"You wouldn't believe me even if I told you, Black," Severus replied, his gaze fixed on the water beyond the window of his cell.

Sirius smirked. "Try me."

Snape scoffed. "Alright, then. When I learned Lily's son had been sent to live with Petunia, I Obliviated that wretched woman, erasing every memory she had of her sister. I did the same to her husband before using a False Memory Charm to convince them that they were taking a one-way trip to Antarctica, along with that pet pig they call their son. Then I burned their house to the ground."

Sirius stared at him for a moment. "And what about Harry? What did you do with him?"

"I dropped him off at my house before I dealt with the Dursleys," Severus said dismissively, waving a hand. "Shortly afterwards, I did some digging and discovered that Mrs Evans had a cousin who lives alone in a mansion in the countryside outside London. All I know is that the house was once owned by an old professor who died in a train crash many years ago. I don't think even Dumbledore knew the woman existed."

"This cousin of hers... what's she like?" Sirius asked curiously. "She isn't anything like Petunia, is she?"

"I didn't have much opportunity to get to know her, but she came across as rather jaded. She didn't exactly believe me when I told her I was a wizard, either, until I demonstrated the Patronus Charm."

"Must've been one hell of a shock."

"Indeed. Most Muggles would've fainted at such a display. She, however, took it rather well and simply asked why I'd come to see her. I told her everything about the circumstances surrounding Potter's situation, and she ultimately agreed to take him in."

"I suppose the Ministry didn't take kindly to you kidnapping their precious hero, did they?" Sirius asked.

"I explained everything to Dumbledore who tried vouching for me, but Crouch wasn't having any of it." Severus sighed. "So here I am."

Ron & Percy: Those two had a Death Eater who was disguised as a rat living with them and sleeping in their rooms until the events of POA. Pettigrew could easily have killed them or blown up the entire burrow if he had wanted to.

Neville: Considering he was being taught by one of the Death Eaters who tortured his parents into insanity and invited him for tea at one point in his fourth year, it's only logical something like that would mess him up.

Aside from him setting up security cameras where the Goblet of Fire is, which leads to Barty's capture much sooner, I've got nothing else.

I only found one but the author quit after chapter 2.

“Y-Y-You’re going out with Tracey Davis?” Harry asked, as though he needed to hear it again to make sure he hadn’t imagined it. He had even glanced out the window, half-expecting to see pigs flying or the sky falling.

“Yep,” Ron confirmed casually for the third time. He stood in front of the mirror, adjusting the tie on his dress robes, which he had transfigured to look newer and more modern. “It’s not a big deal, mate. I’ve worked with her during Potions and Herbology. We’re on good terms.”

“B-B-But she’s a Slytherin!” Harry was now pacing back and forth as though he were completely off his rocker. “You hate Slytherins!”

“No, I hate Snape, Malfoy, and his cronies,” Ron clarified. “Most of the others are decent blokes.”

“Still, I bet Tracey’s family were among the many Purebloods who supported Voldemort. They might’ve even had family members among his followers.”

“On the contrary. They were one of the Pureblood families that actively opposed him.”

“And how do you know that? Did she tell you? She could be lying, you know.”

Ron smirked before dropping the bombshell.

“Because her dad and mine are good friends. They’ve known each other since their first year at Hogwarts. Also, some of her uncles and aunts are Aurors.”

“But they’re still Slytherins. Let me ask you something: did they have any friends who joined the Death Eaters?”

“Well, there was one—”

“I knew it!”

“He might’ve been the only one who was actually put under the Imperius Curse. Too bad they got ’im.”

“Dang it—wait, what do you mean, they got him?”

“Bill and Charlie liked him, too. He was the one who gifted them their toy broomsticks for their first birthdays.”

“What do you mean, they got him?!” Harry asked again.

By then, Ron had finished adjusting his tie. He turned to face his friend, seemingly ignoring the question.

“Look, you’ve had a lot of bad experiences with Slytherins,” he acknowledged. “And I’ve had my fair share, too. But Snape and Malfoy are some of the exceptions, not the rule—”

“But Slytherin is known for producing more dark wizards and witches, for crying out loud!”

Ron narrowed his eyes and thoughtfully placed a hand against his chin.

“Hmmmm. Well, when you put it like that, you have a point.”

Harry sighed in relief.

Finally. Took you long enough.

Unfortunately, Ron’s next words immediately sent them back to square one.

“But Gellert Grindelwald wasn’t a Slytherin, nor was he even a Hogwarts student. In fact, he made all those dark wizards and witches look like model citizens.”

“B-But—”

“Harry, how many Slytherins do you think joined You-Know-Who’s cause?”

“I don’t know. Maybe ninety-nine percent?”

“Forty-two percent, actually.”

Harry stared at him.

“...What?”

“After the whole incident at the Shrieking Shack and the truth about Sirius’s innocence, I sat down with Dad and asked him to tell me everything he knew about the war. Everything. From what I learned that day, thirty-eight percent of You-Know-Who’s followers were Ravenclaws, four percent were Hufflepuffs, and the rest were Gryffindors.”

Harry's jaw dropped, “Wait... what?”

Ron shrugged, "Yeah, I was shocked too. I forgot mention this as well: My grandma was a Slytherin."

Although massively disappointed that he won't be going to Hogwarts with Lily, he has an absolute field day during his first week when learning that the Dark Arts is part of the school curriculum.

Please?
