arrived in Diagon Alley Petunia allowed Lily to take in the whole of the place. They then went to Gringotts where Lily changed some muggle bills into coins and Petunia took her down to her vault. Lily was shocked at how much money that she had made from her invention.

"Don't worry, I'll buy you something amazing," Petunia told her as she made her withdrawal.

Once they were out Petunia took Lily to Madam Malkin at the same time that the Snape's were entering as well. Mrs. Snape looked furious but the look that Severus gave was that he wanted to get fitted.

"We don't have the money," she said, "We'll get your wand, and potions supplies, new, but the rest is second hand."

And they walked off.

"Come on, let's get your robes," Petunia said and they waited their turn.

Petunia and Lily didn't see the Snape's anymore that day. Petunia figured that Mrs. Snape was ensuring that they didn't meet until the Hogwarts Express where she would have no control over it. When they entered the animal shop they were surrounded by all sorts of animals. Petunia used the school owls, so she didn't need to buy one, but Lily at once went for the most impressive animal in the whole place: a phoenix!

"Oh I want it," she said.

"It has to bound to you," the owner told her, "Which I doubt that-."

Before she could finish there was a stream of scarlet light and the owner muttered, "Fifty galleons."

Petunia shoved them into her hand and they left with Lily's pet. She would have to use the mist to cover this thing. Petunia and Lily didn't see the Snape's on their way back from Diagon Alley. Petunia figured that Mrs. Snape was making sure that they weren't having any contact. Petunia also saw that this was hurting Lily and she made a vow that she would personally address this. She knew where the Snape's lived and she was going to face the whole lot of them.

A/N: Petunia has gotten this fed up with this nonsense.
