Chapter 2: Petunia Gives Mrs. Snape a Lesson

The dark was where Petunia's power was more than a match for any Pureblood witch or wizard. She shadow traveled to the Snape's house and sensed no wards. Meaning that no magic was done in this house! She pounded on the door and waited. The door opened to reveal a drunken Mr. Snape.

"Who the bloody hell are-?"

She side kicked him, knocking him out cold. Filthy drunk! She walked in and saw Mrs. Snape holding a knife.

"What did you do to my husband?" she snarled.

"Some husband, blessed child," Petunia hissed and shadows flooded the house. She whimpered. "I think that we need to have a very long talk."

She extended her hand and one of the shadows knocked the knife out of her hand.

"Where's your wand, witch?" Petunia asked.

"I don't need to answer to some filthy Mudblood," she snarled.

"Once again, with the names," Petunia said. "Living among muggles has taught you nothing about them. And if you think that this drunken moron represents all muggles then you're mistaken. And trust me, Snape; I'm not a muggleborn witch."

She laughed and then the shadows lifted her off her feet.

"What the hell are you?" she asked.

"Why, I'm a child of Hecate," Petunia said to her, "And you teaching your son to hate those that are different from him will cause him to become one of Tom's supporters. Your little boy will be bathing in the blood of babies, pregnant women, and men."

She whimpered and Petunia could feel the fear flooding through this woman.

"Oh by the way," Petunia said, "If you think that the Dark Lord is pure, you are your own worst fool. He's a mass murdering half-blood who hates other half-bloods and muggleborns. He's another Hitler!"

She let her go and Mrs. Snape went for the knife, however the shadows knocked it out of the window. She then let out a scream as Petunia made huge raven's wings appear out of her back.

"MUM!" Severus screamed and then screamed when he saw her.

"Word of warning, Severus, you will go to Tartarus if you join Tom Riddle," Petunia advised. "He will take Lily and make her burn because she's not pure."

And then Petunia vanished in a cloud of purple smoke.

"There's no hope for Mrs. Snape," Petunia told Lily the next morning.

"I figured that much," she said. "Do you think that Severus will act like her at Hogwarts?"

"Gods, I hope not," Petunia said.

Though she had a feeling that it was going to take a lot to keep that from happening!

Petunia read all her books that she had gotten, determined to continue to prove that her first year wasn't a fluke. Lily was all excited about her new books and learning magic with her wand.

"So why aren't you casting?" Lily asked her.

"Because it's against the rules to do magic outside of school," Petunia answered.

"Well that sucks," she said.

Petunia snickered and said, "Yes, but the rules must be followed."

"But you'll be able to use it when you get there?" she asked.

"Of course," Petunia said. "How else am I supposed to put my fellow Slytherin's in their place."

Lily grinned.

A/N: If anyone wants to know why Petunia didn't get into trouble for using her abilities it's because Hecate's magic is unknown to the Wizarding world and thus the Trace doesn't recognize it. Oh this story has the blood and gore. At some point I'll make it mature.
